If electronic send the CV as a word document. I tried it as PDF a few times and there are still places without Acrobat!

My only advice would be to what others have said and swat up on the job, find out as much about it as you can, the whole business and their bigger picture and have some questions ready. Be enthusiastic and imply its this interview of which you future rests. Chances are its not, but an interviewer wants someone who is keen and not likely to go taveling for a year. Which brings me to another point, if you have travelled get it on the CV, and if it comes up in questions tell them about it but that is part of your life that has gone. At your age employers expect a traveler and won't hire if they suspect!
