Shaun simple be yourself, dont act up just be you as you are obviously keen and you definatley care to get the job, that will shine through.
Enthusiasm always does, answer all questions naturally and never in a word, always go for the longer (but not boring) answer, with a smile and keen to go look.
Be extra confidant, almost answer a question as if you are working there, but not in a cocky way, just speak as though you have given every question they ask prior thought, that will show you do care and want the job.
As big sister suggests try to think out questions both of which you might expect them to ask, (her examples are very good) and questions you might want to ask them too.
Above all Shaun, be on time, look smart and be lucky... you have made a great start already sweet heart by caring enough for this job to post your thoughts here on tibb.
I know you will do well my friend
