I worked at Midwestern University full-time
Good professors, good education
Outrageous tuition and little support during fieldwork
I applied online. I interviewed at Midwestern University.
Set aside a whole day. I've never had a longer interview in my life. You will talk to HR, PIs in the department (some departments will split that part into multiple segments), and then you will also likely talk to current lab staff. It's a lot of the same questions over and over, but be prepared for several hours.
