Question 1
1st OA questions was I think a search problem and 2nd OA question was a dp problem.
First round 45 mins total with short behavior and technical. I had one question, which was a class design question using heap. Solved question in time but did not hear back.
OA, one technical round, technical superday (3 interviews), leadership call rounds (mix of technical and behavioral qs, typically 2 ro more calls). did not pass the leadership round, very high variance.
