I applied online. The process took 6 weeks. I interviewed at X in Nov 2014
Interview
Half a dozen phone interviews then one 4 hour interview with 5 people in 30 minuteish blocks. Not a whole lot more to the process. It did take about a month and a half to schedule and go through all of the phone interviews. People were nice and respectful. Almost all of the phone interviews happened as scheduled.
