The process was pretty easy. First thing was applying online. The phone interview came probably a little less than a week after I applied.
The phone interview was pretty standard. Just be yourself and you'll be fine. It really is about getting to know you and getting a feel for your personality.
The in person interview was a few days later. The process was pretty fast. I met three people, and they were all very nice, and had been in the position I was applying for.
Be prepared for mock calls and to sell an item in the room you are in, such as the phone or a piece of paper. (not kidding).
The mock calls are just with the person interviewing you. They pretend to be a business owner, and before you do it, they give you a little coaching, and coach you after you've given it a try.
The best thing to do is be yourself. It's a pretty laud back environment, so if you want more structure and ceremony, Yelp is probably not for you.
Even though it is laid back, dress to impress for your interview, and let them know you take the process seriously.
