System Administrator Interview Questions

System Administrators are responsible for the proper operation of the company’s IT systems, including hardware, software and network.

SysAdmins are usually the first point of contact, so candidates need to combine excellent troubleshooting skills with an ability to explain technical details to a non-technical audience. During your interviews, test candidates for their knowledge of IT system best practices.

For this role, future SysAdmins will deal with various issues (e.g. backing up and recovering data, upgrading servers and installing applications), so it’s best to choose candidates with broad technical backgrounds. Keep an eye out for system administrator candidates who are passionate about the IT field and enjoy continuous learning. Many of these questions work well for a windows system admin role.
