I applied online. The process took 1+ week. I interviewed at Linear Technology in Feb 2014
Interview
One of its director contacted me through email. Then we had a phone talk about some general but philosophy questions about analog circuit design. One week's later, I had a phone interview with one of his senior engineers about several technical questions.
Interview questions [1]
Question 1
A circuit like current mirror but quite strange. Because instead of copying current from a diode connected transistor to current source, the circuit intends to copy the current back.
