Data Science Case Studies (2025 Edition)
Digital Product
13Sales

Unlike trivial-style questions, case studies test what actually matters: your ability to break down messy problems, structure your thinking, and communicate solutions that are grounded in data and business context.


These are the kinds of scenarios that you’ll face in product analytics, experimentation, growth, and strategy roles (especially at companies like Meta, Amazon, and Uber).


What's included in the download?

This is a PDF file containing 30+ case studies (mostly from top tech companies), each with a corresponding guide to help you answer them effectively.


Each guide is carefully structured to reflect how real-world data science interviews work and what hiring managers are looking for in the ideal answer.

I truly appreciate the time and insights Andrés has shared with the community. His key points on interview preparation not only highlight his deep expertise but also showcase his exceptional ability to communicate complex ideas in a clear and actionable way. His approach covers everything—from the first HR contact to technical interviews, even within startups and scaleups. It’s rare to find someone who not only understands the nuances of the industry but can also articulate them in a way that adds immediate value.

Andres has been a huge help in my job search. He gave me great advice on improving my CV, which quickly led to two job interviews! We also did a mock interview last week, where he gave me really insightful feedback on my strengths and areas to improve. His advice made me feel way more confident and ready for upcoming interviews. I can't recommend Andres enough if you're looking for a supportive and knowledgeable mentor in data science!
