The interview was pretty straightforward. I had been an intern there already for several months, but they didn't just accept me in. I had a phone interview which lasted about 45 minutes with the hiring manager who was from the east coast. A few days later I had the actual interview.
There were 6 different 1 on 1 interviews which lasted for about a half hour each. I interviewed with an HR person, a manger, a couple engineers, an architect and then a couple analysts together.
It was pretty easy. The only difficult questions were those posed by the architect and even then they were simple. I was surprised because there were a lot of people interviewing me, but none went very in depth. It's possible it was just because the position was an IT Engineer 1 and I had already been performing in that position for a few months though.
