IBM

Surrounded by smart and creative people, an empathic manager, a decent salary, very good benefits, flexibility in work schedule, and having IBM on a resume.

It's a huge company with lots of inertia. Any sense of job security does not last long. Any 'pro' listed above is totally dependent on the team you are on and who the director and VPs are higher up in the org chart. One person could have a great IBM experience, while it can be completely awful for another person. People are often more concerned with self-preservation than producing reliable, consistent products and experiences. There are tight budgets and reasonably high attrition, which often does not result in the role being backfilled.

Be honest, especially those in HR and those who control our benefits. Lower-tier IBMers are not idiots.

There is a serious issue with anxiety over job security, especially for those who are high-performing. Why, in the world, would you get rid of efficient, productive, high-performing engineers at a time when the company is stressing increased efficiency and productivity?
