Initially, a phone screen, then an online leetcode style technical, then multiple onsite technicals in the San Mateo office. During the interview process, I asked some questions that seemed to raise some red flags. Also, the culture in the office seems quite office. No one spoke to each other and it felt tense. I didn't get the offer, but a few weeks later I met some of the team outside of work to find out two of them who interviewed me quit and a few of them were planning on quitting. Definitely dodged a bullet here.
