The new way to get ready for data science interviews
Job interview prep material and employee training courses that include product case studies, data science take-home challenges, and AI-powered apps.
Gain inside knowledge by reverse-engineering what happens inside top tech companies.
“ This material helped me so much get a data scientist job at Facebook ”
Real Data Science
Practice in advance on challenges just like the ones you will get in the interview, resembling what you will actually do at work
PRODUCT CASE STUDIES
Learn how to answer the hardest product, metric, A/B testing on-site questions. Such as: Should we add a given new feature?, Which metric would you choose for this new feature?, etc.

I have been creating educational material related to data science since 2015. Firstly focusing on job interviews (A Collection of Data Science Take-Home Challenges, 40 Data Science Product Questions, DS Coding Course) and, more recently, on employee training (Full Course in Product Data Science and AI for Data Scientists).
The main idea behind all the material is to simulate the actual work data scientists do in top tech companies.
In 2023, I built and sold a Chatgpt app to Colgate, I created a practical Chatgpt course to help people build their own app, and built the DataScienceGPT app.
Prior to all this, I worked as a data scientist for several Silicon Valley tech companies, the last one being Airbnb.
“ Giulio is an excellent advisor for preparing for interviews. Very recommended. ”
