I applied for a job at Yelp's Arizona office. My recruiter was based out of San Francisco, though. You could tell from most of her emails that I was just a "case number," rather than an actual person. The main part of the interview were two skype interviews: one with the AZ folks and another with the SF folks. I made it to the final round of the hiring process but did not receive an offer. It took them very long to notify me of this, but it was implicit once I didn't hear back by the expected date.
