I was reached out to by a campus recruiter and scheduled a Skype interview within a week. The questions were mostly familiar from other Product Management interviews. It began with "tell me a little bit about yourself" and more behavioral questions. Later, the interview moved into more product management-oriented questions with a heavier emphasis than average on knowing Yelp's product inside and out (not just its primary product, but new features that were being tested out, etc.). They also asked a few questions about how the web works when a user visits Yelp's site.
