I approached them at my school's career fair and was schedule for an in person interview the following day. That interview was about 30 minutes and had most of the general interview questions.
I then moved on to the next round which was another one on one interview with the sales hiring manager. That was about an hour which had a lot of the similar questions and then more information about the position and the company.
The final round had me go up to the office in Milwaukee where they put me up in a hotel since I was traveling from my school. They also reimbursed for gas. The final interview started with a tour of the office and a mini history lesson on Milwaukee. Then there were three one on one interviews roughly 45 minutes each. They asked about three questions each and then answered any you had about the position or the company.Overall everyone was very friendly and helpful.
Something to remember for these interviews is that they are only asking three questions each meaning that you need strong answers because there are not a lot of questions to redeem yourself on. Use the STAR method (Situation/Scenario, Task (Goal you were working towards), Action (Tell what YOU did; make sure to use "I" and not "we"), and Result (Make sure you have a positive outcome).
Many of the questions were somewhat similar and it is tempting to use the same stories with different interviewers, but they meet afterwards to discuss and using different stories tells more about you.
