Possible Interview Questions

Can you describe a time when you achieved a significant ARPU increase? What strategies did you use?

In my previous role, I increased ARPU by 20% over two quarters by implementing a tiered subscription model with personalized upsell prompts based on user behavior. I used cohort analysis to identify high-value segments and ran A/B tests on pricing and feature bundles.

How do you use AI tools like Claude in your daily workflow? Provide a specific example.

I use Claude to quickly prototype new engagement features. For instance, I prompted Claude to generate ideas for a retention loop, then refined the concepts and built a functional prototype using no-code tools. This reduced ideation time by 40%.

Describe your process for building a Mixpanel dashboard to track engagement metrics.

I start by defining key metrics like retention rate, session frequency, and conversion funnels. Then I create custom reports and cohorts to segment users by behavior. I set up alerts for significant drops and regularly review the dashboard to identify trends.

How do you prioritize experiments in a backlog? Give an example of a test you ran.

I prioritize based on potential impact and effort. For example, I hypothesized that a simplified onboarding flow would improve retention. I ran an A/B test with a control and variant, measured 7-day retention, and found a 12% improvement, leading to a full rollout.

How do you handle stakeholder management when you need to kill a feature that didn't perform well?

I present data clearly, showing the experiment results and why the feature didn't meet KPIs. I focus on learnings and how they inform future decisions. For example, I once killed a feature after a multivariate test showed no lift, and I used the insights to pivot to a more promising approach.
