Common Interview Questions

  • Q: What happens inside ART at runtime? 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: What tradeoffs came with scoped storage? 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 SurfaceFlinger stalls appear as jank? 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.
