I applied online. The process took 3 weeks. I interviewed at Garrett Metal Detectors
Interview
A technical phone interview was given concerning analog electronics concepts. The employees administering it were very nice! This was a long time ago, so the interview process might be different now.
Interview questions [1]
Question 1
Common analog electronics questions such as the construction of low/high pass filters, different op-amp setups (differentiation, inverting, etc).
