the OA had 2 hard leetcode problems .. one was a hard tree problem and the other was a hard graph problem. both of them had to be solved in 1h30mins.

A call with manager followed by 2 45 min interviews. One was a typical leetcode question and the other was a system design question. The system design for me was pretty difficult since I am not used to it but the leetcode interview was easy, The system design interview varies for some. Some people got a simple OOP system design question but I got a real system design question where I had to design a feature.
