How close to your start date did they give you the final details like start time, location for first day etc?
Had my medical end of last week and was told on the day that all within limits etc so just figuring out when I should hand my notice in at my current place as all the giant stuff has been completed their end now aswell.
You probably have a bit of time to sit on it, if (assuming) you have a typical 4 week notice period.
I've heard from someone who works on the inside (Head Office) that:
They are currently looking to fill the April course, May course, and there's a course towards the end of the year.
And that courses tend to start around the same time of the month (i.e. 2nd or 3rd week of the month).
Also, they currently want to take their driver count from approx. 460 to 510- which is the purpose of this recruitment drive/campaign and this is due to plans for expansion from 22tph to 26tph and eventually 28tph.
Assuming you would be on the April course at the earliest, you still have a decent chunk of time to meet your notice period. Unless your notice period is a lengthy one which would make things a little tricky...(though I'd assume they would've asked you what your notice period was at interview and would be aware)
