It was through on-campus placements and consisted of one long round. I was grilled on several aspects, starting from DSA questions to project discussions and core CS topics.

The interviewer was calm and friendly. After the interview, I felt that I had learned many new things.

I was first asked a question on DSA which was quite thought-provoking. We discussed all the approaches to the question, starting from brute force to further optimizations based on hashmaps, prefix arrays, and binary search.

Then, a second DSA question followed, which was a very common heap-based interview problem.

Later, I was asked questions on DBMS indexes, types of indexing, the underlying data structures used in them, their advantages, disadvantages, etc.
