I cannot emphasise enough the importance of doing your research. I had an interview at Newcastle University and I actually looked up the interview panel in the run up to the interview to ensure I had intelligent things to say to them that piqued their interest or was in their area of expertise. It worked – I got the place! The same thing applies to job interviews.
If you are able to fire their buzzwords back at them, they will be seriously impressed too.
And finally, most companies will ask for two forms of ID, including a passport or driving license, and proof of address no older than three months old. And if you get an interview, TAKE IT WITH YOU! A friend of mine forgot one thing in an interview with Asda, and they wouldn't even let her sign in, so she didn't even get interviewed. A hard lesson learned.
