Summary

Product sense round for a Data Scientist role at TikTok where they basically handed me a blank canvas and said 'you use TikTok, what's broken, fix it.' Felt open-ended in a way that was either freeing or terrifying depending on how prepared you are.

Questions Asked (1)

Q1

You're a regular TikTok user. What parts of the product frustrate you, and what concrete changes would you make? Walk through the expected impact on users and on the business.

I went straight to the algorithm and content relevance angle because that felt safest, but looking back I spread myself too thin.

Suggested Approach

Pick one or two specific frustrations that are well-aligned with TikTok's core metrics (e.g., engagement, retention, monetization) and that you can quantify. For each, propose a concrete product change, then walk through the expected impact on users and business using a structured framework. Show that you can balance user experience with business goals and that you can measure success with clear metrics.

Pro tip: Anchor your answer in TikTok's North Star metric (e.g., daily active users or time spent) and explicitly discuss trade-offs, such as short-term revenue loss for long-term retention gains. This demonstrates product maturity and data-driven thinking.

1. Identify a specific frustration

Choose one or two genuine user pain points that are relevant to TikTok's product and that you can support with personal experience or data. Avoid generic complaints; focus on issues that affect key metrics.

2. Propose a concrete change

Describe a specific, actionable product change that addresses the frustration. Be clear about what the change is, how it would work, and why it's feasible.

3. Analyze user impact

Explain how the change would affect user behavior, satisfaction, and engagement. Consider both intended and unintended consequences, and how you would measure the impact (e.g., A/B test metrics).

4. Analyze business impact

Discuss how the change would affect TikTok's business metrics, such as retention, monetization, and content ecosystem health. Quantify where possible and acknowledge trade-offs.

5. Prioritize and measure

Summarize why this change is worth prioritizing over others, and outline how you would validate success with data (e.g., key metrics, experiment design).

Key Points to Mention

  • Alignment with TikTok's core metrics: DAU, time spent, retention, and revenue.
  • Use of data to validate the frustration (e.g., personal experience, user reviews, internal metrics).
  • Concrete product change with clear implementation details.
  • Expected impact on user engagement and satisfaction, with potential metrics to track.
  • Business impact, including trade-offs between user experience and monetization.
  • How to measure success: A/B testing, guardrail metrics, and long-term retention.
