I applied through university. The process took 2+ months. I interviewed at Yelp in Nov 2016
Interview
I interviewed for a backend/infra position.
Spoke to an engineer at a career fair and got a coding challenge a few days later(also attended a tech talk on campus and spoke with the same engineer there). From there I did a phone screen on Skype. The final round was 2 back to back Skype calls. I received a phone call after a few weeks with an offer. The whole process took about 2 months and 3 days from coding challenge to offer letter.
Overall I was very upset with the recruitment process from Yelp and expected much more from the company. It took 5 weeks to schedule my first interview(I sent 4 followup emails during this time and had to give more availability because they couldnt schedule in the 4 weeks I originally provided). By the time it came to my first interview I had to schedule them around my finals week because the process had been drawn out so long. The process took 61 days from coding challenge to offer.
I was able to complete a coding challenge, 3 interviews, and receive an offer call in the same timeline for a different company than it took to complete my first interview with Yelp from time of completing the coding challenge.
From my experience talking to other students at my school several other students felt the same frustration as I did when dealing with the recruiter. A common advice from several others was to just contact another recruiter to get an interview scheduled.

Interview
I applied for a role in the infrastructure team.
I was contacted by a recruiter to do a 15 minute hacker rank. The problem description was long, so be careful and make sure you understand it.
Following that, I had a 45 minute technical interview with an engineer. We talked about Yelp, my background, and he asked some general questions about scaling. I then answered a technical question on a live coding link. Following this stage, I had 2 final 45 minute interviews with an engineering manager and an engineer that were similar in format. Two weeks later, I got an offer.

Pleasant Interview, the guy mentioned a couple of things about the company, talked about my projects, and asked me about some specifics. Asked about some technical knowledge and then went on to the technical question. Then there was another guy to do the behavioral interview, talked about the position itself and some of the things about yelp.

Interview
I applied for the data mining position. Started with a Hackerrank challenge. Then a Skype screen (45 minutes, talked about resume, NLP related questions about categorizing reviews and did a coding question). Finally two back to back 45 minute long Skype interviews, same as the phone screen.
The process took quite a while with some difficulty with availability initially. However the recruiters were always flexible with rescheduling.

Question 1
If restaurant categories have integer IDs and some can be marked as duplicates of others, design a library to store and retrieve such duplicate sets. If you query an ID it should return the smallest duplicate. You should be able to mark duplicates etc.
