Flowserve Mechanical Engineer interview questions

I talked with them at my school's career fair. They sent me an email that night to come in for an on campus interview. Then a few months later they invited me to an assesment center in Long Beach, CA. The assesment center was three days long. The first day was just for traveling where they fly you out to a nice hotel and provided a $35 dinner voucher. The second day had three 30 miniute interviews, a case study and a team building activity. The last day was a quick tour of their facility and then flying back to school.

They flew us to North Carolina for the interview. First day consisted of a group activity in which they sat us in a room surrounded by observers and put us in an imaginary budget meeting. Then we had to prepare a case study in about an hour from endless amounts of information to be presented the next day. We ate dinner and talked about benefits. Day two we had two 1 on 1 interviews which were fairly simple and standard and we also gave a 15 minute presentation over the case study that we had prepared the day before. They said they were going to get back to us in a week with offers. Didn't hear for about a month, only to be rejected.
