The first-round DSA interview: I had shared optimal solutions to both problems, but I haven't received any update yet. It’s disappointing not to get any feedback, especially after investing time and effort. The interview panel was significantly less experienced than me. The interview is quite basic; you should have solved similar LeetCode questions, else it is highly unlikely you will be able to solve those levels of difficulty questions in forty-five minutes of the interview.

There was one hard and one medium-level string-based question from LeetCode.
