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

2. Talk me through how you plan a corrective work order from the moment a request is raised to closure.

Why they ask: To test the core planning process and your discipline in following it.

Why they ask: To test analysis and prioritisation skills in a common maintenance problem.

A sample answer to question 1

How would you describe the role of a maintenance planner, and how does it differ from the role of a scheduler or supervisor?

A planner prepares work so that when an engineer picks it up, everything they need is ready. That means scoping the job, writing the job plan with steps, tools and safety requirements, estimating labour hours by trade, identifying parts and kitting them, and arranging permits, access and any contractors. A scheduler then takes ready-to-go work and slots it into the weekly programme according to priority, shutdown windows and available labour. The supervisor directs people on the day and deals with the unexpected. In practice at many sites the roles overlap, so I'd be doing some of each. The purpose is to increase wrench time, the share of the shift spent actually fixing things, rather than hunting for parts or waiting for isolations. Good planning also drives down emergency work, because tasks get done at the right time, before they turn into breakdowns. I'd see myself as the bridge between operations, stores and the tradespeople.

Common mistake to avoid: Describing it as only data entry; confusing planning with supervision
