NVIDIA interview questions

Pretty bare bones. We skipped the niceties and went straight into the technical questions. The usual screening stuff. Figure out voltage of circuit of caps in series. Threshold voltage stuff. Transistor sizing, region of operations etc. The questions the interviewer asked made me feel he was more interested in phishing for info about design practices at my current job. He didn't sound too interested about other things, and I didn't feel comfortable with this indifferent approach. Not very personable and didn't sound like someone I would want to work for.
