I applied online. I interviewed at Power Integrations in Nov 2022
Interview
1.5 hour with basic technical questions - two interviewers 45 min each including the hiring manager. They walked me through the problems and helped me wherever I faced a block.
Interview questions [1]
Question 1
1. Basic questions around transistors - particularly large W/L ratio ones. 2. A couple of circuits with pmos and nmos in a current mirror configuration - I was asked what would be the node voltages as a function of input to one of the transistor's gate. 3. Layout/cross section of inverter and small signal model of MOSFET
