Great company with good peer support

CEO approval

Business outlook

Pros

Colleagues and supervisors are respectful on work-life balance! Due to the international focus of many of the c40 work, there are sometimes evening calls with external partners from different time zones, but supervisors are generally flexible and support time off in lieu.

Cons

People are so nice that you just feel bad to say no and then end up doing more work. It is a good con to have.
