Flowserve interview questions

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.
