I applied through a staffing agency. The process took 1 week.
The interview consisted of multiple rounds, I guess. The first was the coding round, where two questions were asked. It lasted for 45 minutes. I did give my best to solve it, though, and the optimizing was a follow-up question.
They asked me a LeetCode question of creating the pow(x, n) function. They also followed up on how you will try to optimise it.
