Pros
I joined shortly after completing my university studies and I have learned so much in the time since I have been with the company. The company believes in its employees and encourages us to grow and do the best we can. This culture has given me opportunities (project management, presenting at conferences) to learn and grow that I know I would not get in other companies.
Nordeus is full of fantastic colleagues who are willing to pass on their experience and help each other out!
Other less important pluses are flexi-hours, great healthcare package, team events, and very comfortable offices.
Cons
None that I can think of.
