Systems Software Engineer Interview Questions

576 systems software engineer interview questions shared by candidates

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.

What is IPC? What is RPC? (this was great, the interviewer had an accent so I was confused with the previous question) Questions about linux kernel such as difference between block device vs character device what is volatile keyword? what is static keyword? what do you want to do? what is an interrupt? how to handle interrupt?
