I met a recruiter at a career fair, and we hit it off. I was asked a few questions on the spot, and the recruiter seemed satisfied with my answers. We then set up a one-on-one interview on my school's campus.

I met with an engineer for what was a typical 45-minute technical interview. However, the initial non-technical questions section was more protracted than at any other company I had interviewed with. They seemed to really be looking for engineers who know Yelp's product, understand its pain points, and can suggest improvements. The technical question was straightforward and interesting, and I actually learned a few things about Yelp from it.

The interview went well, and I was flown out for a round of on-site interviews soon after. After lunch, I went to their office, and the recruiter showed me around. Their new office is amazing and located right in the center of San Francisco. I had four back-to-back technical interviews. The questions were hard but straightforward. If you know your stuff, you'll figure things out. Again, be prepared to talk about aspects of Yelp that interest you; they'll grill you on why you want to work there and what you'd want to do.

A few days after the on-site interviews, I got a call with an offer.

Other reviews cover what to study for the technical questions pretty well. On top of that, know some things about the product.
