Pros
I'm not being petty; I sincerely can't think of any. There were a few neat things about working at my specific site, but nothing good about SGS as a whole.
Cons
I've always been skeptical of big corporations, and this place turned out to be every disgusting stereotype I ever imagined a mega multinational corporation to be. Their corporate culture, at least in North America, is a ruthless snake pit of morally dubious individuals, while their actual corporate functioning is so bloated with bureaucracy and red tape that they are utterly incompetent to do anything. No one wants to take responsibility (read: blame) for any decisions, so no one will actually ever make any decisions or provide any answers. They just pass the buck around for weeks and months until you forget or lose your mind. EXCEPT when it comes to money. When that's involved they will strike fast and hard for that precious bottom line. SGS is by far the worst company I have ever worked for. They completely dehumanize the people who work there. It's strictly about the numbers. It doesn't matter whatever they've told you, promised you, or even stated in writing. They will go back on their promises, they treat their suppliers like garbage, and their employees as assets on a spreadsheet. I really can't say enough how much you should avoid working here. As for the numbers, we were all woefully underpaid, at least according to Glassdoor's own estimations. Insurance was okay-ish. I've experienced far worse, but also much better. Retirement benefits a little below average in my experience. Vacation time poor, but sick time mostly makes up for that. For a company that's constantly ramming "Integrity Training" down everyone's throat, there is a stunning lack of it among their corporate management.
