Summary

PM interview at Google with a single product analytics question about handling low survey response rates. Pretty short session from what I can tell, but the question itself had some depth to it.

Q1

You're running a user survey and you can't get enough respondents. What do you do?

I went straight to incentives and sample size math, which felt too surface-level in retrospect.

Suggested Approach

Start by clarifying the survey's goal and target audience, then diagnose why response rates are low (e.g., poor targeting, survey fatigue, lack of incentives). Propose a structured plan that includes both quick wins and long-term improvements, and emphasize iterative testing and measurement of response rates.

Pro tip: Frame your answer around the trade-off between statistical significance and speed: sometimes a smaller, well-targeted sample with higher response quality beats a large, noisy one. Show you can make pragmatic decisions under ambiguity.

1. Clarify the Goal and Constraints

Ask clarifying questions to understand the survey's purpose, target population, desired sample size, and timeline. This ensures you're solving the right problem.

2. Diagnose the Root Cause

Identify why respondents are lacking: Is the survey too long? Is the audience wrong? Are there no incentives? Use data (e.g., open rates, drop-off points) to pinpoint issues.

3. Brainstorm and Prioritize Solutions

Generate a list of tactics (e.g., incentives, shorter surveys, multi-channel outreach, targeted sampling) and prioritize based on impact and effort.

4. Implement and Test

Run small experiments (A/B tests) to validate the most promising tactics, measuring response rate lift and cost per response.

5. Measure, Learn, and Iterate

Track key metrics (response rate, completion rate, data quality) and iterate. If needed, adjust the survey design or sampling strategy.

Key Points to Mention

  • Define the target audience and sampling frame to ensure representativeness.
  • Consider incentives (monetary or non-monetary) and their impact on response bias.
  • Optimize survey design: length, question wording, mobile-friendliness.
  • Leverage multiple channels (email, in-app, social media, panels) to reach users.
  • Use A/B testing to compare outreach methods and messaging.
  • Balance statistical rigor with practical constraints (time, budget).
