RH Trainer/Supervisor interview questions

Great instructions on getting to building and what to do when entered. However the large door with the company's name over head with the large numbered address was locked. Called contact and left message, asked folks walking by outside. No one was able to tell me how to get in. Saw a small unmarked door down side of building, it entered into a warehouse. called contact again, no answer. Finally called me back and advised "I guess I should have told you about that". Go through the warehouse. Security was set up like airport security (this was the 2nd red flag), tables, bins, metal detectors. WOW, what happened here?. Site tour was less than 2 minutes, appeared mainly to get me to interview room (3rd flag). Beautiful office, however saw no representation of public recognition on walls. No introductions to any staff members (4th red flag). Was advised on phone screen to prepare presentation and bring either laptop or flash drive. When arrived with laptop was advised that wouldn't work due to secure network. The HR person appeared to be all process and no attempt was made to put me (the applicant) at ease. Panel interview, one was a no show (more reg flags). I had applied for 2 different positions and the director advised me I was incorrect, then he got clarification from the regional training director who was on the phone. Asked about attrition, most recent class had a 50% attrition.
