If you work in academia, you don’t need to learn a new language. English is the working language. Also the 5 weeks of holiday is nice, but what really helps is the working day.
I started as a bioinformatician a month ago. I come in to the office at 0830 have coffee from 09:00 til 09:45 with my boss and colleagues, work a bit, have lunch from 12:00 untill 13:15, work a bit, go home at 15:30. That’s my day.
