There were 3 rounds of interviews, none of which were elimination rounds.

1. DSA - 45 mins, question: Tree-based
2. DSA - 45 mins, question: Time series-based
3. DSA - 45 mins, question: Substring-based

I attempted all the questions but wasn't able to communicate well. This was my only feedback in every round. I suggest you keep communicating your thoughts with the interviewer, no matter what is going on in your head. Ask questions, and they will help you solve the problem. However, in my second interview, the interviewer was not helping me with the question, even though I asked for help.

Tree-based question.
