K, so I actually had my first job 'interview' today. (yeah, I finally applied for some jobs
)
In short, it was hard and it sucked. I had to be there at 13.30 and was out by 16.45.
Now, I put 'interview' between quotation marks because it was really more of a preliminary language test than an interview. Basically I was given 2 situations (having to do with insurances) to which I had to respond with a letter. In both cases in English, French and German. 
Now...English was easy, but I don't know if you ever wrote or saw a French business letter...they read like 18th-century poems, I'm not kidding. You have to use all these formulaic sentences and be super-duper-polite. It's a complete bitch. The German letters were very sucky.
The worst thing of having to write in three languages (and thinking in a 4th) is that you will start confusing them, especially French and English have a lot of similar words. But I even 'invented' the German verb 'refusieren' (to refuse, refuser) 
Last part of the assignment was to write a text of about one page on a topic of choice, but doing 1/3 in every lingo. So I started in French, moved on to English and closed in German. It was a freaking massacre, haha...yeah, I've got a feeling they won't be asking me in for a second round. We'll see.
Sounds like a real bitch of an interview!
