Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
Tell me about a problem where you had to write a clear problem statement, compare options, and get a plan approved before you could act.
What they are checking: Whether they slow down to define the problem and weigh alternatives, which this role asks for in writing.
Tell me about a time you documented something so well that someone else could support it without calling you.
What they are checking: Whether they see documentation as part of the job, which matters on a team that hands off support across shifts.
Tell me about an outage you helped resolve. What did you change afterward so it would not happen again?
What they are checking: Whether they follow through on root cause and prevention, which is the core of reliability work.
What would you do
A business team asks for new servers by Friday, but their requirements are vague. How do you handle that conversation?
What they are checking: Whether they can draw out real requirements from customers and push back politely on a deadline that hides risk.
During market hours, a server you maintain throws errors but the business says not to restart it. What do you do?
What they are checking: Whether they can weigh business risk against technical risk and find a safe path when the obvious fix is off the table.
About the work
Walk me through how you'd use SCCM to push a patch to a few thousand Windows servers without taking down anything that supports trading.
What they are checking: Whether they stage deployments, use collections and maintenance windows, and plan a rollback before touching production.
A group policy change in Active Directory starts locking users out across one site. How do you find the cause and fix it?
What they are checking: Whether they know how GPO precedence, replication and scope work well enough to isolate a change under pressure.
An application on a clustered Windows server is slow, but CPU and memory look fine. Where do you look next?
What they are checking: Whether they understand how disk, network, virtualization and the app itself interact, rather than stopping at the obvious counters.
What's a manual task you automated with PowerShell or another script, and how did you validate it before trusting it in production?
What they are checking: Whether they treat automation as code that needs testing, not a quick fix that can quietly break things at scale.
How do you decide whether a workload belongs on Windows, Linux or OpenShift when a team asks for new infrastructure?
What they are checking: Whether they can match platform choice to the app's real needs instead of defaulting to what they know best.
How do you think about security when you configure a new Windows server for a market-facing environment?
What they are checking: Whether hardening, least privilege and patching are built into their default build rather than added later.
