Technical Flipkart Interview Questions

Now that we have an idea about what the recruitment process entails, let's have a look at some of the top Flipkart interview questions that will test your technical knowledge and domain expertise.

Q1. What do you mean by Data Structures and Algorithms?

Data Structures are used to store and organize data in a specific and efficient manner, such as arrays, linked lists, trees, graphs, etc. At the same time, algorithms are sets of instructions used to manipulate the data stored in these structures, such as sorting, searching, dynamic programming, and graph algorithms. The combination of data structures and algorithms forms the foundation of computer science and software engineering.

Q2. How does one develop scalable and highly available systems? 

Developing scalable and highly available systems involves defining requirements, choosing suitable technology, implementing load balancing, disaster recovery, monitoring, and continuous testing. Utilize tools such as cloud-based solutions, container orchestration, and microservices architecture to achieve horizontal scaling. Ensure system reliability by implementing redundancy and failover, monitoring performance, and logging.

Q3. How does one ensure the performance of code and identify bottlenecks in the system? 

This is one of the most common Flipkart interview questions you will come across. The answer to this question should be as given below:

Ensuring code performance and identifying bottlenecks involves monitoring system performance, using profiling tools, load testing, visualization, code optimization, and employing caching techniques. There is a need to continuously collect performance data and use it to refine the system for maximum efficiency.

Q4. How can you develop RESTful APIs and microservices architecture?

Developing RESTful APIs and microservices architecture requires a clear understanding of the API requirements and the business problem they are trying to solve. One should start by defining the endpoints, HTTP methods, and data structures, then choose a suitable technology stack such as Django, Flask, Express, etc. and implement the API using best practices for security, performance, and scalability. It is also important to consider using API gateways, service discovery, and containerization technologies such as Docker to manage the deployment and scaling of microservices. Additionally, it's critical to thoroughly test APIs and microservices and implement monitoring and logging to ensure proper functioning in production.

Q5. What kind of database and data storage solutions are preferable in today's market?

One must have hands-on experience in working with various databases such as MySQL, Oracle, and NoSQL databases such as MongoDB, Cassandra, etc. They should know how to design and implement efficient data storage solutions, such as indexing, denormalization, and data partitioning, to improve the performance of database queries. It would be of great advantage if one also has experience in data migration and integrating databases with various applications.

Given the nature of Flipkart's business, you must have good knowledge of DBMS topics and must give a clear and crisp answer to such Flipkart interview questions, just as you can see above.

Q6. What are the differences between partition tolerance, availability, and consistency in a distributed system?

In a distributed system, these are the three most important properties of a system, collectively known as the CAP theorem.

1. Consistency refers to the property that all nodes in the system see the same data at the same time. It ensures that every read request to the system returns the latest write.
2. Availability refers to the property that every request to the system receives a response without a guarantee that it contains the latest version of the data.
3. Partition tolerance refers to the property that the system continues to function even when network partitions occur, meaning that communication between nodes is lost.

The CAP theorem states that it is impossible for a distributed system to guarantee all three of these properties at the same time. The system has to make a trade-off between consistency, availability, and partition tolerance.

Q7. How does a load balancer in a web application function?

A load balancer is a component in a web application architecture that distributes incoming traffic across multiple servers to ensure that no single server becomes overwhelmed. The load balancer operates at the network layer and acts as a reverse proxy, forwarding incoming requests to one of the available servers. The load balancer uses various algorithms, such as round-robin, least connections, and IP hash, to determine which server to forward the request to.

When a server becomes unavailable, the load balancer detects it and removes it from the list of available servers. The load balancer also monitors the health of the servers and adds them back to the list of available servers once they are back up.

Q8. Why are relational database indexes important and how do they work?

The relational database (RDBMS) is an important topic that frequently features in Flipkart interview questions that you must prepare for before appearing for an interview at the company. The answer to the question is-

An index in a relational database is a data structure that stores a mapping of values to the rows in a table. The purpose of an index is to improve the performance of database queries. When a query is executed, the database engine uses the index to quickly locate the rows that match the query conditions. This is faster than scanning the entire table because the index only contains the values that are relevant to the query. There are several types of indexes, including B-tree, hash, and bitmap indexes. B-tree indexes are the most common and provide efficient access to both the range queries.

Indexes are important because they can significantly improve the performance of database queries. However, it is important to note that adding too many indices or indexes on the wrong columns can actually slow down the performance of the database.

Q9. What does the SSL/TLS protocol do to secure web communication, and can you explain how it works?

SSL/TLS is a protocol that encrypts data transmitted between a web server and a browser to prevent eavesdropping and tampering. The SSL/TLS handshake establishes a secure connection by exchanging "hello" messages, verifying the server's certificate, encrypting a symmetric key using the server's public key, and decrypting the key using the server's private key.

As you must know, another important topic for SDE profile applicants is data structures and algorithms (DSA). You will find many Flipkart interview questions circling this topic of study, some of which are given ahead. 

Q10. What is the difference between a depth-first and a breadth-first search algorithm?

Both depth-first search (DFS) and breadth-first search (BFS) are algorithms for traversing and searching a graph. DFS visits all the vertices of a sub-tree before moving to the next sub-tree, while BFS visits all the vertices at a given level before moving to the next level. DFS uses a stack data structure, while BFS uses a queue data structure. DFS is used for finding paths, and cycles, and visiting all vertices in a graph, while BFS is used for finding the shortest path in an unweighted graph.

Q11. What is a greedy algorithm, and give an example?

A greedy algorithm is an algorithm that makes the locally optimal choice at each stage in order to find the global optimum solution. Greedy algorithms are used to solve optimization problems, where a solution is built incrementally by choosing the best option at each step. An example of a greedy algorithm is the activity selection problem, where the algorithm chooses the next activity to perform based on the start time and finish time of the activities.

Q12. What is dynamic programming and give an example?

Dynamic programming is a technique used for solving problems by breaking them down into smaller sub-problems and solving each sub-problem only once. The results of the sub-problems are stored in a table for use in constructing a solution to the original problem. An example of a dynamic programming problem is the knapsack problem, where the algorithm determines the maximum total weight of items that can be included in a knapsack.

Q13. What is a heap data structure and how is it used?

A heap is a complete binary tree data structure where the parent node is either greater than or equal to (max heap) or less than or equal to (min-heap) its children. Heaps are commonly used in implementing priority queues, where elements with the highest or lowest priority are dequeued first. Heaps are also used for sorting, implementing Dijkstra's algorithm for finding the shortest path, and constructing Huffman trees for data compression.

Q14. What is the difference between a hash map and a hash table?

A hash map and a hash table are two names for the same data structure- an array-based implementation of a map from keys to values. The hash function maps each key to an index in an array, where the corresponding value can be found or stored. Both terms are used interchangeably, although the term hash map is more commonly used in modern programming languages such as Java. The key difference between a hash map and other data structures such as arrays or linked lists is the use of the hash function to efficiently locate a value based on its key.

Q15. Can you explain the difference between a stack and a queue data structure?

A stack and a queue are both linear data structures that store elements. A stack operates on the last-in, first-out (LIFO) principle, where the most recently added element is the first to be removed. A queue operates on the first-in, first-out (FIFO) principle, where the first element added is the first to be removed. Stacks are commonly used for implementing undo operations, checking for balanced parentheses, and evaluating postfix expressions. Queues are used for scheduling tasks and handling resource allocation, such as in computer systems and network communication protocols.

Q16. What distinguishes a process from a thread?

The answer to this Flipkart interview question is as follows-

A process is an instance of a running program that has its own memory space, while a thread is a lightweight, independent unit of execution within a process. Multiple threads within a process can share the same memory space, file descriptors, and other resources, but each thread has its own stack and program counter. Threads are used to increase the responsiveness of an application by allowing multiple tasks to be executed simultaneously, while processes are used for isolation, security, and resource management.

Q17. Can you explain the difference between a deadlock and a livelock?

A deadlock occurs in a system when two or more processes are blocked, each waiting for the other to release a resource. This creates a circular waiting situation where none of the processes can continue. A livelock is similar, but instead of blocking, the processes continuously change their state in response to the other processes, without making progress. 

For example, two processes may be trying to acquire locks in the opposite order, and continuously releasing and acquiring locks without making progress. Deadlocks can be resolved by releasing resources, while livelocks cannot be resolved without external intervention.

Q18. Explain the difference between a symmetric and an asymmetric encryption algorithm.

Symmetric encryption algorithms use the same key for both encryption and decryption, while asymmetric encryption algorithms use different keys for encryption and decryption. Symmetric algorithms are faster but less secure, as the same key must be shared among the communicating parties. Asymmetric algorithms, also known as public key cryptography, are slower but more secure, as a public key can be used for encryption and a private key for decryption. Asymmetric algorithms are commonly used for secure communication and digital signatures, while symmetric algorithms are used for bulk data encryption.

Q19. What distinguishes a static website from a dynamic website?

A static website consists of fixed HTML pages that are displayed to the user exactly as stored on the server. A dynamic website generates the content of the page in real-time, based on user inputs and server-side processing. Dynamic websites use technologies such as PHP, Ruby on Rails, and ASP.NET, while static websites are simply HTML files. Static websites are faster, simpler, and easier to develop, while dynamic websites are more flexible and can provide a more interactive user experience.

As a software developer, you will work with many programming languages that Flipkart employs in its operations. It is only natural then, for an interviewer to ask you programming language-based Flipkart interview questions to test your knowledge. Some such questions are:

Q20. What is the difference between deep and shallow copying in Python?

Shallow copying in Python creates a new object, but the object's references to the underlying objects remain the same. On the other hand, deep copying in Python creates a new object and a new instance of the underlying objects so that the two objects are completely independent. Shallow copying can lead to unexpected results when the underlying objects are mutable, whereas deep copying eliminates this issue.

Q21. How do you perform multithreading in Python?

Multi-threading in Python can be achieved using the threading module. The module provides a simple and consistent interface to create and manage threads. To start a new thread, you can create a new instance of the Thread class, passing the function you want to run as a thread as an argument. The start() method can be used to start the thread, and the join() method can be used to wait for the thread to finish.

Q22. What is the difference between the map and filter functions in Python?

The map function in Python takes a function and an iterable as arguments and returns a new iterable with the results of applying the function to each element in the original iterable. The filter function, on the other hand, takes a function and an iterable as arguments and returns a new iterable with the elements for which the function returns True. In other words, the filter function is used to filter elements from an iterable based on a certain condition.

    int data;

    Node next;

    Node(int data) {

        this.data = data;

        this.next = null;

    }

}

class LinkedList {

    Node head;

    public LinkedList(Node head) {

        this.head = head;

    }

    public void reverse() {

        Node prev = null;

        Node current = head;

        Node next = null;

        while (current != null) {

            next = current.next;

            current.next = prev;

            prev = current;

            current = next;

        }

        head = prev;

    }

}

Output:

5 4 3 2 1

Q24. Write a program in Python to implement the Binary Search algorithm.

The input code for this common Flipkart interview questions is-

rr = [1, 3, 5, 7, 9]

x = 5

def binary_search(arr, x):

    low = 0

    high = len(arr) - 1

    while low <= high:

        mid = (low + high) // 2

        if arr[mid] == x:

            return mid

        elif arr[mid] < x:

            low = mid + 1

        else:

            high = mid - 1

    return -1

 Output: 2

Q25. Can you write a program in C++ to find the maximum subarray sum using Kadane's algorithm? 

Input: [-2, 1, -3, 4, -1, 2, 1, -5, 4]

#include <iostream>

#include <vector>




int kadane(std::vector<int>& nums) {

    int max_sum = nums[0], cur_sum = nums[0];

    for (int i = 1; i < nums.size(); i++) {

        cur_sum = std::max(nums[i], cur_sum + nums[i]);

        max_sum = std::max(max_sum, cur_sum);

    }

    return max_sum;

}




int main() {

    std::vector<int> nums = {-2, 1, -3, 4, -1, 2, 1, -5, 4};

    std::cout << "Max subarray sum: " << kadane(nums) << std::endl;

    return 0;

}

Output: Max subarray sum: 6

Q26. Write a Python function to implement a breadth-first search algorithm for a tree data structure.

We can implement a breadth-first search algorithm for a tree data structure using a queue. Here's an example implementation that you can use to answer this Flipkart interview question:

def breadth_first_search(root):

    queue = [root]

    while queue:

        node = queue.pop(0)

        print(node.value)

        if node.left:

            queue.append(node.left)

        if node.right:

            queue.append(node.right)

Q27. Can you write a program in JavaScript to check if a given string is a palindrome?

nput1: "racecar"

Input2: "hello"

function isPalindrome(str) {

    let i = 0, j = str.length - 1;

    while (i < j) {

        if (str[i++] !== str[j--]) {

            return false;

        }

    }

    return true;

}

Input: "racecar"
Output: true

Input: "hello"
Output: false

Q28. Write a Python function to find the common elements between two lists.

There are several ways to find the common elements between two lists. One simple way is to use the intersection() method from the set data structure. Here's an example implementation:

def common_elements(list1, list2):

set1 = set(list1)
set2 = set(list2)
return list(set1.intersection(set2))

Q29. Write a function in Python to find the two numbers in a list that sum to a target value, and provide the output for the list [1, 2, 3, 4, 5] and target value 5.

def two_sum(nums, target):

    num_map = {}

    for i, num in enumerate(nums):

        if target - num in num_map:

            return [num_map[target - num], i]

        num_map[num] = i

    return None




nums = [1, 2, 3, 4, 5]

target = 5

result = two_sum(nums, target)

print(result)

Output: [2, 3]

Q30. Write a function in Python to find the longest common prefix of a list of strings, and provide the output for the list of strings ['apple', 'application', 'apply'].

def longest_common_prefix(strs):

    if not strs:

        return ""

    if len(strs) == 1:

        return strs[0]

    strs.sort()

    prefix = ""

    for i in range(len(strs[0])):

        if strs[0][i] == strs[-1][i]:

            prefix += strs[0][i]

        else:

            break

    return prefix




strs = ['apple', 'application', 'apply']

result = longest_common_prefix(strs)

print(result)

Output: 'app'

Q31. How would you implement Dijkstra's shortest path algorithm for a weighted graph in Python?

import heapq

def dijkstra(graph, start):

    distances = {vertex: float('infinity') for vertex in graph}

    distances[start] = 0

    queue = [(0, start)]

    while queue:

        (distance, current) = heapq.heappop(queue)

        if distance > distances[current]:

            continue

        for neighbor, weight in graph[current].items():

            new_distance = distance + weight

            if new_distance < distances[neighbor]:

                distances[neighbor] = new_distance

                heapq.heappush(queue, (new_distance, neighbor))

    return distances




graph = {

    'A': {'B': 1, 'C': 4},

    'B': {'A': 1, 'C': 2, 'D': 5},

    'C': {'A': 4, 'B': 2, 'D': 1},

    'D': {'B': 5, 'C': 1},

}

print(dijkstra(graph, 'A'))

The output you will receive after running the code solution for the above-mentioned Flipkart interview question is- 

Output: {'A': 0, 'B': 1, 'C': 2, 'D': 3}

Q32. How would you find the first non-repeated character in a string in Python?

def first_non_repeated(s):

    char_count = {}

    for char in s:

        if char in char_count:

            char_count[char] += 1

        else:

            char_count[char] = 1

    for char in s:

        if char_count[char] == 1:

            return char

    return None




print(first_non_repeated("abcab"))

 Output: 'c'

Q33. Write a program to solve the following Gas Station problem-

Given integer arrays A and B, each of size N. There are N gas stations present along a circular route. The amount of gas at station i is A[i]. Suppose your car has an unlimited gas tank. Given the cost of gas to travel from station i to the next station (i+1) is B[i]. If you begin the journey from one of the gas stations with an empty tank, return the minimum starting index of the gas station when you can travel around the circuit once; else, return -1. Starting at i and ending up at the same completes the circuit.

Assume that you can only travel in one direction, i.e., i to i+1, i+2, ... n-1, 0, 1, 2. 
Input Format:
The first argument given is the integer array A. 
The second argument given is the integer array B.
Output Format:
Return the minimum starting index of the gas station when you can travel around the circuit once; else, return -1.

Gas station and candy problems are two of the most common problem types that you will come across when interviewing for SDE profiles across companies, so be prepared. The steps involved in finding the solution for the gas station problem stated in the Flipkart interview question above, are (note that we will use two pointers to solve the problem):

1. Initialize two variables start and end to 0.
2. Calculate the current_gas by adding the gas at the current station to the current_gas and subtracting the cost of gas to travel from the current station to the next station.
3. If current_gas is less than 0, this means that starting from start is not a viable option. So, set start to the next station and reset current_gas to 0.
4. Repeat steps 2 and 3 until end is equal to start or end is one station before start.
5. If end is equal to start, this means that starting from start is a viable option and you can travel around the circuit once. Return start.
6. If end is one station before start, this means that it is not possible to travel around the circuit once. Return -1.

Q34. Write a code to solve the following problem-

Given N children are standing in a line, and each is assigned a rating value. You are supposed to distribute candies to these children as follows:

Each child must get at least one candy.
Children who are assigned a higher rating get more candies than their neighbors.
Determine the minimum candies to be given. 

Input Format: 
The first and the only argument contains N integers in an array A.

Output Format:
Return an integer that represents the minimum candies to be given.

It is important to note that you will have to use two passes to find the right solution for this technical Flipkart interview question. The answer is-

1. Initialize an array candies of size N with all elements set to 1. This represents the minimum number of candies each child must get.
2. Start from the left side of the array and update candies[i] to candies[i] = max(candies[i], candies[i - 1] + 1) if rating[i] > rating[i - 1]. This ensures that children with higher ratings get more candies than their neighbors.
3. Start from the right side of the array and update candies[i] to candies[i] = max(candies[i], candies[i + 1] + 1) if rating[i] > rating[i + 1]. This step is necessary because the first step only takes care of the increasing order, but there might be situations where the ratings are in decreasing order.
4. Return the sum of all elements in the candies array.

Q35. Write a code to solve the problem-

Min Sum Path in Matrix

For a given 2D integer array A of size M x N, find a path from the top left to the bottom right that minimizes the sum of all numbers. (Note: You are only allowed to move either down or right at any time.)
Input Format- The first and only argument is a 2D integer array A of size M x N.
Output Format- Return a single integer that denotes the minimum sum of a path from the cell (1, 1) to cell (M, N).

The answer is-

1. Initialize a 2D array dp of size M x N with all elements set to 0.
2. Set the first element of the first row of the dp array to the first element of the first row of the input array A.
3. For each subsequent element in the first row, set dp[0][i] = dp[0][i - 1] + A[0][i].
4. Set the first element of the first column of the dp array to the first element of the first column of the input array A.
5. For each subsequent element in the first column, set dp[i][0] = dp[i - 1][0] + A[i][0].
6. For each subsequent element in the dp array, set dp[i][j] = min(dp[i - 1][j], dp[i][j - 1]) + A[i][j].
7. Return the last element in the last row of the dp array.

Q36. Merge K Sorted Lists as follows-

Merge the given k sorted linked lists. Return the sorted lists as one sorted list. For Example :

The lists are: 
1 -> 10 -> 20
4 -> 11 -> 13
3 -> 8 -> 9 

They will result in the following list:
1 -> 3 -> 4 -> 8 -> 9 -> 10 -> 11 -> 13 -> 20

You can solve this question using the Divide and Conquer approach. First, create an array lists of linked lists.

While the number of linked lists in the lists array is greater than 1:

• If the value of the node pointed to by lists[left] is less than or equal to the value of the node pointed to by lists[right], append the node pointed to by lists[left] to the merged linked list and increment left.
• If the value of the node pointed to by lists[right] is less than the value of the node pointed to by lists[left], append the node pointed to by lists[right] to the merged linked list and increment right.
• Initialize two pointers, left and right, to 0 and 1, respectively.
• Create a new linked list merged and initialize the head to None.
• While left is less than the length of the lists array and right is less than the length of the lists array:
• If left is less than the length of the lists array, append the remaining elements of the linked list pointed to by lists[left] to the merged linked list.
• If right is less than the length of the lists array, append the remaining elements of the linked list pointed to by lists[right] to the merged linked list.
• Replace the lists array with an array containing the merged linked list.
• Return the first element of the lists array.

Q37. Write the code for the following:

First Non-Repeating Character in a Stream of Characters
For a given string A that denotes a stream of lowercase alphabets, make a new string B to find the first non-repeating character every time a character is inserted into the stream and append it at the end to B. If no non-repeating character is discovered, append '#' at the end of B.
Problem Constraints
1 <= length of the string <= 100000
Input Format- The only argument given is string A.
Output Format- Return a string B on processing the string of lowercase alphabets A.

One approach to solve this problem is to use two data structures- a queue and a hash table.

1. Initialize an empty queue and a hash table.
2. Iterate through the characters in the given string A.
3. For each character, check if it's in the hash table.

1. If the character is not in the hash table, add it to the hash table and enqueue it into the queue.
2. If the character is in the hash table, remove it from the queue and update the value in the hash table.

1. Dequeue the first character from the queue and append it to the output string B if the value in the hash table for this character is 1. If the queue is empty, append '#' to the output string B.
2. Repeat steps 2 to 4 for each character in A.

This solution has a time complexity of O(n) and a space complexity of O(1), where n is the length of the string A.

Tip- You will be given a limited amount of time to provide answers to these Flipkart interview questions. It is hence important o sharpen your time management skills. For this, you must practice as many sample questions as you can before you appear for the actual interview.

Q38. Write a code for the following:

Meeting Rooms

For a given 2D integer array A of size N x 2 that denotes time intervals of different meetings, find the minimum number of conference rooms needed for all meetings, where:

A[i][0] = start time of the ith meeting
A[i][1] = end time of the ith meeting
Problem Constraints
1 <= N <= 10
0 <= A[i][0] < A[i][1] <= 2 * 109
Input Format- The only argument given is the matrix A.
Output Format- Return the minimum number of conference rooms needed for all the meetings.

The answer must consist of the following steps:

1. Sort the array of time intervals based on the start time of each meeting:
• This will ensure that you are processing the meetings in the order in which they start.
2. Initialize variable rooms to keep track of the number of conference rooms required.
3. Initialize a priority queue to track the end times of the meetings in progress:
• This is because you want to keep track of the end times of all the ongoing meetings to determine if a new meeting can take place in the same room or if you need to allocate a new room.
4. For each time interval, compare the start time of the current meeting with the end time of the meeting with the earliest end time in the priority queue:
• If the start time of the current meeting is greater than or equal to the end time of the meeting with the earliest end time, remove that meeting from the priority queue.
• If the start time of the current meeting is less than the end time of the meeting with the earliest end time, allocate a new room by incrementing the rooms variable and adding the end time of the current meeting to the priority queue.
5. Repeat this process for all time intervals and return the value of rooms as the final result.
