I'm pretty sure if you get invited on-site to interview with them there's a good chance you'll get an offer. It's really more for them to sell you on their campus, their culture, and on Madison. Especially since the pre-screening before you come on-site is so extensive. Most of the day consists of tours, interviews to determine culture fit, and you might have a case study or two for each role you're applying for as well. Also, quite odd but they'll also ask you to sit at a computer and take a grammar test..... not really sure why they do that. Then the last thing you'll do is meet with your recruiter who will discuss salary, benefits, logistics, etc.
