Seconded National Expert

Seconded National Experts (abbr. SNE) are like the Erasmus students of the institutions: they already work in the administration of a member state and are lent to the European Union for a short period of time (from a few months to a couple of years). So they have to move to Brussels, usually with their families (a certain level of seniority is required to become SNE), and survive the shock of the first months.

Maybe languages are not their strength but they have a lot of experience in other fields. In general, they are quite relaxed as they know they are just passing by and taking a break from their routine.
