Honestly, I was a little overwhelmed. I won't disclose the main point's for my own possible job security. It was very in depth, like I said before they don't want just anybody. The interview will make you realize the kind of job you signed up for and how serious the MTA actually is, more than one would expect even for a cleaner. Like I said, they want the best of the best it seems and certain correct response's. Put it this way it's not your average factory, trades, union, or tech firm interview. It was the most professional interview I have ever sat in. On a side note having any of those other one's listed in your past for an interview will help as they asked a few similar questions. They also send you an interview preparation attachment with the interview confirmation e-mail, which definitely helps but still is a challenge when you finally get there. I'm not saying this to intimidate anybody, but it's just my opinion based on my own experience. Good luck again.
