ETS Clerical interview questions

I drove 45 minutes just to find out they rescheduled open house. I received no such notice via email or phone only a note on the door when I got there. I came back again a second time, and they said they couldn't find my application (which took almost an hour to fill out) and that the person who referred me doesn't even work at the specific site. They had no communication at all with the recruiter who reached out to me. I sat waiting for more then 3 hours just to be told that they aren't hiring anyone else. The manager was rude and sarcastic and told me to come back next week, so I picked up my stuff and left.
