Many thanks for the tips you guys have given so far, so is STAR or the CAR technique better(will look at both). @ cm1179 you may be right on the high staff turnover, if it is I don't really mind whether its working a few weeks or even just a month. It will look better on my CV for employment in the near future. it gives me a good idea.
Any tips on questions, do any of u guys know practically in estimation how many questions they might ask?
Thx again
edit: currently writing some questions down on paper and my own answers, gonna have practice tomorrow with my sister(she has been successful in both of her interviews which wasn't long ago, So I will see what tips she has that could help me)
