This is the kind of question where you think you have a good story ready and then halfway through telling it you realize it doesn't actually show what they want.
Use the STAR method to describe a specific experiment where the results contradicted your hypothesis. Focus on the actions you took to diagnose the root cause, the data-driven decisions you made, and the lessons learned that improved future experiments.
Pro tip: Emphasize how you communicated the unexpected results to stakeholders and turned the surprise into a learning opportunity that influenced product strategy. Show that you embrace failure as a path to innovation, aligning with Amazon's culture of experimentation.
Briefly describe the experiment, your hypothesis, and the expected outcome. Provide enough background to understand why the result was surprising.
Clearly state what actually happened, including key metrics and how they deviated from your prediction. Highlight the impact on the product or business.
Explain the steps you took to investigate the root cause, such as segmenting data, checking for confounding variables, or running follow-up tests.
Describe the decisions you made based on the findings, such as pivoting the strategy, iterating on the experiment, or communicating with stakeholders.
Summarize the key lessons learned and how you applied them to future experiments or shared them with your team to improve processes.
