I appeared for an interview before Mar 2024.

Round 1 - Group Discussion 

The group discussion (GD) round is expected to last 20 minutes. The topics were straightforward and easily comprehensible. The primary focus when participating in the GD should be on English fluency. It is not primarily about how content-rich or intellectually impressive your speech is, but rather about the level of fluency in communication.

Round 2 - Technical 

(1 Question)

  • Q1. Most of the questions will be based on our resume.

Interview Preparation Tips

Interview preparation tips for other job seekers - Concentrate on effective communication and include only the skills and experiences you are truly familiar with in your resume. If you are targeting a specific domain, such as data science or mobility, emphasize that domain and highlight the relevant work you have completed.

I applied via Naukri.com and was interviewed in Jun 2021. There were 4 interview rounds.

Interview Questionnaire 

3 Questions

  • Q1. 1.joins and all basic SQL questions
  • Q2. 2. Oops knowledge advantage but not necessary.
  • Ans. 

    Object-oriented programming (OOP) knowledge is an advantage but not necessary for a data engineer.

    • OOP concepts like inheritance, encapsulation, and polymorphism can be useful in designing data models.

    • OOP languages like Java and Python are commonly used in data engineering.

    • Understanding OOP can help with debugging and maintaining code.

    • However, OOP is not a requirement for data engineering and other programming paradigms

  • Q1. AVL tree balance checking
  • Q2. Median of 2 sorted arrays in O(log N) time complexity and O(1) space complexity
  • Ans. 

    Find median of 2 sorted arrays in O(log N) time complexity and O(1) space complexity

    • Use binary search to find the partition point in both arrays

    • Calculate the median based on the partition point and array sizes

    • Adjust the partition points based on the median value

    • Repeat until the partition points are at the median

    • Handle edge cases such as empty arrays and uneven array sizes

  • Answered by AI
  • Q3. Strings Anagram in O(1) space complexity
  • Ans. 

    Anagram of strings in O(1) space complexity

    • Use a fixed size array of integers to store the frequency of characters in the first string

    • Iterate through the second string and decrement the frequency of each character in the array

    • If all the frequencies are zero, then the strings are anagrams

    • Return true or false accordingly

  • Answered by AI
  • Q4. Level order traversal of a tree using Queue
  • Ans. 

    Level order traversal of a tree using Queue

    • Create a queue and add the root node to it

    • While the queue is not empty, remove the front node and print its value

    • Add the left and right child nodes of the removed node to the queue

    • Repeat until the queue is empty

  • Answered by AI
  • Q5. Reverse level order traversal of a tree using Queue
  • Ans. 

    Reverse level order traversal of a tree using Queue

    • Create a queue and push the root node into it

    • While the queue is not empty, pop the front node and push its children into the queue

    • Add the popped node to a stack

    • Once the queue is empty, pop elements from the stack and print them

  • Answered by AI
  • Q6. BFS and DFS Difference
  • Ans. 

    BFS and DFS are graph traversal algorithms. BFS explores nodes level by level while DFS explores nodes depth by depth.

    • BFS uses a queue while DFS uses a stack or recursion.

    • BFS is optimal for finding shortest path while DFS is optimal for finding a path between two nodes.

    • BFS requires more memory as it stores all the nodes at each level while DFS requires less memory.

    • BFS can be used to find connected components while DFS

  • Answered by AI
  • Q7. OS Concepts – Starvation, Demand Paging, Virtual Memory, Deadlocks
  • Q8. Parenthesis Balance Checking

  • Q10. Find product of each element of an array except that element in O(N) time complexity without using / operation
  • Ans. 

    Find product of each element of an array except that element in O(N) time complexity without using / operation

    • Use prefix and suffix products

    • Multiply prefix and suffix products for each element to get the final product

    • Handle edge cases where array has 0 or 1 element separately

  • Answered by AI
  • Q11. Recursively deleting linked list
  • Ans. 

    Recursively delete a linked list

    • Create a recursive function that takes the head of the linked list as input

    • Base case: if the head is null, return

    • Recursively call the function with the next node as input

    • Delete the current node

  • Answered by AI
  • Q12. Recursively deleting linked list from end
  • Ans. 

    Recursively delete a linked list from the end.

    • Start from the head and recursively traverse to the end of the list.

    • Delete the last node and set the second last node's next pointer to null.

    • Repeat until the entire list is deleted.

    • Use a recursive function to implement the deletion process.

  • Answered by AI
  • Q13. Recursively deleting tree
  • Ans. 

    Recursively delete a tree by deleting all its child nodes and then the parent node.

    • Start from the leaf nodes and delete them first.

    • Then move up to the parent nodes and delete them.

    • Repeat until the root node is deleted.

    • Use post-order traversal to ensure child nodes are deleted before parent nodes.

  • Answered by AI
  • Q14. Recursively deleting from end
  • Ans. 

    Recursively delete elements from the end of an array.

    • Create a recursive function that removes the last element of the array.

  • Q16. Shortest path between 2 points in 2-D space in O(log N) time
  • Ans. 

    There is no known algorithm to find shortest path in 2-D space in O(log N) time.

    • The best known algorithm for finding shortest path in 2-D space is Dijkstra's algorithm which has a time complexity of O(N^2).

    • Other algorithms like A* and Bellman-Ford have better time complexity but still not O(log N).

    • If the points are on a grid, Lee algorithm can be used which has a time complexity of O(N).
