I met with a recruiter at my college and was given two technical questions. I answered both of these and received a phone call about a week later inviting me out for an on-campus interview. They flew me out the day before the interview and put me in a hotel downtown. I met with an HR person and was escorted to the first of five hiring managers, each one leading to the next. Each hiring manager asked me two to three technical questions, plus one or two soft questions. The whole process took about 3 hours. I felt like I nailed most of the technical questions, but alas, no offer.

Given: three clamped NMOS transistors in series with Vcc at the beginning. The output of the final one went into the source of a PFET, with the drain tied to ground and the gate tied to some voltage. I forget exactly what.

I was asked to label the voltage at each node, and then which state the PFET was in.
