Sat in front of a panel of people. Asked typical questions. It lasted about an hour. Follow up and everything was done through email. good follow-up and nice response time so as not to linger and let me wonder what was going on. They're always very transparent as to what the next steps were.

Scheduled an interview after submitting my resume, interview consisted of a panel of their engineers asking me about my background and a few technical questions, then was given a written test consisting for general networking and security related questions.
