Pros
Challenging, interesting work, with plenty of job mobility. Everyone changes jobs internally every couple of years, and that's accepted. As a whole, my coworkers are smart, industrious, and collaborative. They are genuinely nice. Even the jerks are nice compared to some of the yo-yo's I've worked with in other companies. The hours are very manageable, and it's possible to work 40 hours and have time for a real life outside the office. FT employees appreciate the perks like a free gym, subsidized lunch, on-site Starbucks, and employee parties and family days.
Cons
There's a lot of fat here. The marketing organization in particular has a lot, and I wonder how they keep their jobs given how many airy ideas they have without results to show for it. I don't think most of them realize how good they have it here, since it's been so long since they've had layoffs, so they can be a bit complacent. Many people work remotely, which can be a good or bad thing, depending on your work style and perspective. It can be very bureaucratic. A simple task can be routed to five different people before you finally find the person who can get it done. Finally, it is a matrix organization, so sometimes you feel like you're herding cats.
