I applied through a referral and received a coding test link. This test included two coding problems and some reasoning questions.

After that, I proceeded to the first technical round. In this round, the interviewer presented three DSA problems, all of which I solved.

On the same day, I received a call from HR regarding my second round. During this round, the interviewer asked two DSA problems, and we also discussed my projects.

1. OA: There were 2 coding problems and reasoning given.

2. In my first technical round, the interviewer asked me to introduce myself. Then, they asked the first DSA problem: generate all balanced parentheses strings of size N.

The second question was: find the max element of every K-sized window in an array.

The third question was: bottom level view of a tree.

1. In the second round of the technical interview, the interviewer first asked me for an introduction and then about the projects I've created, the issues I've faced, how I resolved them, and what I learned from that. After that, we directly moved forward with DSA questions.

The first question was about prefix sum and queries.

The second question was finding the LCA in a binary tree.
