Butler Machinery Management interview questions

Received a call back after submitting my resume and scheduled a time for an interview and was told I would receive a confirmation email. I waited a few days with no email about the interview, so I called HR to request it. Went to the interview and was grilled with about 40 questions from four different people. I was told that I would receive a call back the following week whether there would be a second interview or not, either way, I was going to be informed. I waited until Friday the following week with no news. I called the HR department and left a voicemail with the person responsible for that position. Not 30 minutes later, I had received an EMAIL stating the position had been cancelled and Butler was not hiring for that position anymore! Complete disrespect!! If that is how they treat their employees, maybe it's a good thing it happened this way.
