Epic Technical Service interview questions

Gave my resume to the rep. at the career fair. A week later received an e-mail with a link to a personality test. There were several IQ questions and some situation/response questions. In another had a tel. interview. Pretty easy going, general questions about who I am and what I do. Half of the time they talked about the benefits they provide for their employees. In two weeks I was invited to their site in Wisconsin. Big property. I had another IQ test and some writing/grammar test. Not a problem. Next, was the programming test. There were four tasks. Could choose any programming language.

Career fair -> phone interview -> on-site interview -> offer. They seem to look for everyone with a technical/math background... even candidates that are out of their league as far as their salary levels go (60-70k, unless perhaps you have a programming background). A PhD in my field (decent industry demand) is more like >90k, yet they walked me through the whole process and didn't mention the expected salary until the last HR part. The phone interview is low stress, and most of the on-site interview is just testing (some programming involved) and/or showing off the facilities... the interview did not involve much stress or many typical interview questions.
