I was referred for the Account Executive position by a friend who worked at Yelp. There was an initial phone interview with basic sales questions. They asked things like "what motivates you?" "why do you want to go into sales?" and "why yelp and what you knew about the position?" I was asked to come into the office for an in person interview. I was interviewed by three different sales managers with different styles. Each had me do a mock sales exercise. Be prepared to sell their advertising and to overcome obstacles like someone who wants to advertise in the yellow pages instead or who doesn't have money to spend on the advertising program. They want you to be quick, persistent and outgoing. The last manager asked me to sell him my favorite product. Overall a pretty easy interview process. I realized after the interview that sales isn't for me.
