I applied through an employee referral. The process took 3 weeks. I interviewed at Yelp (New York, NY) in Jan 2015
Interview
The process was quick. They definitely made it seem like anybody from any background could get and succeed in this position. They told me that I should expect to be making 55-80 phone calls per day.
Interview questions [1]
Question 1
Role Play that you are leaving a voicemail for somebody who won't return your phone call. Make sure you implement their advice in the second try.
