Most Infrastructure Manager interviews in the UK follow a pattern, and knowing it beats guessing. Below are eight questions from our bank of 12, each with a note on what the interviewer is really after.

Eight Infrastructure Manager interview questions, and what the interviewer is thinking

1. What do you see as the main responsibilities of an Infrastructure Manager, and what sort of leader are you in that role?

Why they ask: They want to see that you understand the balance between delivery, risk, people and cost at manager level.

2. How would you build an infrastructure roadmap and decide what to refresh or modernise first when there is a lot of technical debt?

Why they ask: Managers must prioritise limited budget and capacity using risk and business value.

3. How do you run major incident management, and how do you make sure the same incidents do not keep recurring?

Why they ask: They want to see you can lead through ITIL-style processes, not just fix faults.

4. One of your best engineers tells you they are exhausted from the on-call rota and is thinking of leaving. What do you do?

Why they ask: They are testing people management, empathy and your ability to fix root causes in team structures.

5. How do you make sure your infrastructure meets security and compliance standards such as Cyber Essentials Plus or ISO 27001, while still keeping delivery moving?

Why they ask: Managers are accountable for control effectiveness and audit readiness.

6. Tell me about a time you led a team through a significant change, such as a migration, restructure or new way of working.

Why they ask: They want evidence of leadership through change, including bringing people along.

7. The finance director asks you to cut your infrastructure budget by 15 per cent this year. How do you respond?

Why they ask: They are testing commercial judgement and the ability to negotiate and protect resilience.

8. How would you decide between running a service on-premises, in a public cloud or through a managed service provider?

Why they ask: Strategic technology decisions require structured trade-off analysis, not trends.

A sample answer to question 1

What do you see as the main responsibilities of an Infrastructure Manager, and what sort of leader are you in that role?

The role is about keeping the technology foundations reliable, secure and affordable while enabling the business to change. That covers servers, storage, networks, cloud platforms, end-user compute and the teams who run them. My responsibilities would include setting the infrastructure roadmap, owning availability and recovery targets, managing the budget and key suppliers, making sure we meet standards like Cyber Essentials Plus or ISO 27001, and leading major incident response. Equally, it is about people: building a team that can handle on-call, develop skills and automate rather than firefight. As a leader, I try to set clear priorities, delegate properly and trust engineers with ownership while being visible in incidents. I translate technical risk into business language for executives, and I believe in blameless reviews, because they make teams more honest and the service more resilient.

Common mistake to avoid: Describing only technical tasks; No mention of team development
