Pros: Some good projects, nice people.

Cons: A lot of doom and gloom.

Pros: Best place to work. They have flexible working hours.

Cons: IBM is probably one of the best places to work. I can't think of any cons.

Pros: Good salary, interesting customers and work, and exceptional peers (for me, at least). It will depend where you are. IBM, particularly on the product side, is not one company but a collection of small companies. This is good; it allows that product the flexibility to operate as its own entity.

Cons: Highly unstable environment. Every few years, they will, without warning, just axe about 20%—seemingly just to keep everyone on their toes. This is usually sales and tech sales; lab services (where I was) are rarely touched. Massively bureaucratic. It needs to be; it's a lot of people, but if that's the kind of thing that bothers you, think twice. They make a big deal about there being amazing growth opportunities, but the reality is that if you are good at a job, you will stay there or get promoted into a management position, where you will stay. If you are not good, it's entirely possible to hide, which isn't great. Almost everyone knows someone who adds no value, shirks responsibility, and just collects a paycheck.
