Summary

PM interview at Truecaller, product sense round. One question but it had a lot of surface area and I don't think I handled the scoping part well.

You're a PM at a major messaging app tasked with increasing user engagement. What features would you build and how would you prioritize and evaluate them?

I jumped straight into features without nailing down what 'engagement' actually meant for the product, which I think hurt me.

Suggested Approach

Start by clarifying the goal and defining engagement metrics for Truecaller's messaging app. Then propose 2-3 features that address user needs and business goals, prioritize them using a framework like RICE, and outline an A/B testing plan to evaluate their impact.

Pro tip: Tie every feature to a specific engagement metric and consider Truecaller's unique value proposition of spam detection and caller ID to differentiate from other messaging apps.

1. Clarify Goal & Metrics

Define what 'engagement' means for Truecaller's messaging app (e.g., DAU/MAU, messages sent per user, retention) and align with business objectives.

2. Ideate Features

Brainstorm features that leverage Truecaller's strengths (spam detection, caller ID) and address user pain points, such as smart replies, spam-free group chats, or integrated caller ID in chats.

3. Prioritize with Framework

Use a prioritization framework like RICE (Reach, Impact, Confidence, Effort) to rank features based on potential impact and feasibility.

4. Define Experimentation Plan

Outline A/B tests with clear hypotheses, success metrics, and sample sizes to measure the impact of each feature on engagement.

5. Evaluate & Iterate

Analyze results, learn from failures, and iterate on features to continuously improve engagement.

Key Points to Mention

  • Leverage Truecaller's unique spam detection and caller ID capabilities to enhance messaging experience.
  • Define clear engagement metrics (e.g., DAU/MAU, messages per user, retention rate) before proposing features.
  • Use a prioritization framework like RICE to objectively rank features.
  • Design A/B tests with control and treatment groups, ensuring statistical significance.
  • Consider potential trade-offs, such as privacy concerns with spam detection in messages.
  • Align features with business goals, such as increasing ad revenue or premium subscriptions.
