After much wailing and gnashing of teeth I have an interview in Vaud,CH.

Its a tech position and its a second interview following a ph tech test.

Apparently its a panel of an HR bod and Line Manager.

Would anybody be able to shed any light on the differences between UK and CH interviews if any?

They are paying for all my travel costs, is this significant or de rigeur?

I am sure I will do a bit better than Spud from "Trainspotting" but was wondering if their where any faux pas that I would not be aware of coming from London?
