Cymer Production Engineer interview questions

Phone call from recruiter, followed by phone call from hiring manager, which was followed by onsite interview. They did not follow up at all after the interview, not even a system generated message saying they have hired some one else and the req. is now closed. It has been 5 weeks since the interview. I was flown in early morning on a Friday and flown back the same day. My reimbursement request for rental car is still in progress, I have submitted the supporting documentation for the 3rd time now. I am not sure if I will ever receive the check. This has been the most uncourteous company I have interviewed with.
