i think most specialised scheme are designed to be hard, otherwise why would they pay like near 5k for FCH. Other civil service MX FCH only gets around 3.8-4.4k (in forum's range).

I think Foreign Service has an assessment centre consisting from 4-5 rounds from English test to presentation skills to Translation skills, and stress test designed for working like FO.

Haha, they are tough and the job is tough too. So kudos to them!
