Who is this System Administrator interview plan for?

It is written for the interviewer, not the candidate: the hiring manager, engineer or panel member running the Technical Interview round for a System Administrator role. It gives you a 60 min script to follow in the conversation — 8 questions with what each one is for and the signals to score against — so you are not writing the round from scratch the night before.

What does the Technical Interview round assess?

This round is focused on: System Administration, OS Knowledge, Linux/Unix, Windows Server, Virtualization. It works through Introduction, System Administration and OS Knowledge, Linux/Unix and Windows Server, Virtualization and Problem-solving and Closing, scoring against 54 observable signals, with follow-up prompts on all 8 questions for going deeper where an answer is thin.

How is the 60 min split up?

Introduction (5 min), System Administration and OS Knowledge (15 min), Linux/Unix and Windows Server (15 min), Virtualization and Problem-solving (15 min), Closing (5 min). The timings are there so the round stays on schedule and every candidate gets the same shape of interview — which is what makes two candidates comparable afterwards.

What other rounds should I run for a System Administrator?

A single round does not cover a whole role. The other rounds in this library for a System Administrator are Behavioral Interview, Infrastructure Q&A, Problem-solving Test, Scenario-based Questions and System Troubleshooting Test. Each is a separate plan you can use as it is.
