In general interview process was very smooth with great communication. There was a technical round interview as well as a SIG interview which was essentially behavioral and past experience-based. Positive experience all around.

One hour technical interview with a coding exercise. Two staff level engineers conducted the interview. After about 40 minutes discussing my resume and me trying to ask questions about the position, but not getting much in the way of a response, there was a 20 minute coding exercise. During this exercise I spent about 15 minutes discussing how I would design the code and was left with only 5 minutes to write code. The interviewers did not engage in much back and forth or discussion and seemed to be just silently waiting for me to finish, except for one point when I asked for feedback and one of the interviewers smirked and just said I had a mistake in the code I had started to write. At the end of the exercise I rang off the interview as soon as possible as it seemed like a situation where the interviewers were hostile and I got the impression that nothing I did would have resulted in success.

3 levels of Interview is minimum for the Staff Engineer Role. 1. Technical Pairing Interview. 2. Behavioral Interview with 2 Leads. 3. Final Round with Manager Sometimes Principal Engineers will take another round of interview
