Applied online. Heard back from recruiter about 3-4 weeks later. First round is like everyone says, a list of basic/core CS concepts. At the end of that interview, my interviewer told me I passed the first round. Second round was a 45 min skype interview, got asked questions like why Yelp, stuff about my resume, and one tech question. An hour after that interview I got an email saying I passed that round. Final round is 2 45 min skype interviews with some potential managers. SImilar to the second round, they asked some questions about my resume and one tech question. Currently waiting to hear back about status.

First interview purely logistical and HR related, followed by 1 technical interview with a leetcode easy question, then a week later 1 Behavioral Interview followed by technical interview with leetcode medium question back to back. Interviewees were very friendly, encouraging and helpful
