Can't but agree with Mamaput, as I am myself one of the ex HAI CFIs that are now working in Nigeria...for Pan African.
I have HAI to thank for every single job I've had the last 11 years.
Not only for the image the school has across the world (Job #1) but also for the all important network you build by working there...(all the other jobs)
Chances are that in every company you can think of applying for a job with, someone from HAI / BA either works there or knows someone working there.
Easy to get a reference for sure. Got my other jobs through former room mates, students and of course Patrick Corr himself.
I can honestly say I wouldn't have had my career progression if it wasn't for HAI. That being said, there is no guarantee of anything...you have to work hard, be professional...and be lucky. Don't underestimate luck. A lot of very good pilots from my time at HAI are no longer working as pilots...
