My subject area is microbiology. There were some general questions such as:
What did you learn from your research.
What were the main limitations of your research.
What would you have done differently if you started again?
I was mainly asked questions specifically on my research.
It was not that bad, its just that my nerves got the better of me and coming away from it, I felt I could have answered some of the questions a little better.
I am off to get a very large drink now.
