Transdev Autonomous Vehicle Operator interview questions

They called me, had me answer some questions about traffic, and I received some pre-employment paperwork shortly after. Upon filling out the package I received no further communication (It's been a bit over a month since the tentative start date on the papers). When I contacted the interviewer again, he said he didn't know where my application was and to ask HR. HR has similarly not responded to my inquiry yet (sent by email because they don't give a phone number for HR.) Don't even bother interviewing, they'll waste your time.
