Rather rigorous interview. I was impressed. I walked out thinking that I did terribly but just really gave it my best. Having come from a support background it felt like they were simulating the environment that you would be exposed to if they did decide to hire you. Main advice: Be sure to brush up on whatever technologies you put down on your resume. They asked me about a lot of things I've done but there are some things I have not done in a while - this definitely caught me off guard, but it was good because after the interview I went right back and reviewed these things such as unix commands.
