I applied online. The process took 1 day. I interviewed at Cornell University (Castleton-on-Hudson, NY) in Jan 2021
Interview
Very enjoyable and delightful. They didn't ask too many hard questions and personally, I think they value your passion very much. Should let them know that you are very willing to help students.
Interview questions [1]
Question 1
Do you feel comfortable receiving emails from students at your free time?
Got the required grade threshold for the position since you have to have taken the class or a similar course prior to applying. After I applied, I spoke with the professor and lead TA about the positions, then got a verbal confirmation they would be hiring me.

Question 1
How would you break down the device design phase for a Class III medical device?
No interview. Since I got an A in the class so I am eligible to apply. I wrote an email to the professor and got the offer. The process is very smooth.
