Frequently asked questions

How is this different from LeetCode or StrataScratch?

Those platforms focus on isolated problems. Rabbit Hole gives you a complete prep plan matched to your target company's actual interview loop — SQL, stats, product sense, and behavioral — with AI feedback that coaches you through each one.

What companies do you cover?

Meta, Amazon, Google, Uber, DoorDash, Spotify, Netflix, and more. Each company has tailored questions that reflect what they actually ask in their data science interview loops.

Can I try it before paying?

Yes. The SQL module is completely free (no account needed), and a free account gives you one session in each of the other modules. Most users try SQL first, then decide.

How long should I prep?

Most users spend 2-4 weeks working through their prep plan. If you add your interview date, we'll build a paced study schedule so you cover everything in time.

Is this good for beginners?

Yes. The SQL module starts with an adaptive checkpoint that finds your level, then gives you targeted practice. The AI modules are conversational and coach you through each problem step by step.

What is "product sense"?

Product sense is the ability to reason about a product's goals, users, metrics, and tradeoffs. It's a core interview round at Meta, Google, and most top tech companies. Think: how would you measure success for a new feature?
