There were 3 phone interviews. First two were batched together. After that they scheduled a third interview. First interview was fairly simple. Was asked to reverse a string and consider all corner cases. And a lot of OS questions were asked like, 'come up with an efficient way to handle fragmentation in main memory'. Second interview, i was asked one question 'Print common elements between two arrays' and eventually was questioned in depth about hash tables and collisions. In third interview, was asked to implement a stack with Constant time min(stack) fetch in addition to pop and push.

One online assessment and one virtual interview included a coding round and leadership principle questions; overall, the process was fairly straightforward and not overly challenging for me throughout the experience.
