A week before
Start with the vacancy. Mark the responsibilities and priorities that you can address with direct evidence from your own work. Build a small bank of truthful examples rather than memorising scripts. For each one, note the setting, the decision you faced, what you personally did, the result and what you learnt.
Review your Test Manager CV beside the job description. Check that its dates, scope and outcomes match what you plan to say. Read your Test Manager cover letter too, since you should be ready to explain any claim or motivation you included.
Practise aloud. Open with a direct answer, add only enough context to make the example clear, then explain your actions and the outcome. If the invitation mentions a task, work from the instructions supplied by the employer. Ask the named contact if the objective, timing or permitted materials are unclear.
The day before
Confirm the time, address, travel plan and contact details. Put requested documents and permitted notes together. For an in-person interview, allow extra travel time. If your interview is remote, test your device, camera, microphone, connection and meeting link in the room you intend to use.
Prepare questions about the actual post, including its immediate priorities, reporting lines and next steps. If pay may come up, read the UK Test Manager salary guide and decide what you need to ask. Do not rely on a single figure without considering the scope of this vacancy.
On the day
Listen to the whole question before choosing an example. Use notes as prompts rather than a script, and make your own contribution clear without taking credit for the wider team's work. If you do not understand a question or task instruction, ask for clarification. Leave enough time to ask your prepared questions and record any promised next steps.
