What to do when meeting your expected professor even before the interview?
Just for reference to others who might have the same question. The meeting was amazing, we communicated at Dinner, I asked many questions as well as she did the same to me.

In the end, I got questions if I am really interested to join her group..and my answer was yes since I saw she is ambitious, relaxed, open-minded, and collaborative. At the same time, I got semi-confirmation that she will do her best to make me the first option among candidates.

Therefore, my answers would be:


This type of meetings can really push the candidate acceptance and support forward.
following up Roland recommendation, be yourself and relaxed.
Ask your questions, try to see if your future supervisor is collaborative and motivating.
