Gaylord Industries interview questions

After 1 month i received a conditional job offer. The conditions were to pass a drug test, background check, and references. Background check not complete on start date. Every other day about they kept saying I would start "tomorrow." I was called on Wednesday of what was supposed to be my first week and told everything was complete and I should start Monday. Then, I purchased a new TV and couch for my newly rented apartment since I relocated for this job. They ask for references on week 1 of the 6 week in the process. They never call them until after the 3rd party background check provider contacts you for your direct supervisor's contact information for every job on your resume. 2 of 4 of my references didn't call them back because one was on vacation and the other told me they left a message for HR and never received a return call back. I was told this was a factor to rescind my offer. No other definitive reason given for rescinding offer. I had a DUI from 10 years ago and I do not have bad credit. Although it's sad I lost the job, I think overall I dodged a bullet. I prayed every day, and they put me through horrible stress and lost lots of money to pursue this job. If the onboarding is this bad, I couldn't imagine how they treat their employees.
