I applied through an employee referral. The process took 4 days. I interviewed at Yelp (Scottsdale, AZ) in Oct 2011
Interview
Phone interview went flawless, asked me to come in the same day for face to face....I did 3, with 3 different people. I was at the office for over 3 hours. Got an offer. Accepted. Got an e-mail the Friday before training stating that they could not offer me the position anymore, no explanation given. BS.
