I applied via Campus Placement and was interviewed in Aug 2024. There were 3 interview rounds.

Round 1 - Coding Test 

55 Questions, 1 Hour, 52 MCQs on Core Computer Fundamentals and 3 Coding Questions

Round 2 - Technical 

(2 Questions)

  • Q1. Variation of Number of Components in a Graph
  • Ans. 

    The number of components in a graph can vary based on the connections between nodes.

    • The number of components in a graph can be determined by counting the number of disconnected subgraphs.

    • For example, a graph with 3 disconnected subgraphs would have 3 components.

    • Adding or removing edges between nodes can change the number of components in a graph.

  • Answered by AI
  • Q2. Minimum number of operations to convert string s1 to s2
  • Ans. 

    Minimum number of operations to convert string s1 to s2 is the Levenshtein distance between the two strings.

    • Use dynamic programming to calculate the Levenshtein distance between the two strings.

    • The operations allowed are insertion, deletion, and substitution of a single character.

    • Example: s1 = 'kitten', s2 = 'sitting'. The minimum number of operations is 3 (substitute 'k' with 's', insert 'g', substitute 'e' with 'i').

  • Q2. Given a BST containing distinct integers, and a number ‘X’, find all pairs of integers in the BST whose sum is equal to ‘X’.
  • Ans. 

    Find pairs of integers in a BST whose sum is equal to a given number.

    • Traverse the BST and store the values in a hash set.

    • For each node, check if (X - node.value) exists in the hash set.

    • If yes, add the pair (node.value, X - node.value) to the result.

    • Continue traversal until all nodes are processed.

Round: Technical Interview
Experience: The interviewer asked me about how my previous round went. After that, he asked me to introduce myself and a brief introduction of the projects that I have done. He first asked me a few questions related to my project. Then he moved on to the data structures part. In this round the interviewer gave me strict time limit for coding the solution on paper for each problem and as soon as I was done coding he gave me 2-3 minutes every time to find errors and debug my code.
Tips: Do not panic even if the interviewer sets time limit while solving problems. If the question is not clear ask the interviewer to explain it again.
