I had the pleasure of working at CERN (European Organization for Nuclear Research) for over 4 years.

It is one of the coolest and most diverse working environments I’ve ever seen, with plenty of young people and outside work activities. Sitting on top of the border between France and east Switzerland, you’ll find its two large sites where a few thousands of people work every day.
