I applied through an employee referral. The process took 2 weeks. I interviewed at Boingo (Dallas, TX) in Feb 2015
Interview
There were three polite telephone interviews followed up with one in-person interview. They flew me into the city to take the interview and put me up in a hotel for the night. It was not adversarial at all.

Question 1
They dove into old projects and work experience that applied to the job that was being applied for. There was no standout "gotcha" questions that were asked.
