Pros
Free coffee. There are also a few (very few) that are willing to help train you as long as you ask.....and keep asking.
Cons
Major lack of OJT, very cut throat, contractors are treated as indispensable, everyone in flight test has nothing but negative reviews of said place (including the permanent workers), the programs used for production are quite often inaccurate and tons of red tape has to be cut in order to correct such an anomaly (It can literally take days to install a simple bracket), too many people, not enough work (yes, I said that right) which means no training yet you're told to look busy. That means sweeping the floor or walking around the airplane for 10 hours straight. The G650 is supposedly behind on production so Gulfstreams knee-jerk reaction is to hire a large sum of employees as well as bring in outside talent from other Gulfstream plants (MA and FL). So, here we have 20 people on one aircraft fighting for something to do while the new contract employees get kicked around and swept under the rug. I had high expectations of this place. I had always heard good things....until I worked there and heard it from actual employees. Maybe they're admin sections is a stellar one but to be a Final Line Mech III in Flight Test is by far the worse example of training and management that I have seen to date. Also, if you ever get a chance, look inside one of the aircraft in flight test. Rivets, nuts, washers and safety wire can be found throughout the electrical compartments. Safe? I think not....
