A recruiter reached out to me on linked in. Was very formal during the initial interview, discussed all about the interview process and gave suggestions. Initial round- coding interview, easy leetcode style questions but I could not answer as I was under prepared, the interviewer was very patient, helped me solve it and did not make me feel bad.

Usual Software Engineering interview process. First I had a call with a recruiter to discuss roles. 1 telephonic round.  LC question. It was not straightforward. It was not an usual array or tree question. Basic data structure concepts had to be applied to solve the question. I thought the interview went well. Next round was a virtual onsite interview. I scheduled it after 2 weeks so that I can prepare some more. Recruiter gave an overview about the whole interview process. 2 Coding rounds and 2 System design rounds (1 hour each), Hiring manager round (45 minutes). 1st coding round, question was open ended. I asked a few follow up questions to the interviewer. The interviewer gave an ambiguous response to those questions which led me to solve the problem in a non optimal way. I was not able to come up with a proper logic. When I wrote the code, I missed some edge cases. I messed up this round. I could have done better. System design rounds -- if you are designing APIs for a while and preparing for programming interviews, you should be able to answer the System Design questions. Again the questions were not straightforward questions like Design FB or Twitter. I really enjoyed the System design rounds. They were thought provoking and interviewers were very good. The Last coding round was easy. I was able to come up with an optimal solution fairly quickly. At the end of the interview, I knew I would not get selected because of the 1st coding round. I got the onsite interview results in 2 days. Recruiter gave me good detailed feedback on the interviews. It really helped me to work on those things and get better prepared for other interviews. Looks like it's a very good place to work. I would definitely recommend interviewing here.

Recruiter contacted me and discussed the available positions. Scheduled a 1 hour technical phone screen. This was followed by a full day of onsite interviews at SF head quarters. 4 rounds of interviews + 1 lunch interview
