Pros
My experience at Global taught me innumerable life lessons. I feel that I can withstand any level of management incompetence in any organization, and I am numb to a lack of recognition for my work. Since I went back to academia afterwards, this experience really is serving me quite well. Leaving GF Malta remains one of the greatest memories of my entire life, and the glow still hasn't worn off. I did network quite a bit there, and still have a stack of about 200 business cards. So, if my new venture fails, I feel like it should be relatively easy to get back into slinging wafers.
Cons
It was difficult for me transition back into intellectual work after leaving the company, since my "Engineering" position there was glorified babysitting. Global also made me unreasonably cynical about any type of corporate entity.
