Surely sleep is a good idea??
I am surprised the managers int is first in your case as usually it is the other way round.
Fault finding test: Is this simply various shaded dials where you work out the answers from a key? Do you also have to work out which switches work from sequences of switches? The latter is harder as you have to imagine in your head the changing sequences
Be careful with the fault finding test - it's not as easy as it first looks. I.e, from memory, whilst the practice paper has you thinking it varies on the shade of colour in the dial - it dosent. It works on the basis of the where the needle position is, and what sector / zone its in, and i think you start from the lowest first (I'll try and check this after Coppers on more 4 or in the morning!)
I have to admit also that im surprised you've already had the interview - the way the TOC that i did mine with, works on the basis of:
You apply,
If you get shortlisted, then you'll be sent the details of the assessment day / details,
If you decide to agree, then you'll get sent practice materials to work through,
Assement day involves Concentration Test, Group Bourdon and the Trainability test - TOC i did this with had a listen to the passage section and answer questions from memory, which was about the application of Glop / American version of Sandite, the reactions test, then the structured interview. But, fail any section as you go along and your out of the process.
I'm writing a basic app to simulate the reactions test so I can practice it (Not got boppit) - Do the colours that appear on the screen always appear in the same place or move about?
I would say that it probably depends on the system being used - Where i had my assessment, they were still using Windows 95 computers - so it might be different on another system. However, the coloured dots did move / change position around the screen.
Anyone thinking of applying should just think of the shifts. If its Depot Driving then its going to be nights including 0600 to 0700 finishes. Or 12 hour nights, starting at 1900 and finishing at 0700. If its mainline passenger theres probably going to be early starts. Even worse than the traditional 0600-1400 earlys. I've seen stuff like 0400-1300 and 0500-1530 on diagram papers I've seen left on trains arriving on depot. If its freight then expect even worse, shifts starting at times like 23:00, 01:00, 03:00! Thats what it was when I looked into DRS.
One of the depot jobs i had looked into had shifts starting at anything from 18:00 to 03:00 am, and 19:00/20:00 through to 06/07 am with 3 days on nights, and the 4th during the day. Fortunately, knowing various people at the depot helped me to carry out research about the job which may have helped further down the application process.
Hope this is of any use.
