I applied online. I interviewed at UC Merced (Merced, CA) in June 2017
Interview
There was none really... unfortunately you are chosen based on past courses you took. However if I felt uncomfortable I could tell them. You applied online and then anything else was accomplished through email. I don't think they have the manpower or resources to speak with each person.
Interview questions [1]
Question 1
How comfortable do you feel teaching this course ?
