Systems Design Engineer Interview Questions

269 systems design engineer interview questions shared by candidates

Q: You have two diodes, how do you design AND & OR gate using those? - What do you understand by fan-out? * (Discussion of fan-out went on for at least 15-20 minutes. The questions that followed were based on the replies that I gave. It's quite similar to a viva you see!) - On what parameters does fan-out depend? Does it only depend on current? - Can you relate fan-out with input impedance/ capacitance? - Do you choose FET over BJT for the reason that it has higher input impedance or on basis of some other parameter and input impedance of FET just happens to be high? - Does fan-out depend on frequency? - If frequency is kept same and the input capacitance is varied, what effect would you see on the circuit?

Some basic questions/tasks about C programming (pointers, arrays..), design task for receiving data bytes from the transmitter (C programming), Asked to explain different parts of some old SOC configuration. For people studying only Electronics I would suggest going through Software Engineering lectures from other courses to know about how memory is managed in a SOC and CPU. Ideally read about the Architecture of CPU and Microcontrollers as I was asked this in all 3 Interviews with ARM. I only studied Electronics and had no courses related to this except when we briefly looked into simple microcontrollers without going into detail so it was good decision going through Software Engineering course notes before the interview.
