Phone interview - easy
Personality/Skills tests - easy.
Got offer to fly to Madison, WI.
Flew there for 2 days, 1 night
On the day I was there, an employee took us to dinner.
Then the next day about 50+ prospectives were herded to HQ for 2-3 interviews, 1 case study (just behavioral, no math), 1 presentation, info sessions. I did badly on the 10-min presentation I think, which had 3 people watching. One guy just smirked at me the whole time. Then the HR person took me to her office to ask a series of trick/behavior questions.
Followed up promptly in 2 weeks and told me I was rejected :\
Pros: followed up fast, nice campus, good food
Cons: taxi driver said Epic brings in 50+ people to interview A DAY 5 days/wk (seems more like herding cattle), rather tedious interview process....:P...a lot of work to miss 3 days of class, presentation prep....
