Woohoo! So I can apply for other places and I just have to get past the first application sifting and driver manager?
Yes I believe it last for two years but I'm sure that I will be corrected if I am mistaken. If you apply for another position the application should ask you if you have previously attended an assessment centre and what the result was. You would still have to get through paper sift and DM interview as well obviously. But you have achieved what many don't!
