I've been through the assessment day now so figured I'd post some information here incase it helps anyone out looking for the 'new process'
This was for a Man Vic position but guess its the same process everywhere now
So there was 30 of us booked on the day. A few didn't turn up (?!)
There was tasks,
Observation task - watch a 30 min video and mark down what the assessors ask for throughout
Group problem solving - This was like a mental puzzle, split into groups of around 5 and as a group you have to figure the answer - you've got 20 mins. As far as I know, none of the groups on the day got the answer right. But it wasn't about that, it was about how you work as a group, do you contribute? Do you work well with your team? Are you letting people speak? Are you speaking yourself? Probably all sorts of things they are looking for to score highly.
Multi tasking observation - Had to build Lego under precise instruction whilst watching a video and answering questions on the video. This comes pretty quick, was pretty hard work - probably seeing how you handle the pressure situation rather than getting everything 100%
Communication - This was fairly straight forward, listen to some train related comes, what was good what was bad - write it down and explain why
After the tasks, the managers go away to discuss individuals and decide who warrants an interview.
Our group got whittled down quite a lot, more than we expected - from almost 30, 6 went through for interviews. I don't know if this is normal or our assessment day just had a lot of not what it takes people, just seemed like a lot went home before interviews.
The unsuccessful applicants got sent home and the 6 that were left had a break for lunch
After lunch was the interviews, these were really short -
2 situation based questions - The situation is X, can you explain how you would handle this and why
2 competency based questions - Tell me a time when X
Then the standard, tell me about yourself, what do you know about northern, why do you want to work for us, why do you want to be a driver that sort of stuff
The actual interviews were really short for us all, I think with the amount they culled the field before hand, they kind of already knew who they wanted and maybe the interviews were just to confirm or highlight any red flags.
Anyway - Just thought I'd type this up as right now there's not a right lot of information out there for this new style assessment day and interview, hopefully it helps someone going through the same thing and gives a little more idea of what to expect on the day.
Good luck
