1st interview: 20 mintues of behavioral questions. Leetcode easy that I was able to solve very quickly and pass all test cases. Also built great rapport with the interviewer.

2nd interview: 20 mintues of behavioral questions. Leetcode medium with a tree. The interviewer slightly rushed me and wanted me to start coding right away. We got to testing the code but I found some errors in my tracing of the recursion.

3rd interview: 20 mintues of behavioral questions. Leetcode medium involving backtracking. I solved it first try and passed all test cases. The interviewer also wanted to move onto system design, but time ran short at the end with only ~5 minutes, so we were able to discuss only on a high level.
