I think this will be my last post in this thread as it's turned absolutely toxic with the negative comments and now evidently we have scaremongering as well.
Group assessors will know what they are looking for and will have done it before, there isn't one person trying to keep track of what everyone is saying you'll have multiple assessors looking at individuals as the day progresses and all the information is collated at the end of the day.
Of course recruitment will be aware of this thread, social media and online forums hardly take the likes of GCHQ to monitor but this scaremongering that everyone will be indentified by their posts and the fact that they have admitted they have already passed testing is ridiculous (unless your username compromises you're real name of course...)
At the end of the day, this is your journey to becoming a train driver, regardless of wether your doing it for the money or it's a life long dream, your decisions and actions are yours alone, don't let others views affect them. For those that have got this far, just be yourself on the day, ask the questions you want to ask and wait for the outcome.
Best of luck to all.
