Common Interview Questions

  • Q: Why does Android use Zygote for startup? A: State load and SLO assumptions first, identify the first bottleneck, choose scaling and consistency strategy, and explain fallback behavior for partial failures.
  • Q: How does ConnectivityService manage network changes? A: Answer with internals-first reasoning: describe the subsystem boundaries, explain the runtime behavior and bottlenecks, then show how you would validate with traces and measurable latency or memory budgets.
  • Q: How do you debug native crashes from tombstones? A: Answer with internals-first reasoning: describe the subsystem boundaries, explain the runtime behavior and bottlenecks, then show how you would validate with traces and measurable latency or memory budgets.
