Michael Allen Company Associate interview questions

In one day, you need to interview with 5-6 different people. Most of then are partners of the company. They guaranteed to back to me with two weeks but I never heard back from anyone... During the interview process, some of interviewers acted like you won't get accepted at all. Both sides were wasting money. I don't like this process. Someone who enjoy meaningless pressure may actually enjoy it. After all, at least they should show some respect there and contact me regarding my result.
