Cheers for all the help everyone.
Had it today and I feel it went pretty well for what was my first ever interview. They kept on focussing on my weaknesses within the job description but Im hoping I did enough/persuaded them enough that I would be a good choice for the job.
I also smashed (I think) the little competencey test they gave me within half the timelimit, although I did forgot how many days there are in August/September which screwed me over on one question about billing.
Only problem is they were interviewing around 150 I think he said with only 10 positions available. Oh well, Ive done what I could and will hear about it next week.
Cheers.
