Re: I have an interview with LRQA next week
To add to Sidney's points, I would mention flexibility. The more options you can provide such as a range of codes you can cover, the more valuable you will be to them.
I suggest summarising your existing experience in such a way that you can easily show the areas you can cover and take it with you on paper, laptop, memory stick, or whatever is easiest.
I guess they will be looking for people who can provide solutions to their problems, so present yourself in such a way as to make it easy for them to see what solutions you can bring.
