Stay away fro HERO. Egnatia is always looking for FIs, pays a good salary (around 2000 euros) and has the best reputation in Greece . Global aviation also opens FI positions from time to time with the same salary.
Good luck

Don't go to Hero Aviation! I hear only one student has come out of that school with the relevant licenses. It's a scam...

The website this morning claims they have 30 active students. A Facebook picture on 28 February showed 20 people who I assume were current students. So trade would appear to have picked up.

If you assume an even spread of joining dates throughout the training period then 15 equivalent students will need 150 hours flying plus simulator.
I shall let you work out how many hours flying etc is needed to complete the course, and from their website the resources in terms of aircraft and instructors.

And that assumes a static state without new joining customers.

With the current economic situation ~ a default on the IMF repayment last night, the Facebook reassurance about personnel guarantees from the accountable manager is to say the least courageous. :{
