What is expected in a 5 minute postdoc interview presentation?
With only 5 min maximum, keep it to the point and interesting to them. They made clear what matters to them in their question


  How does your previous experience in vascular biology equip you to fulfil this post?


Find out about the post as much as you can and also the department (what do they specialize in). Find out what and who they want. Understand what your role will be, what their goals for this position are, in what direction to head. For example, research topics, but maybe also teaching duties etc.

Then use the presentation to show them why you are the perfect candidate for the post. Tailor it to their needs, no unnecessary information (you only have 5 min). This really depends on the requirements, but could be experience with relevant methods, openness to learn and use new methods / technologies (examples?), tutoring students etc. All the relevant experience for this post.
