I applied through college or university. The process took 3 weeks. I interviewed at Pole/Zero (Cincinnati, OH) in Mar 2021
Interview
Talked to them at the career fair. Got an interview in person which consisted of a written test covering ~3000 course level circuit knowledge and a talk interview with two of the engineers.
Interview questions [1]
Question 1
The written test covered basic transistor operation (BJTs and MOSFET) as well as passive component circuit analysis.
