Mmmm ...
Sorath .... With 28 years experience I would expect you should have an A&P with IA and plenty of supervisory experience as well ... if that is so then I would suggest the money offered is way too low ...
If you have 28 yrs exp. and no tickets then your only a 'fitter' ....
Keep in mind that you also have to get a UAE AME license and for some folk that can take some time ... the company may not want to pay you top money till they know how really useful you are going to be .....
You should also be able to negotiate 6/6 if you want it ???
Good luck ...
