For anyone else that is due the assessment I'll go through what the day panned out like:
First the Dot test. On paper, which was a relief as i found the computer version harder. I managed to get nearly halfway down each sheet before told to change. 5 sheets to complete.
Had a little break and next:
The train-ability for rules & procedures test. Had to listen and read a passage about a "GLOP" train. We had 5 mins to read and make notes and try to remember as much information as possible before the passage and notes are taken away. Then you answer 18(i think) questions. Didn't do too badly on that.
Then we had another break.
Then the people that failed either of those tasks were sent home. Out of 13 around 5 or 6 failed.
Next we had the dials test. Which wasn't too hard to be fair.
Followed by the Fault finding test. Which was a little bit more detailed, but as long as you listen and read the instructions, and stay calm, you should do okay.
Then lunch followed by the reaction test.
You sit in front of a screen and a console with 5 coloured buttons, a low and high pitch button for the sound pumped through your headphones and two foot pedals.
You have a little practice where colours appear on screen, low & high pitch sounds are sounded to the headphones and pedal squares appear on screen.
Just take your time on this. When it starts to go really fast, just compose yourself and carry on. You WILL make mistakes on this (i started pressing the pedals when the sound was going off!) but don't worry too much.
I must admit, despite the competition for the job. Everyone there helped each other along, we even stayed until the last person completed his reaction test! Its a shame everyone couldn't get a job. Good bunch of blokes.
