Pros: Flexible schedule, relaxed environment, and quiet.

Cons: The facility is very old school, not a lot of light or excitement. The company still uses old practices, i.e., still Waterfall and barely transitioning into Agile. A lot of the employees are typically older.

Pros: People are mostly great to work with. They are very reasonable and goal-oriented.

Cons: No way to negotiate salary or increases.

Pros: If you are not ambitious and not passionate about your work, if you don't expect much in terms of professional respect, opportunities, or fair compensation, and are fine with being laid off at any time, this might be a company worth considering.

Cons: IBM internal performance review rules promote meritocracy. You can work very hard, accomplish a great deal, and still be given a bad or average performance rating just because you were not visible enough to the right people or simply because it was your time to take one for the team. Most employees I know have given up on trying to improve anything in the products. People are in "survivor" mode – minimum effort for maximum benefit, and don't stick your neck out. A lot of truly talented technical people have either left on their own or were laid off. People that seem to be staying behind are poor souls that are stuck at IBM for some reason, or those who play internal politics well.
