Nokia

Some of my colleagues were really good.

Bad management; they do not understand technical decisions they make.

Bad tech; no one in all the teams I worked really understood the technology we used, thus it is hard to grow in such an environment.

Severe underpay.

Laidback culture.

Feels like the company is living on old, meaningful things it did before, and nothing good and new is coming.

Lots of bureaucracy.

Hard to be promoted, even if you are a high performer.

Very small team budgets.

Incompetent decision-makers on all levels of management, including R&D.

If you want to build world-class competitive tech, pay decently and hire professionals who like their job. Obviously, you can't find them on the lower end of the market.

Get rid of bureaucracy and promote capable people faster. It now seems like most of them are leaving the company after a while.

Stop wasting money on things the company doesn't really need and focus on technology that brings money. Maybe then you don't have to fire staff three times per year.
