International exposure and a relaxed environment.

People continuously late at meeting/talks.
The center is advertised as a multicultural center with people from over 50 different countries, but at BSC English is used as the last resource. It's common to have meetings or daily conversations in a language that not all participants understand enough; making integration for new people very difficult. This is not only my own experience as I've heard many people complaining about it. If you want to research at an international level, please, switch to English. The same is valid for emails.
Depending on which department your group belongs, there might be no or rare opportunities to network with other groups.
Low salary compared to industry.
