Cystic Fibrosis liaison nurse interview

Hi I have an interview for the above post on coming Friday. Presentation topic is 'how personal governance relates to the band 6 CF liaison nurse role. Interview panel includes the lead liaison nurse ,modrn matron and the consultant. I know the interview is going to be challenging for me, I currently works in the CF unit as a band 5 nurse,never had such an interview. I have read most of the threads in the site, Any specialised advice will be greatly appreciated.
Thank you
