Growth PM Interview Questions: Tools
Common questions about PM tools for Growth PM interviews, with sample answers and coaching notes on what interviewers are actually evaluating.
Q1: “Walk me through your analytics stack. What tools do you use and why?”
“Event tracking in Amplitude or Mixpanel for product analytics, with a data warehouse (BigQuery or Redshift) as the source of truth for anything complex. Session replay in FullStory for qualitative debugging. A/B testing in a dedicated tool like Statsig or Optimizely rather than rolling our own. The key is keeping the stack minimal — every tool adds instrumentation debt.”
Q2: “How do you decide when to use a dedicated A/B testing tool vs. a feature flag system?”
“Feature flags are for deployment control and gradual rollout. A/B testing tools are for measurement with statistical rigour. The overlap is when you're using flags to split traffic and track outcomes — which works, but you lose guardrail metrics and automatic significance calculation. For anything where the business decision depends on the result, I want a proper testing tool.”
