6 questions

Answer out loud first, then open the guide. Most people read the guide too early.

  1. 1

    How do you write a test strategy for an enterprise platform migration?

    mediumStrategy

    A strong answer covers

    Scope and risks, data migration validation, parallel run and reconciliation, performance and cut-over rehearsal, rollback plan, sign-off criteria, and who decides go or no-go.

  2. 2

    How do you prove migrated data is complete and correct?

    hardData

    A strong answer covers

    Row counts, control totals, field-level sampling with rules, referential integrity checks, edge records, and a reconciliation report that a business owner signs.

  3. 3

    What metrics would you show a steering committee, and which would you avoid?

    mediumGovernance

    A strong answer covers

    Risk coverage, defects by severity and age, escaped defects, readiness for go-live. Avoid raw test case counts and bare pass percentages without context.

  4. 4

    How do you test a configuration-heavy enterprise system where most behaviour is set up, not coded?

    mediumPlatform

    A strong answer covers

    Test configuration as data, cover each business rule combination, check role and permission matrices, and verify after every config promotion between environments.

  5. 5

    A senior stakeholder wants to cut testing time to save the date. How do you respond?

    mediumCommunication

    A strong answer covers

    Offer a risk-ranked scope with what is dropped and what could happen, let them choose, and record the decision.

  6. 6

    Which tests would you automate for a system that gets a major vendor upgrade twice a year?

    mediumAutomation

    A strong answer covers

    A stable regression of core business flows and integrations, data-driven where rules vary, and a quick compatibility check of customisations after each upgrade.
