Thank you all, your posts are helping it all come back to me and getting me in the right headspace. THanks for the questions to practise on too.

I had an interview just before Christmas and was pooing my pants (REALLY wanted the job and hadn't interviewed for about 4 years!). I was expecting more technical questions specifically related to the role (also health care) but got a lot of questions about how I interact with staff etc.
I have interviewed at this place before, and similarly the questions were more person based than technical based. I have my CV and the Position desciption printed out and going through it now, picking out examples i can use.
