Band 6 interview presentation

[Spongebob]

Hello

I have just been offered my first ever band 6 interview on a healthcare of the elderly ward. They have asked me to do a short presentation on ‘how I will make a difference to: A) patient safety OR B) infection control?’ 
 

I am really stuck, how long would they expect the presentation to be? It is a 30 minute interview overall. Also I’m stuck on what I can talk about? Any tips and advice is appreciated

 

Thank you
