The interview process was quite lengthy. After applying, it took about a month to receive an invite for a nearly 3-hour Online Assessment which included two coding problems (70 minutes), work simulations, and work style questions. About a month later, I received the VO survey, followed by scheduling the virtual onsite interview. This round consisted of three one-hour interviews, all in a single day.

One of them was an innovative dynamic programming problem, which was tougher than what I had anticipated based on others' experiences.
