n394,
Let's clear this first. How bad do you want to be an LAME?
So, does it really matter if you gonna have 10 years bond with MAS? Look at it positively that for 10 years you have a steady job!
METC is an ATO. One of the first the produce trainee engineers under the new DCAM PART 66, isn't that good?
Many many students lacks self confidence probably the way they are being brought up.. In order to face exams you need coaching, past years questions, tuitions et al... ..
During my time there were none and yet we succeeded.
'Right attitude' can't be trained or learned. It came from you. How you perceived things around you.
Honestly engineers are not trained, they are born! If you have a knack fixing things around the house, love to get your hands dirty or 'destroy' things because you need to see and know what make something work, then you have a bright future in any discipline of engineering.
In aviation maintenance you have to be multiskilled (all trades, mechanical and avionics) and multi-talent.
It is honestly not an easy course to pass. I am not discouraging you but it is a lot easier to take MBAs or degrees than the license!
Always be prepared for any interviews. Read up the company's history.. Who's the boss? What types of aircraft they operates? The different types of Boeings and Airbuses...
The A380, the whole world knows about it. Do you know anything about it? What about Boeing's Dreamliner?
Find out what the job is all about! Who is DCA? What do they do?
Read and understand the DCAM Part-66 syllabus.
What are Part 145 and Part 147 organization?
These will be asked to see if you have enough passion to give the edge that you have 'it' to make it through..
Enough spoon feeding already.

The ball is in your court, you decide what you're gonna do with it.
All the best!
