Pros
Presitigious organisation, looks good on your CV as long as you don't stay too long. Sport-centric culture. Beautiful offices, lake-side setting.Opportunities for travel. You get to see the Olympic movement from the inside.
Cons
Very political internally. Poor management (President not involved in day-to-day, that's director-general's job) and lack of operational leadership. Much empire building. Poor project management. Many "initiatives" outside world doesn't care about. Ethically challenged. It's all about the TOPs (Olympic Partners), the TV contracts, the money, nothing else matters. Staff salaries are low vs the external market. Very little training or career development. Many staff are institutionalised, a lot of time servers at every level.
