Yelp Software Engineer, Backend interview questions

It began with a Hackerrank assignment which was an easy algorithm question. Then I talked to the recruiter discussing the team and my background. After that I had a behavioral 1 hour interview with one of the team members to understand how fit I am for the team: we discussed two of my previous questions and digged in about what challenged me. After that I had a Panel interview which contained four 45 minutes interviews: First round was a system design folloeing by two algorithm and one behavioral interview. Then after a couple of weekas they contacted me for a quick call with the team manager.
