There were two technical rounds and one HR round, as I was initially selected as a 6-month intern and then converted to a full-time employee. The questions were from tree, DP, and stack and queue.

Difficult interview process. Asked tough algorithm questions. LLD and HLD were quite difficult as well. Please be prepared well before appearing for this interview. Need to prepare and appear again.

It was good. They asked two questions. One was regarding trees, like a binary search tree, and then the second question was related to strings. The trees question was a modification of the lowest common ancestor.
