Been there a couple of years ago for a selection. First theoretical test which was pretty hard then the interview. Ive never met such a arrogants
pr@cks before, even on other interviews. Luckily i failed the test because i did not want to work for those ....... It is only that particular company i m not going to apply ever again even if im on the dole.
If you go there, im not sure if you get an belgian contract or if u can join as contractor. Taxes in belgium are really high.
Good luck
