Frequently asked questions

What is the difference between BDD and TDD? Interviewers want to know you understand the methodology and collaboration model, not just the tool.

Cucumber for Java / JavaScript / Python / Ruby teams. SpecFlow for C# / .NET. Both use the same Gherkin syntax, so the BDD skills transfer.

For an experienced QA engineer: 1–2 weeks to productive, 2–4 weeks to advanced patterns like hooks, DI and parallel execution.

Yes — Cucumber steps can invoke performance tests, security scans or accessibility checks. Just wrap the call in a step definition.

Cucumber uses Gherkin specifications; JUnit uses Java annotations. They're complementary — JUnit for unit tests, Cucumber for acceptance tests on top of a JUnit runner.

Yes — for teams with strong business + engineering collaboration. Without the Three Amigos discovery workshop, BDD often becomes overhead.

  • Master the fundamentals before tackling advanced Cucumber BDD scenarios.
  • Always explain trade-offs — interviewers reward judgement, not memorisation.
  • Use real project examples; generic answers blend in.
  • Practice answers out loud — written prep doesn't transfer to live rounds.
  • Revise the 30-second cheat sheet the night before your interview.
  • Keep one strong scenario story ready for every section above.
