My first interview was way more fun than I expected; they looked at my portfolio and asked me questions about my games, then they asked me to brainstorm a concept for a Megaman style boss with them, the three of us (2 interviewers by the way, lead programmer, lead artist) came up with faucet man, where you hit hot and cold valves to suppress his temperature based attacks. In the end I actually did not get the job because I was still in college, a couple months later I received an email asking if I was still interested... I was. The second interview was with the President, and it was short. I'll always assume the decision to hire me was decided before the I ever walked into the second interview.
