Pros
Vienna is a very nice city if you speak good German. Good canteen.
Cons
Very low effort / low engagement staff. Lazy atmosphere. Arrogant. Incompetent. If you are a professional with a work ethic you will be quickly be demoralised. I had to leave as I felt shame taking money from the taxpayers of poor countries and giving nothing back. Most people don't give a damn. Me, Me, Me. Nobody will care if you have an idea to improve the place. So many amateurs but the drunken monkeys of HR would have to be the worse. Basic decisions and processes that take hours or days in commercial enterprises take 6 months, 12 months, or are kicked down the road indefinitely. Always, always blame someone else. Never stand up and be accountable. The entire organisation needs a cultural re-think. Hire high level performers from commercial entities where there is a performance-culture.
