Colo18 advice
Hello colo
I assume you had been acquainted with the already available preparation sources online (thoroughly - you have no excuse )
Now you must be under tremendous stress but this can play to you advantage
Even if money is tight see to it that u have a catchy dark suit ( it says although I am unemployed but I have standards and self confidence and not here to get wide body hours and wave the flag )
The process is honest and straight forward as you are evaluated on your over all performance and compatibility
Be honest when you answer the psycho questions and during the interview with the psychologist - they can detect lies = no job
Make friends during your stay at the hotel with the other candidates .. Your group exercises will be greatly improved when you guys know and respect each other
Good luck
