I have been invited to interview for a postdoc position, and as part of the interview I've been asked to give a 30 min presentation of my relevant previous research.
This particular position would be a change in direction from my PhD in terms of skills and subject area. However, I have had some relevant experience from previous positions - which I explained in my cover letter for the application.
My question is, for this presentation what would be the best approach:
Talk at more of an overview level about bits and pieces of relevant work from various positions - most of which were years ago.
Pick one or two relevant research stories from my previous experience, and present more like a traditional research talk.
Highlight the relevant parts from my more recent research, i.e. my PhD.
