I left GSS last year.
Now I keep bumping into many ex GSS guys in HK who feel, like me, that the management there are devious, untrustworthy....basically a lying bunch of bar stewards, watch out!
I think these days it would only suit low time, inexperienced folks who want the B744 rating and willing to put up with the forementioned stuff.
I for one thought we were duped by the management there and so do a lot of other good nice ex GSS people...pity.
