Pretty easy and straightforward. I had two interviews - one online and one in person. They are very friendly and ask reasonable questions. Expect questions that assess your technical ability.
I applied online. I interviewed at Mason Companies (Chippewa Falls, WI)
Interview
The interview process after my initial application was sent out included two video call interviews, one with the head of the department and one with the people who were to be my direct supervisors.
