Obviously I want to seem as interested and eager as possible
not only seem, but be interested. Genuine interest will 100% shine through every move. Your questions, conversations, attitude and such.
I would definitely have at least 10 questions ready before coming to the school. Most might be answered during the day and some may emerge.
Nobody here will be able to put questions in your mouth; they have to be unique to you and what is important to you.
On one of my interview days, there were 5 of us and we interviewed in turns. Some went out in like 10 minutes and they had no questions to ask and some stayed for around 25-30 and had questions to ask.
Having questions to ask makes conversations flow better and shows mutual interest.
#1 job interview mistake is when people have no questions to ask. This is rude and shows lack of interest. I have interviewed others for employment and know how it works.
Some topics for questions:
1. Research
2. Curriculum
3. Ability to join academics after graduation
4. Combined degrees
5. Clubs
6. Rotations
7. Process to locate rotations and residency placements
8. Student resources
9. Other volunteering and involvement opportunities.
Most can be generally answered throughout your interview day, but you can always come up with more specific questions.
