How to Ace Your Product Management Interview: Improving Existing Products

This blog post is tailored for product managers preparing for interviews with top tech companies, focusing on questions relating to improving existing products like Robinhood. We will use frameworks from ‘Decode and Conquer’ to structure our answer effectively.

Detailed Guide on Framework Application

1. Choosing the Appropriate Framework

The CIRCLES Method™, a PM interview framework formulated by Lewis C. Lin, is well-suited for product improvement questions. It stands for Comprehend, Identify the customer, Report the customer need, Cut through prioritization, List solutions, Evaluate tradeoffs, and Summarize your recommendation.

2. Step-by-Step Guide Using CIRCLES Method™

1. Comprehend: Start by understanding the scope of the product and specific issues that are faced by its users.
2. Identify the customer: Define the user demographic and their needs.
3. Report the customer need: Articulate the needs and pain points of the identified users.
4. Cut through prioritization: Prioritize issues based on their impact and the company’s goals.
5. List solutions: Brainstorm potential improvements or features.
6. Evaluate tradeoffs: Consider the cost, implementation time, and potential risks of each solution.
7. Summarize your recommendation: Conclude with your top recommendation based on the evaluation.

3. Hypothetical Example Application of the Framework

Utilizing the CIRCLES Method™, let’s propose an enhancement for Robinhood:

1. Comprehend: “Robinhood aims to make the stock market more accessible, but users have highlighted issues related to real-time data display and educational content.”
2. Identify the customer: “The primary users are millennials who are tech-savvy and prefer straightforward, educational trading platforms.”
3. Report the customer need: “These users need accurate, real-time information and resources to make informed trading decisions.”
4. Cut through prioritization: “Real-time data is crucial for trading; therefore, improving data reliability should be the priority.”
5. List solutions: “One solution could be to integrate a more robust data engine to ensure accuracy and speed.”
6. Evaluate tradeoffs: “While this solution may be costly and require time to implement, the long-term benefit is a more trustworthy platform that retains users.”
7. Summarize your recommendation: “My recommendation is to focus on upgrading the data engine while simultaneously rolling out better educational content to ensure user loyalty and platform integrity.”

4. Fact-checks and Reality Adjustments

Confirm the issues and needs through user feedback, data analysis, and market research. Reality-check solutions against the current technological landscape and the company’s capabilities.

5. Effective Communication Tips

When discussing product improvements, be clear and concise in conveying the need for change. Justify your prioritization and recommendations with solid reasoning and be prepared to discuss alternatives. Your ability to think strategically and make informed decisions is crucial.
