Mine was also on the 6th. I thought the interview went well and was expecting a job offer after passing the medical, so the email I received today came as a surprise.
At the interview, they said there were 3 candidates left including myself to interview that day, and there were 2 spaces left on the course out of 12, so maybe something changed.
Gateway is expanding though, and if they can fit more services in, they will need more drivers. We've done the psychometric and interviews which is the hard part, so it's just a waiting game now.
