Not easy but not too hard basic cyber question about CIA, PKI, Powershell and automation and Linux and Networking. Use the STAR method (talk about the situation, task you completed, actions to resolve the task and resolution to the problem).

All technical questions, how would you harden a Linux system, tell me about this project, how have you applied the SDLC to your projects, agile methodology experience, troubleshooting, etc. No behavioral questions - only technical, so be prepared.
