Pros
A paycheck. That's really about the only perk. I would say the 9/80 work schedule is nice, but it's not guaranteed, and they work you like a dog the "80" hours (more like over 100) that its worthless. And the projects you work on are cool. And there's a lot of room for growth if you stay.
Cons
This place is essentially a sweatshop for really intelligent people. And they all drink the kool-aid and consider this place THE BEST place to work. I don't understand it and I never will. I'm a hard worker, but what's the point of working if you working crazy hours. Most of the people on my team barely ever get to see their families. Hard pass. Especially working in the Contracts group, you will be expected to work weekends, 10+ hour days, and that vacation you scheduled? Welp, if a project comes up that you need to work on, you might have to cancel. There is high stress, and NO work-life balance. Not worth it. Super expensive insurance, 2 weeks vacation off the bat (the worst I've ever had). I can't stress how much I hated working here. It's certainly for those people who thrive on having work be their entire life. That's not me. I work hard to play hard. This employment was not for me. Also I just didn't like the people. Everyone is so cut-throat, they're willing to do whatever for that next promotion. Very little comradarie that helps make the work day better. No free coffee, just an expensive cafeteria with Green Mountain coffee. Blech. Also - The ACRONYMS! Oh my god, it's like learning a new language before you get to learn how to do your job. It makes it so much more difficult.
