Quantify impact of your projects using STAR

Interview-style behavioral prompt:

"Pick one or two of your impactful projects and walk me through them in detail. Focus on what you did and how you measured success."

Structure your answer using the STAR method, with particular emphasis on quantifying results:

• Situation : Briefly describe the context, scale, and importance of the project.
• Task : Your specific responsibilities and goals.
• Action : The concrete technical and non-technical steps you took.
• Result : Quantify impact where possible, such as:
  • Performance gains (latency, throughput improvements).
  • Reliability gains (reduced incident count, MTTR, error rate).
  • Productivity gains (build times, deployment frequency, fewer manual steps).
  • Business metrics (revenue, conversion rate, retention, cost savings).

Prepare at least one example where you can give specific numbers (even approximate), and be ready to explain how you obtained or estimated those metrics.
