I was contacted by their recruiter. Had a 20 min phone interview. Asked about me and my experience in technical support/help desk support. Asked about what ticketing process I've used. I was then sent two tests via email. These test were each 30 min long. 1st test was a psychological test. A statement was given and the answer was one of five ratings from strongly agree to strongly disagree. The second test was on math and learning. I was offered a face 2 face interview at their offices in San Francisco. first thing they gave me was another test. This was much more technical with lots of questions about AD. It took about 30 min. Then an interview with the dept manager and a senior developer. Through out the interview they kept mentioning that their clients were difficult and this was a high stress environment.
