Where in Haeco will you be employed for Line-BM- Tech 3 or Freighters.All this depends on your license cover.
Are employed thru an agency or direct with Haeco,this makes a big difference with your perks.Read your contract carefully and get it all on black and white.There is a lot of contracts to be had in Haeco.You might find yourself working next to a engineer with half your license cover but he is earning double what you earn,that hurts.
The bunch of engineers there is all good,just management is suspect.
Same as anywhere in the world.Good luck.
