Round-1 (Online Assessment)

• Platform: HackerRank
• The first round comprised 30 MCQ questions on DSA in 30 minutes.
• Questions on Time Complexity, Output of code snippet, DFS, B+ tree, Graph algorithms, etc

Round-2 (Technical Interview Round-1)

• Platform: Google Meet
• The interview was divided into 3 sections: i) DSA ii) DBMS iii) Node.js

i) DSA

a) Merge Sort

• One of my projects was a sorting visualizer, so he asked me the basic steps of Merge Sort and the principle behind it.
• Then he asked me to share my screen, open an editor of my choice and code the Merge Sort algorithm
• He ran several test cases on the code including zero-length array, single-length array
• Then he asked me to explain the time complexity of the algorithm

b) House Robber II

• He gave me the House Robber II problem statement, and asked me the approach.
• I coded the recursive approach telling him the intuition of why recursion.
• He asked the time complexity of the code.
• He was happy enough, and didn’t proceed towards optimization with memoization

This concluded the first section of the interview

ii) DBMS

• He asked me whether I used MySQL
• Why is indexing used? Write a query to apply indexing on a database.

• Gave a JS code snippet and asked the output
• Asked about Hoisting in JavaScript
• Difference between Synchronous and Asynchronous operations

Round-3 (Technical Interview Round-2)

• Platform: Google Meet + LeetCode Interview Platform
• He asked only 1 DSA problem.
• It was a backtracking problem.
• Link: Closest Dessert Cost
• I had never seen this problem, so faced difficulty solving it.

Verdict: Rejected

Tip: Be prepared with DSA , computer fundamentals and projects, because in placements you require luck+preparation.

Sometimes you are lucky, sometimes you are not but you can always be prepared, so that when you are lucky, you are able to grab that opportunity with your preparation
