Pros
work/life balance is good. that is why this is a great company for those who have families and kids. once in a while you are asked to stay late, but usually no one checks your hours. in addition, lunch is available in a dining room which saves time to go to restaurants. gym is also available, very cheap.
Cons
this is a company that states with arrogance they earn more than a billion dollars a year. but what about your employees? what about the salaries? what about events for employees (fun days, parties etc)? Technology: this company does not pay a dime for 3rd party software that is not free/open source. Being a tech-leader-company or being innovative does not interest anyone in management.. As the company does not spend money on open events, or on sending employees to events, the brand "nice systems" is not familiar, so it is very hard to hire new *talented* employees. As salaries are low, and there are no raises, the talented employees leave, so the company is stuck with juniors or with those who do not believe in themselves enough to leave.
