Maintenance Manager Interview Questions UK: 8 Real Questions and What Interviewers Want

Before your Maintenance Manager interview, it helps to see the questions from the interviewer's side. We have picked eight from our set of 16 and added the reason each one gets asked.

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

1. How would you carry out an asset criticality analysis and use reliability-centred maintenance to set a maintenance strategy?

Why they ask: A maintenance manager has to focus limited resources where failure matters most, so they test your method.

2. How do you build a maintenance budget, and how do you justify it to senior management?

Why they ask: They want to know you can manage money and speak the language of the finance director.

3. How do you decide what spare parts to hold, and how do you manage the stores inventory?

Why they ask: Spares policy balances downtime risk against cash tied up, and it shows commercial judgement.

4. What is Total Productive Maintenance, and how would you introduce autonomous maintenance on a site that has never used it?

Why they ask: TPM is a well-known improvement framework, and they want a realistic approach to engaging operators.

5. How do you plan and run a major shutdown or turnaround so that it finishes on time, safely and within budget?

Why they ask: Shutdowns are high-risk, high-cost events, and they want to see structured planning.

6. A major unplanned breakdown has cost the business two days of production, and the managing director demands to know why it happened and what you will do. How do you respond?

Why they ask: They want to see accountability, structured investigation and clear communication under scrutiny.

7. Tell me about a time you reduced downtime or maintenance costs significantly, and how you achieved it.

Why they ask: They want a measurable result and a clear explanation of what you personally did.

8. What does a maintenance manager do, and what attracts you to the role?

Why they ask: They want to understand your view of the role's breadth and whether you are committed to it.

A sample answer to question 1

How would you carry out an asset criticality analysis and use reliability-centred maintenance to set a maintenance strategy?

I start with a register of all assets, then score each one on the consequence of failure: safety, environment, production loss, quality, repair cost and legal compliance, against the likelihood and how quickly we could recover. That gives a criticality ranking, so a spare pump with a standby has a very different status from a single-point-of-failure compressor. For the most critical assets, I apply reliability-centred maintenance, working with operators and technicians in a structured session. For each function, we list how it can fail, the cause and the effect, and choose the most cost-effective task: condition monitoring where failure shows warning signs, time-based servicing where wear is predictable, a redesign if the failure cannot be managed, or run-to-failure where the consequence is low and a spare is available. The output is a task list linked to the planned maintenance system. I review it with failure data from the CMMS, so the strategy keeps improving.

Common mistake to avoid: Treating every asset equally; running RCM without operator input
