It is a lot easier if you are referred by an employee there. HR does take forever to get back (about 2 months) you are given a written test that you edit on your own, and email back. Once you pass that you come in for an interview (most likely a group interview). Depending on the time of year (holiday or not) you should receive a phone call from HR letting you know within a week or so.

I heard back after submitting my application within about a week, to come in for an interview. I was told to bring a copy of my resume and dress comfortably, no need to be formal. When I arrived for the interview though, I found out that it was a group interview, with about 7 other people. It went well, but throughout the process I found it to be very impersonal, as I felt my answers had to compete with the other interviewees, and it was just overall really uncomfortable.
