7 yrs bond is a lot for a Course on the Do228.
Ideal would be 3yrs,as the company needs to ensure you don't quit after they have trained you.
Important is also the reducing bond criteria.....preffered on reducing monthly basis.
Negotiate the salary well,especially Net salary,Not gross.
Perks/Benefits etc too in print in the offer letter.
Current scene out here is bad,so if you have an opportunity to get an approved training, go for it.
Endorsement on the licence is important don't end up with an approval only.
