6 questions

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

  1. 1

    How do you design reporting so that a failure tells you why, not just that it failed?

    mediumFramework

    A strong answer covers

    Attach screenshot, console and network logs, test data id, build and environment, and step names in business language. Group failures by cause.

  2. 2

    After a UI action you must verify the database state. How do you do it safely?

    mediumDatabase

    A strong answer covers

    Read-only credentials, query by a unique key created in the test, wait with a bounded poll, never depend on row order, and clean up through the app or API.

  3. 3

    A test fails once in fifty runs. Walk through your approach.

    hardDebugging

    A strong answer covers

    Capture state on failure, run it in a loop locally, add structured logs, look for shared data, timing, ordering and resource limits. Fix the cause, then prove it with a long run.

  4. 4

    How do you test an API that is paginated and sorted?

    mediumAPI testing

    A strong answer covers

    First, last and middle pages, page size limits, stable sort with ties, adding or deleting while paging, invalid cursors, and total count consistency.

  5. 5

    Write a function that finds duplicate records in a list of dicts by a key and explain how you would test it.

    mediumPython or Java

    A strong answer covers

    Use a set or counter keyed on the field, return the repeats. Tests: empty, none, all duplicates, missing key, differing case, large input.

  6. 6

    What should a pull request check run for a test repository?

    mediumCI/CD

    A strong answer covers

    Lint, unit tests for helpers, a smoke subset, and a dry-run of the suite collection. Fast enough that people wait for it.

Now say it to an interviewer

Reading a guide is not the same as answering under a clock. Run a mock interview and get scored feedback.
