I got my very first job interview in about 3 and half hours.
Strangely enough, while I'm not very nervous (I have a quite calm demeanour), I'm more nervous than I have ever been for my exams (Which I suppose isn't very hard). I suppose what aggravates my nervousness is the fact that my situation here in Lisbon (And particularly of my entire family overall) is very bad. This has forced me to try and get a part-time job I was already planning on, since last year.

From what I've heard, job interviews are tricky business, and having experience being interviewed really helps.
I was wondering what helpful tips can anyone give me so I won't do or say anything I'm not supposed to do.

In any case, the job interview is to work in my College's Student Council where we do college-related tasks (Photocopies, scanning, etc, etc.) the students need. I shall be working in the post-labour period, which would go from 5 PM to 8 PM.

Tips? Advice? Death threats? Marriage proposals?
