I'm so astonished!
There´s a huge difference from my point of view, on helping other guys with questions like, can I use a Mac Book? Do I need a joystick? Link doesn´t work, or those are the question you are going to get: They will ask you to calculate size of ... or you will get during the interview X question, as this will make a difference from a candidate to another, perhaps to make to the interview if the scores are higher and there´s a limited amount of places.
But this is just my opinion, and also this was said in the last year interviews as far as I´m concern, to not share questions outside, as this might be a reason to be disqualified right away if caught, and that this was a competitions. Note that the fact you are now competing doesn´t mean you can´t work as team player when required.
