Recruiter was initially friendly but later was not responsive. Questions were not hard and except for one interviewer that was really not nice the rest of interviewers were smart and nice and enjoyed the interaction. Topics include multi threading and low-level system design, high-level system design, behavioral questions. I really liked they do not include leet-coding and that questions are more related to the job. I definitely got the feeling that company is not respecting your time fully since interview process is super long, including 6 interviews, one of which includes reading a paper ahead and a take home exam, while they are not responsive during the recruiting process. I also got mixed signals, I was told that I will be getting an offer, talked with people in my future team, then later got semi-ghosted and finally was told I was rejected with a very vague reason. Similar thing happened to other people I know. I respect the company is very hot right now but it’s not a justification to not respect the candidates.
