Pros
Work in a super atmosphere, trust in the employee, independent satnows. If you are an organized person and can manage your own working time, in a proper way, this is the perfect job for you. Full confidence, in knowing what you are doing and being a specialist in your field.
Cons
Here people work for many years each, also the team is old and knows each other well. For some, this may be a downside. If there are no problems with networking, it is unlikely to be too much of a downside.
