The LeetCode question involved finding the number of permutations of a phone number. Everything was really difficult, but the interviewer was nice. The interview was about an hour long and it was conducted locally.

I only did the written interview, and it was good. I was able to answer one question, but unfortunately, I didn't get to answer the second question in time. The interview is relatively easy, but you must know all the concepts.

There were 3 rounds of interviews. The first round was an introduction and an online test. The second and third rounds were knowledge-based interviews. The fourth round was a meeting with HR. I only went as far as the third round.
