Introduction
For a product manager, evaluating operational challenges is a part of the role, particularly in a service-oriented tech company like Lyft. An interview question such as, “Drivers are dropping out of a city on Lyft. How do you figure out what’s going on?” is designed to assess your problem-solving skills. Using frameworks endorsed by ‘Decode and Conquer: Answers to Product Management Interviews,’ we will examine how to structure your response to convey analytical depth and strategic thinking.
Detailed Guide on Framework Application
Choosing the Right Framework
For diagnosing business problems, the 5 Whys Technique—asking “why” five times to get to the root cause—is often effective. Combined with a hypothesis-driven approach, this can help systematically narrow down the potential factors.
Applying the Framework Step-by-Step
- State the Problem: Begin by acknowledging the problem—that there’s a noticeable reduction in Lyft drivers in a particular city.
- Form Hypotheses: Propose potential reasons for the dropout, such as decreased earnings, increased competition, or operational changes.
- The 5 Whys: Apply the 5 Whys technique to each hypothesis to dive deeper into potential causes.
- Data Analysis: Suggest that you would assess data from various sources—surveys, driver forums, ride statistics—to validate your hypotheses.
- Derive Insights: Based on the data, pinpoint the most likely reasons for the driver attrition.
- Action Plan: Propose actionable responses to address the root causes and improve driver retention in that city.
Example Analysis
One hypothesis could be that drivers are leaving due to lowered fares impacting their income. By asking “why” repeatedly, you might uncover a recent policy change that inadvertently incentivized shorter trips, which in turn led to reduced earnings for drivers. Data showing a pattern of shorter trips and feedback from driver forums might confirm this. Consequently, an action plan may involve reevaluating the fare structure or introducing new incentives.
Communicating Effectively
Be methodical in discussing each hypothesis and the associated ‘whys’. Avoid jumping to conclusions without backing them up with data. Remain articulate and logical throughout, showing your comprehension of complex ecosystems and the interplay of different factors.
Conclusion
Investigating a sudden change in a business metric such as driver attrition requires a structured and evidence-driven approach. Applying the 5 Whys and forming hypotheses help uncover the root causes, validating them with data. Being systematic in your analysis and communication is key to crafting a compelling narrative in your response to problems during a product manager interview. Practice this approach to problem-solving questions to demonstrate your readiness for tackling real-world challenges at a FAANG company.
