I love the questions I get in workshops. It’s nice to help people with answers. Sometimes questions surprise me with how they’re phrased or the details involved. Last week I had to pause to think about how to answer a simply stated query:
What impresses examiners?
You and your thesis. Reading a significant original contribution to knowledge; getting to discuss it with the researcher who did the work.
You are impressive: the work, the talent, the commitment.
