IBM

It's a good place to work with talented people.

One of the best places to work in GDL.

Additionally, the lab gives you a lot of flexibility and freedom; you just need to deliver as an employee.

The offices are really far, and the commute is awful. There's not much to see near the office.

Growth within the company is sometimes hard, since not all managers care about merit. They place a lot of value on perceived leadership (not always real leadership), which makes people leave for better opportunities outside.

See the cons part. They really need to value their employees. All of them, not just the ones who talk the most. Everybody knows those are almost always the ones who know the least.
