Behavioral practice
Google behavioral practice
6 prompts drawn from real Google loops. Each one maps to a leadership principle and includes a rubric reviewers actually use.
STAR method
Tell every behavioral story like an engineer
Use this scaffold to keep answers crisp, specific, and outcome-driven.
Situation
Set the scene with concrete context — when, where, who, scale.
“In Q3 our checkout had a 4.2s p95 on mobile, hurting conversion for 2M weekly users.”
Task
Frame the goal or problem you owned, and the constraints.
“As tech lead, I had two weeks to land a fix before peak sale, with no UX regressions.”
Action
Walk through what you specifically did — your decisions, not the team's.
“I profiled bundles, split the cart route, deferred non-critical SDKs, and added a perf budget in CI.”
Result
Quantify the impact — numbers, learnings, and what changed long-term.
“p95 dropped to 1.6s, conversion lifted 7.4%, and the perf budget became team-wide policy.”
Practice prompts
Describe a disagreement you had with a teammate about a technical approach. How did you resolve it?
Tell me about a significant failure. What happened and what did you change afterward?
Give an example of how you influenced a decision or outcome without having formal authority.
Walk me through a time you had to make an important decision quickly with limited data.
Tell me about a time you proactively improved something that nobody asked you to fix.
