Common Interview Questions
- Q: When should you use self-hosted runners?
A: Answer with a release-safety flow: deterministic build, automated quality gates, staged rollout, observability thresholds, and a fast rollback path.
- Q: How do matrix builds help Android coverage?
A: State load and SLO assumptions first, identify the first bottleneck, choose scaling and consistency strategy, and explain fallback behavior for partial failures.
