I applied through a recruiter, and the process took four weeks.

It is extremely impersonal. You never get to speak or interact with anyone. You go through an internal app where you can complete a bunch of tasks, and it can take weeks to go through the whole process. Most of it was LeetCode-like material and a load of behavioral questions. You get rejected with the standard HR email. They offered to send feedback. When I asked for it, I got some AI junk. It's very likely that their whole hiring process is AI-based.

They make you sign an NDA and try to remove your review if you tell anything. Essentially, it is a medium-level LeetCode question.
