For what it's worth, here is a view from the recieving end of many CVs.
I only employ instructors, yet I still get CVs from people asking for charter work. Often same CVs are addressed to "Dear Sir" again an indication that the "I am very keen to work for your company" really means "This is mass produced and I have no idea who you are or what you do". So I don't feel guilty about not replying to those!
Another thing that really bugs me is complete unknowns who come in without an appointment DEMANDING to see me! These people have no regard for the fact that the time they have come in is actually allocated to someone who has had the manners to make an appointment, or to comlete work by a deadline, so why should I make time for a stranger with bad manners? Remember a CP is a busy person, and the reason we have front desk staff guarding us is because otherwise we would never get any work done.
In the early days I emplyed a couple of unknowns on the strength of their CVs. This was a mistake that I learned from very quickly. Mainly because the time and money spent training these peope to do the job properly made it uneconomical. Similarly the place where peope have trained is vital, and there are now only a couple of places I would recruit from. So, it really does matter where you do the training, and I tell you what, it ain't the sausage factories!
Now, if I have a vacancy I will scan the network and see who is out there, ask my preferred instructor trainier if they have any new graduates, or interview someone who is strongly recommended by a trusted colleague. If someone who had a good reputation and had already made a good impression only had a CV handwritten on the back of an old envelope that would be fine.
SO: Make a good impression from day one of your training, get to know people, listen to people, never get drunk and make an idiot of yourself in front of other pilots, and remember, you make your own luck in this game.
Good luck!
