Cornell University

First, I would email the professor that you are interviewing with and ask what types of projects they are currently working on and what laboratory techniques and skills they utilize. Second, I would read the last 3 recent papers that came out of their lab. You need to come up with specific reason...

Come into lab. Check on my animals to make sure they are doing well and don't need any maintenance. Look at my experiment list and see what I need to do that week. Consult with the professor. Work on experiments. Go to lab meeting. ASK LOTS OF QUESTIONS.

Think about why you want to become a TA, what would benefit you, any statistics experience you’ve had (classes, internship, project team). The questions were not statistics questions, but rather about the teaching experience and how you would handle certain situations.

Grading homework, proctoring exams when needed, helping professor grade exams, answering Piazza questions, holding office hours, and answering emails from students. It is about 10 hours per week.
