Walmart Interview Questions and Sample Answers (Technical Round)

Programming and Coding

Q1. Write code to reverse a string in your preferred programming language.

This program takes an input string, reverses it, and prints the reversed string. It does so by reading the input (x), iterating through its characters in reverse order, and appending them to a new string (reverse_x), effectively reversing it.

Q2. Implement a binary search algorithm and explain its time complexity.

The binary search algorithm works by repeatedly dividing the search space in half. It starts with the entire array and compares the middle element to the target value. Depending on the comparison result, it narrows down the search space to the left or right half and continues this process until the target element is found or the search interval becomes empty.

At any Kth step, our search space would be at most N / (2^k), and ultimately, we are required to find the smallest value of K for which it's no longer possible to make further divisions in our search space. 
N / (2^k) < 1 on taking log on both sides, we get k = log(N) + 1.

The time complexity of binary search is, therefore, O(logN), which is much more efficient than a linear search time complexity of O(N), especially for large values of N.

Q3. When would you use Stack over Queue?

The time complexity of insertion and removal of elements from both stack and queue takes O(1) time but we have differences in the use cases of both these data structures. We prefer to use a stack when we need to keep track of function calls, manage state changes, or reverse a sequence of elements.

Whereas, we prefer to use a queue when we need to manage tasks in a sequential order, handle items in the order they arrive (e.g., in a print queue or task processing system), or perform breadth-first traversal of data structures.

Q4. Explain the concept of recursion and provide an example.

Recursion is a programming concept where a function calls itself in order to solve a problem. The basic idea behind recursion is to keep breaking down a given problem into smaller and smaller problems so as to ultimately reach a point the original problem has been broken down to such an extent that we know the solution of smallest of sub-problems.

Based on the solution to small sub-problems, we keep building the solution for larger problems until the original problem(largest) is solved. Recursion involves two main components: a base case which is the termination condition of the recursion, when met, it stops the recursive calls and returns a value without further recursive calls. and a recursive case in which the function calls itself with modified parameters, moving closer to the base case. The concept of recursion can be understood with the help of a recursive function which calculated factorial of a number.

The factorial function uses recursion to calculate the factorial of a number n. The base case is when n is 0 or 1, in which case the function returns 1. In the recursive case, the function calls itself with n - 1 and multiplies the result by n. This continues until the base case is reached.

Q5. How do you handle null or undefined values in your code to prevent errors?

There are multiple ways by following which we can handle null or undefined values so as to prevent errors. These includes using conditional statements (such as if or switch) to check if a value is null or undefined before attempting to access or manipulate it, providing default fallback values to be used when a variable is null or undefined, using ternary operators to conditionally set a value based on whether a variable is null or undefined, and using try-catch or similar mechanisms to catch exceptions that may arise when working with null or undefined values.

We can also perform type checking to ensure that a value is of the expected type and not null or undefined. We can also use assertions to enforce expectations about values.

Q6. Describe the principles of object-oriented programming and provide an example of inheritance and encapsulation in your code.

The four main principles of OOP includes:

• Encapsulation which focuses on hiding the internal details of an object and providing a controlled interface for interacting with it hence maintaining data integrity and preventing unauthorised access.
• Inheritance which is the mechanism by which one class (subclass or derived class) can inherit the properties and behaviours of another class (super-class or base class) promoting code re-usability and allowing the creation of hierarchies of classes.
• Polymorphism which enables us to write code that can work with objects of multiple types, promoting flexibility and extensibility.
• Abstraction which involves simplifying complex reality by modelling classes based on the essential features and ignoring unnecessary details.

Output: 
Circle's Area: 78.5397
Circle Area: 78.5397

In this example, we have two classes: Shape and Circle. Shape is the base class with an encapsulated area property and methods to set, get, and display the area. Circle is the derived class that inherits from Shape and adds a radius property and a calculateArea method. The displayArea method is overridden in the Circle class to provide a more specific implementation.

Q7. Discuss the differences between synchronous and asynchronous programming.

Synchronous and asynchronous programming are two different approaches to managing the execution of tasks and handling the concurrency in a software execution. In synchronous programming, tasks are executed one after the other in a sequential manner. When a task is being processed, it blocks the execution of the other tasks in queue until it's own execution is completed. 

Whereas in asynchronous programming, tasks can be initiated and executed independently. When a task takes a long time to complete, the program doesn't wait and continues executing other tasks.
Asynchronous code allows for more effective utilisation of CPU resources, as multiple tasks can run concurrently, making it suitable for applications that require high concurrency, such as web servers and real-time applications. Synchronous code on the other hand do not support concurrency but is relatively easy to understand and predict because it follows a straightforward flow of execution.

Q8. How would you handle and validate user input in a web application?

Handling and validating user input in a web application is essential to ensure the security and reliability of our application. Validation can be achieved in following ways:

• We can employ client-side and server-side form validation to catch errors before they reach the server. HTML 5 provides built-in form validation features that can be utilized on the client side.
• Sanitising the user inputs by removing or escaping potentially harmful characters, such as SQL injection, HTML tags, and JavaScript code.
• When interacting with a database we should avoid embedding user inputs into the SQL queries instead we can use parameterised queries or prepared statements to prevent SQL injection attacks.
• We can employ CAPTCHA or other anti-bot techniques to differentiate between human users and automated scripts.

We can also implement security headers in your web application to mitigate certain attacks, such as Content Security Policy (CSP) headers.

Q9. What is your approach to debugging complex code issues?

Complex code issues are unavoidable and integral part of software development tackling which can be challenging. To reduce down efforts and efficiently eliminate issues we can: 

•  Understand the problem and attempt to reproduce it in a controlled environment to identify the specific inputs or conditions that trigger the issue and work accordingly.
• We can isolate the part of code causing the issue by executing different routines individually and disabling all the remaining to identify which block exactly is causing the issue.
• Employ debugging tools provided by your development environment, such as IDEs, debuggers, and profiling tools. Set breakpoints, inspect variables, and dry run through code to understand its execution flow.
• Use version control systems to compare the current code with a previous working version to pinpoint changes that might have introduced the issue.
• Collaborate with a colleague through pair programming to get a fresh perspective on the problem. Sometimes, a second set of eyes can provide valuable insights.

Q10. How can you optimize code performance?

• Code performance can be optimised through several ways:
• Selecting efficient data structures and algorithms according to the need of the problem.
• Minimising input/output operations (e.g., file reads/writes, network requests, database queries) to the best extent as possible as they constitute the slowest part during execution.
• Efficiently minimising the number of iterations and reducing work inside loops. Consider loop unrolling and loop fusion where appropriate.
• Implementing caching mechanisms to store frequently accessed data, reducing the need to recalculate or retrieve data from slower sources.
• Compiled languages tend to be faster than interpreted ones. Considering use of languages that compile to machine code for performance-critical parts of the application.

Data Structures and Algorithms

Q1. Explain the concept of a linked list and its advantages and disadvantages over an array.

A linked list is a data structure that consists of a sequence of nodes where each node contains a value and one/two pointers which points to the adjacent nodes (previous/next). The first element in a linked list is called the head, and the last element typically points to a null reference.

Compared to array, linked lists can grow or shrink in size during runtime, making them suitable for situations where the number of elements is not known in advance. Apart from that insert and delete operations at any position can be done in O(1) time, whereas in an array it takes O(N) time.

A major drawback of linked list is that we cannot access an  element without traversing the entire list up to that element so random access time is O(N) whereas it is O(1) in  case of arrays. Linked list also has poorer cache performance than arrays due to their scattered memory locations.

Q2. What is a hash table and when is it useful in programming?

A hash table, also known as a hash map, is a data structure that provides efficient data retrieval and storage of key-value pairs. It uses a hash function to compute an index into an array of buckets or slots, from which the desired value can be found.

They are useful in programming for near-constant-time (O(1)) average-case complexity for key-value retrieval. This is faster than many other data structures, such as arrays or linked lists, which may require linear search. Hash tables can also quickly insert and delete key-value pairs, often in O(1) time. This is particularly advantageous for dynamic data structures that frequently change in size. 

Q3. Implement a sorting algorithm (e.g., quicksort or mergesort) and analyze its time complexity.

QuickSort is a sorting algorithm that selects a pivot element and organises the array by placing the pivot in its correct sorted position, dividing the array into smaller parts, and recursively sorting them.
Quick sort algorithm can be implemented as follows:

The time complexity of the QuickSort algorithm depends on the choice of the pivot and the distribution of data in the list to be sorted. On an average, it has an O(N * log(N)) time complexity similar to that of MergeSort.

Q4. Describe the difference between a breadth-first search (BFS) and a depth-first search (DFS) algorithm.

Breadth-First Search (BFS) and Depth-First Search (DFS) are both graph traversal algorithms used to explore and search through graph or tree structures. They differ in the strategies for visiting nodes and the order in which they explore the graph. 

BFS explores the graph level by level, starting from the source node (or nodes) and moving outward to nodes at the same level before descending to the next level whereas DFS explores down a branch as far as possible before backtracking to explore other branches. It descends as deep as possible along each branch before backtracking. 

BFS uses a queue data structure to maintain the order of nodes to be explored whereas DFS uses a stack.  Since we are only iterating over the graph’s edges and vertices only once, the time complexity for both algorithms is linear O(V+E).

Q5. What is dynamic programming, and when would you use it?

Dynamic programming is a problem-solving technique that involves avoiding repetitive calculations by storing the result to be used in future. We break down the given problem into multiple sub-problems. We calculate answer for those sub-problems and store their results so as to avoid calculating it again.

Dynamic programming is helpful in case when the given problem has overlapping sub-problems i.e., there are common sub-problems that are solved multiple times and optimal substructure i.e. solution to a larger problem can be constructed from the solutions to its smaller sub-problems.

This technique can be applied to a wide range of problems, which includes Fibonacci Sequence, Shortest Path Problems, Longest Common Subsequence (LCS), Knapsack Problem, Matrix Chain Multiplication etc.

Software Design and Architecture

Q1. Explain the SOLID principles in software design and how they apply to your projects.

SOLID design principles are a set of 5 design principles which includes:

• The Single responsibility principle (S) states that a class should have only one reason to change that is a given class should take only one responsibility.
• The Open/Close principle suggests that software entities (such as classes, modules, or functions) should be open for extension but closed for modification.
• Liskov Substitution Principle (LSP) states that objects of derived class should be able to replace objects of the base class without affecting the correctness of the program.
• The Interface segregation principle encourages creating small, specific interfaces rather than large, general-purpose ones. The basic idea is that clients should not be forced to depend on interfaces they don't use.
• The Dependency inversion principle states that high-level modules should not depend on low-level modules, both should depend on abstractions. Additionally, abstractions should not depend on details rather details should depend on abstractions.

In my project on e-commerce application, separate classes that can handle user authentication, product catalogue management, order processing and payment handling has been made. The product catalogue system is open for extension as new products can be added without altering the core catalogue code.  

Q2. Discuss the concept of design patterns and provide an example of when you've used one.

Design patterns are general solutions to some of the recurring problems in software design. They are basically a blue-print of approach to be followed for solving specific problems in such a way that is both efficient and maintainable. 
Design patterns ensure that the product under design is structured in a clear, understandable and flexible manner making it easier to maintain and allow multiple developers to collaborate while working upon it. They are generally classified into three categories which are Creational patterns which deals with object creation mechanisms that increase flexibility and reuse of existing code, Structural patterns are concerned with how classes and objects are composed to form larger structures while keeping them efficient and flexible and Behavioral Patterns which focuses on communication and assignments of responsibilities between objects.

While working on one of the projects, I encountered a situation where I had to integrate with an external API that had a different interface from what my application expected. I used the adapter pattern (Structural Patterns) to create a wrapper class that translated the external API's interface into one that my application could work with seamlessly.

Q3. How do you handle version control in a team, and what are the benefits of using Git?

In a team setting, handling version control is essential for collaboration, code management, and tracking changes in the project. A central repository for the project is set up on platforms like GitHub, GitLab, or Bitbucket which serves as the master copy of the code. We define a branching strategy , such as Git Flow, where we have different branches for features, bug fixes, development, and release ensuring all the  work is organised and do not interfere with each other.

Developers are able to clone the central repository to their local machines and work on their assigned tasks in feature branches, making regular commits as they make progress. Once a developer finish working on assigned feature or fix, they create a pull request (PR) to merge their changes into the development branch. 

Git is a popular distributed version control system that offers several benefits for team collaboration. It allows every team member to have their local copy of the entire repository. This enables offline work and faster access to version history. It's branching and merging capabilities allows for work on multiple features or bug fixes concurrently and merge them back into a single codebase. It also allows us to track who made changes, when they were made, and what the changes were, which is essential for debugging and auditing.

Q4. What is the difference between monolithic and microservices architectures, and when would you choose one over the other?

Monolithic and Microservices are two different architectural styles for designing and building software applications. Monolithic architecture is a traditional model of a software application where the entire application is developed as a single, tightly integrated codebase and entire application is deployed as a single unit. Any updates or changes require re-deploying the entire application.

Microservices architecture, on the other hand, decomposes the application into a series of independently deployable services, each responsible for a specific business capability.
They can be deployed and updated independently. Changes to one service don't require redeploying the entire application.

Scaling a monolithic application requires replicating the entire application, which can be inefficient and expensive whereas In microservices architecture the services can be individually scaled to handle variable loads, leading to better resource utilisation.

We should opt for microservices architecture when different parts of the application require distinct technologies, databases, or frameworks and we need to handle variable workloads on different sections, which demands the ability to scale individual components independently. 
A monolith is a better choice in cases where a quick development cycle is more important than scalability and long-term maintainability.

Web Development

Q1. Explain the differences between HTTP and HTTPS and the importance of encryption.

HTTP (Hypertext Transfer Protocol) and HTTPS (Hypertext Transfer Protocol Secure) are two protocols which is used for communication between a web client (e.g. a browser) and a web server. The primary basis for distinction between two lies in the level of security they provide in context of data encryption.

HTTP does not provide data encryption or security to the data transferred by default. It is send over in the form of a plain text susceptible to interception by malicious actors. HTTPS on the other hand encrypts the data transferred between the client and server using encryption protocols like TLS (Transport Layer Security) or SSL (Secure Sockets Layer).

Encryption acts like a lock to the data. It makes our private information and messages unreadable to someone who doesn't have the right key to perform decryption, ensuring that even if someone gets hold of our data, they are not able to interpret it and hence prevent the associated misuse.

Q2. Discuss the basics of RESTful API design.

Designing a RESTful API (Representational State Transfer) involves creating a set of rules and conventions for building web services that are scalable, easy to understand, and work seamlessly with HTTP. Some of the basic principles to follow while designing RESTful APIs include:

• RESTful APIs should use JSON (JavaScript Object Notation) as the format for data exchange. JSON is lightweight, human-readable, and widely supported by programming languages and libraries.
• Endpoints should be logically nested to represent relationships between resources. For example, /users/123/orders would retrieve orders for the user with ID 123.
• RESTful endpoints should use nouns to represent resources rather than verbs. For example, instead of /createUser, we should use /users to represent a collection of users.
• API endpoints should handle errors gracefully and provide informative error responses. Standard HTTP status codes like 400 (Bad Request) and 404 (Not Found) should be used to indicate the outcome of the request to the client.
• RESTful APIs should provide query parameters to allow clients to filter, sort, and paginate data. For example, /products?category=electronics&sort=price&limit=10 could be used to retrieve the first 10 electronics products sorted by price.
• Caching can be employed to improve API performance. By setting appropriate caching headers (e.g. Cache-Control), clients and intermediaries can store responses and avoid redundant requests to the server.

Q3. How does a web server handle client requests and serve web pages?

The web server receives the HTTP request from the client and processes it which typically involves identifying the requested resource (e.g. a specific web page or file) and locating it on the server's file system. In some cases, the web server may need to perform server-side processing, such as running server-side scripts or interacting with a database to generate dynamic content. After the request processing is done the web server generates an HTTP response (can be static or dynamic), which includes an HTTP status code, response headers, and the content of the requested web page or resource. The web server sends the HTTP response back to the client over the established TCP connection. The response includes the requested web page's content and metadata. The client receives the HTTP response and parses the response, rendering the web page and any associated resources e.g. images, style sheets, and scripts.

Q4. What is cross-site scripting (XSS), and how can you prevent it in your web applications?

Cross-site scripting (XSS) is a form of cyber-attack in which an attacker injects malicious scripts (usually JavaScript) into web content that is then viewed by other users. The injected scripts run in the client's machine, potentially leading to various security issues, including data theft, session hijacking etc. 
An XSS attack is typically initiated by sending a harmful link to a user and convincing them to click on it. If the application or website doesn't have adequate data sanitation measures in place, the malicious link will execute the attacker's code on the user's system eventually leading to acquisition of user's active session cookies.
For the prevention of XSS in our web application we can employ following methods:

• Input validation must be performed to ensure that it contains only expected and safe data. Any input that looks suspicious, contains HTML or script tags, or exceeds defined limits should be rejected.
• User generated content should be properly encoded before rendering it on web pages. HTML-encode user data to prevent it from being interpreted as code.
• Marking cookies as HTTP-only to prevent client-side scripts from accessing them. This can protect sensitive session data from being stolen.

Databases

Q1. Describe the differences between SQL and NoSQL databases and when would you use each.

SQL (Structured Query Language) and NoSQL (Not Only SQL) databases are two different types of database management systems which differ from each other on the organisation of data.

SQL databases use a structured, tabular format with predefined schemas. Data is organized into tables with rows and columns, and each column has a specific data type.

NoSQL databases do not has the restriction and support a variety of data models, including document, key-value, column-family, and graph. They are schema-flexible and allow storing unstructured or semi-structured data.

SQL databases are designed for vertical scalability whereas NoSQL databases are designed for horizontal scalability, making them well-suited for applications that need to handle large volumes of data and traffic.

We should use SQL databases when the data structure is well defined and is highly unlikely to change frequently but if there's any scope of evolution or there's need for flexibility we should use NoSQL databases. 

Q2. Write a SQL query to retrieve data from a database table.

Let's suppose we have a table named products and where we have three columns denoting the name of the product (product_name), price (price), and the category to which it belongs (category). We can query the database to show all the products along with price which fall under the electronics category.

SELECT product_name, price
FROM products
WHERE category = 'Electronics';

Q3. Explain the concept of database indexing and its benefits.

Database indexing is a database optimisation technique used to enhance the speed and efficiency of data retrieval operations on a database at the cost of additional storage and maintenance overhead. It involves creation of a separate data structure consisting of a set of key-value pairs, with the key being the indexed column(s) and the value being a reference to the row in the table. The index is sorted based on the indexed column(s) which allows for efficient searching and retrieval of data.

Indexes can reduce the number of I/O (Input/Output) operations needed to access data, which can lead to substantial performance improvements, particularly when dealing with large datasets. They can also enforce constraints, such as unique constraints and primary key constraints, which ensure data integrity and accuracy in the database.

System Design

Q1. Can you design a simplified online shopping cart system, including database schema and key components?

A simplified design for an online shopping cart system can have following key components:

• User authentication so that users can create accounts, log in, and manage their profiles.
• Product catalogue for record of products each with a name, description, price, and availability status.
• A Shopping cart where users can add products to their shopping cart, view cart contents, update quantities, and remove items.
• Checkout process to enter shipping and payment information, and complete the purchase.
• View order history to view their order history, track shipments and previous purchases and order details.

Some of the essential table of simplified database schema would include:

1. A user table (user_id (PK), username, password_hash, email, name, address)
2. A product table (product_id (PK), name, description, price, availability_status)
3. A Shopping Cart Table (cart_id (PK), user_id (FK), product_id (FK), quantity)
4. An order table (order_id (Primary Key), user_id (FK), order_date, product_id, quantity, purchase_price)

How would you ensure high availability and fault tolerance in a distributed system?

A highly available and fault tolerance system can be achieved through the following measures:

• Replicating critical components such as load balancers, databases and data across multiple servers or data centres so that if one instance fails, another can take over.
• Implementing load balancers to distribute incoming traffic across multiple servers. Load balancers can detect unhealthy servers and route traffic to healthy ones, ensuring even distribution and fault tolerance.
• Using microservices architecture to isolate components of your system so that if one microservice fails, it won't necessarily affect the entire system. We can also implement the circuit breaker pattern to handle transient failures of a given service.
  
  

Security

Q1. How do you prevent common security vulnerabilities, such as SQL injection and cross-site request forgery (CSRF), in your applications?

Preventing common security vulnerabilities, such as SQL injection and cross-site request forgery (CSRF), is essential to protect our applications from potential attacks. Some of the best practices which eliminates these vulnerabilities includes:

• Employing parameterized queries or prepared statements provided by specific programming language or database framework under use which automatically handles the input data and prevent it from being executed as SQL code.
• Validation of the inputs from the users to ensure that user provided data conforms to the expected formats and does not contain malicious SQL codes.
• Anti-CSRF tokens can be included in the forms which is generated per user session and verified on the server side when form submissions are received.
• Implementing the same origin policy helps to ensure that web pages can only make requests from the same origin from which they were loaded preventing unauthorised requests to other domains.

Q2. Describe the principles of least privilege and how they apply to software security.

The Principle of Least Privilege (POLP) is a fundamental concept in providing security to software applications that revolve around the idea of limiting access rights or permissions of users, processes, or systems to the bare minimum level that is both necessary and sufficient to perform the required task. The goal behind the principle is to minimize potential security risks and limit the impact of security breaches or vulnerabilities.

Along with limited rights, a default deny policy can also be implemented where no access is granted unless explicitly authorized forcing careful consideration of access requests.
Periodic reviews and audits must be conducted to ensure the permissions align with the principle of least privilege and should be changed according to the roles and responsibilities.
