Explain the platform's users and responsibilities
A platform role needs a clear description of whom the platform serves. An internal developer environment, a customer-facing service and a shared infrastructure foundation create different priorities. Start with the users, the work they need to complete and the responsibilities the platform team owns. This makes it easier to assess whether a candidate's previous experience is relevant to the actual appointment.
Describe the boundary between application teams and the platform team. Who handles incidents, approves changes and decides which capabilities should be standardised? If these boundaries are unsettled, say so. Candidates should not discover after joining that a role presented as product development is mostly an unprioritised support queue. The interview brief should include current constraints as well as the desired future state.
Discuss a change from planning to recovery
Ask the candidate to explain a consequential change they helped deliver. Focus on how they understood the existing system, identified risks, planned the rollout and decided whether to continue. Useful evidence includes how the person checked assumptions and communicated with affected teams. A technically elaborate design is not sufficient if the candidate cannot explain how it could be introduced safely.
Include the recovery decision. Ask what the candidate would do if the change behaved differently from expectations and which signals would matter first. The purpose is to examine practical reasoning, not to demand one preferred architecture. Let the person state assumptions and discuss alternatives. Score the explanation against the environment and responsibility level of the role.
Test the ability to make other teams effective
Platform work is valuable when people can use it. Present a small scenario in which several application teams need the same capability but have different levels of experience. Ask how the candidate would identify the common requirement, design an understandable interface and gather feedback. Look for attention to documentation, support expectations and the cost of maintaining exceptions.
Explore a time when the candidate chose not to build a new platform feature. A useful answer may explain why an existing capability, a process change or clearer guidance addressed the need better. This distinguishes service-minded judgment from a preference for adding technology. It also reveals whether the person can discuss trade-offs with colleagues who do not share their technical specialism.
Match the assessment to the work and operating expectations
A short review of a configuration change, an incident narrative or a design proposal can provide a practical conversation. Keep the materials fictional and self-contained so that no candidate must reveal an employer's sensitive information. Tell candidates which resources they may use and what the panel will evaluate. The exercise should test the role, rather than reward familiarity with an interview puzzle.
Explain operational expectations before the offer stage, including any on-call responsibilities, support coverage and arrangements for escalation. Ask what onboarding would help the person assume ownership responsibly. Bring the assessment back to evidence about dependable change, user needs and collaboration. Tool experience matters where it affects the work, but it should sit inside that broader account of capability.
Frequently asked questions
Should every tool in the current stack be a mandatory requirement?
Only make a tool mandatory when the role genuinely depends on immediate independent use. Distinguish product familiarity from the underlying capability, and identify where a reasonable onboarding period can close a gap.
How can an interview assess incident experience without exposing confidential details?
Ask for an anonymised sequence of decisions, responsibilities and lessons. Avoid requesting system diagrams, customer information or internal incident records from a previous employer.
