Coded linked list sorter algorithm using quick sort, divided into three partitions: left (smaller than pivot), medium (equal to pivot), right (larger than pivot)
First did OA and only passed 1/2 questions, where the first one was probably a leetcode medium and the second one was an easy. Then got first round interview, which I havent done yet.

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.
