Hi Andy
If they are offering you a TE3 (Technical Grade 3) position then basic monthly salary should be around 14000 dhs + accomodation or allowance of just under 10000 + some other allowances ie. transport + medical insurance and school fees for up to 3 kids. You pay 10% contribution to the latter two. Plus yearly Profit Share (So far!) Psychometric test is nothing to be worried about. Just answer honestly and with consistency.
I deal with the ETSS guys every day and I know that they have a big work load to deal with and could do with more good guys, especially if you have a good knowledge of composite repairs!
Maybe you should move this thread to Engineers thread. Wouldn't want to upset Nigel and his mates
(Only joking!).
