All my interviews were pleasant enough and not too rough. First, there was a phone interview to generally make me aware of what I was interviewing for. After that, I was brought in for an interview with a few of their project manager's. I could see how people could get stumped with the questions they ask. There were a bunch of questions about how you handled certain scenarios. Then the final round was an interview with the CEO. And it seemed like he was just there to make sure the other guys didn't screw up. Funny thing was that after three rounds of interviews, they never emailed me again. I never received any information about not getting the job, even after emailing them.
