I did several mock interviews, a technical screen, and the final round, which was three technical interviews and a behavioral. I set the timeline for the whole process. Personally, it took four months, but you can go faster if you want.

Fairly straightforward, no tricks or gimmicks or even complicated algorithms. It can be solved using hashmaps and lists, but requires you to know basic runtime complexities and thoroughly evaluate tradeoffs. You kind of drive the design yourself.
