Submitted resume via employee referral. Heard from a recruiter about two weeks later. He scheduled a phone interview with me, which covered basic behavioral questions(Why Yelp, etc.) He then sent me a test on hackerrank, which can be found on here. I then had a Skype interview with an engineer. I came up with an efficient solution quickly, but the interviewer wanted me to code up a different, less efficient way. I made it to the onsite round where I was really underwhelmed. The engineers did not seem like they wanted to be there. One interviewer was clearly zoning out as I struggled to come up with an algorithm to a problem. Each interview is half knowledge-based questions and the other half is dedicated to solving one medium-level difficulty problem, all of which can be found online.
