MTR,
welcome.
I suggest you read this discussion:
http://www.pprune.org/middle-east/24...need-know.html
There are about 50 pages to read so it could take a while but there is a wealth of info and opininons to be found. as the discussion dates from 2003 you will be able to get an idea how things have changed over the years.
For your information, there is a pool of 320 captains of about 12 guys who interviewed last year and I dont think there is any plan to empty the pool soon. I might be wrong.
There is also a pool of 320 FO's who is being emptied as we speak.
I have a few friends working at EY and they all like it very much. but of course you ll read here about some people who dislike it.
good luck
