How can I effectively test a candidate’s writing and communication skills for a sysadmin role?

One effective way to assess communication skills is to have candidates complete a live writing task. You can present them with a problem and ask how they would document the solution in your internal ticketing system. If there isn’t an existing knowledge base or workflow, see how they would outline their approach. Consider flipping a screen share on and having them write in real time. This allows you to see their thought process and writing skills firsthand.

While resumes can be misleading, I find that asking behavioral questions in an interview helps gauge communication skills. Try to present them with scenarios and ask how they would articulate solutions or updates to a team or customer. A live video call can make it easier to assess their ability on the spot.

I’ve had success with a practical test that involves having candidates create a solution document based on a common issue in your field. This way, you can assess not just their ability to communicate but also their understanding of documentation protocols and structured problem-solving.

From my experience, candidates often excel at following documentation rather than creating their own. It's not uncommon for the 'needful' types to ghost after they get hired, too. If they do show up, a solid test at the hiring stage is crucial.
