First a phone interview and a basic skills assessment.
For the second round, it was a full-day affair in Wisconsin including several rounds of informational interviews, and a tour of the campus.
Then a combination written and spoken skills interview outlining approaches to basic scenarios with a project manager.
Then, there was a mock pitch of a topic of your choice in front of a small group (3-4). This was expected to be prepared in advance and delivered without presentation aids.
Finally, a wrap-up behavioral interview with an HR representative.
