Initially reached out to by a recruiter for PM. Took online exam and was called back within 2 days for phone interview. Another week later and received call from recruiting coordinator asking me to fly out to HQ in Wisconsin to interview for TSE and PM. They pay for everything, including food and transportation. It was snowing and cold that day, so we weren't able to do the full tour, but they still took us around the buildings using the underground tunnels. Campus is like a giant adult playground, and you will have a "guide" with you at all times, so basically the entire day you're being watched. Overall, was a pleasant experience and everyone seemed nice. Was given offer 2 weeks later.
