What people say after working with me

Candidates often find themselves patching together fragmented blog posts, outdated practice problems, and scattered frameworks. It’s inefficient and incredibly frustrating. I was hand-curating learning guides for my clients and was contemplating writing a comprehensive guide myself. Thankfully, Jonathan just solved this problem.

Yes, it’s a premium resource. But considering it distills the hard-fought patterns of 80+ actual interview rounds into an actionable blueprint, the ROI is a no-brainer. Land just one strong offer, and this pays for itself on day one.

Jonathan’s interview playbook helped me tremendously in how I view the interview process and prepare for it. Personally, I got the most out of the course through three things:

1. A thought framework with clear logic flow that starts simple and adds one layer at a time, building both depth and breadth into case study answers;
2. A breakdown of what each interview round includes and how to prepare for it, including with AI;
3. A list of requirements from junior to staff level, showing what to focus on based on your level and where to pivot to show depth during interviews.

I am truly grateful for Jonathan’s course as it helped me pass my very first final round and land my dream offer. If you’re looking to prepare thoroughly and feel confident going in, but aren’t sure whom to ask or where to start, this is a great investment.

A single session with Jonathan was worth more than 20 hours of studying for interviews. He walked me through interview structures and where to focus (and not to focus). Ultimately Jonathan helped me secure two offers, and the only thing I’d do differently is make sure I reached out sooner.

I had the pleasure of being coached by Jonathan on experimentation and causal inference, and I can’t recommend him highly enough. He is incredibly knowledgeable and thoughtful, and he asks the most relevant and insightful interview-style questions that really stretch your thinking. What stood out most was the level of detail in his feedback. He didn’t just point out areas for improvement but explained why and how to approach them differently, which made a huge impact on my preparation.

Thanks to Jonathan’s coaching, I felt very prepared and confident going into my interviews, and I ultimately received strong positive feedback on the experimentation and causal inference rounds. His guidance was instrumental to my success, and I’m deeply grateful for his support.

Jonathan is the best data science coach I know, and he was very important in preparing me for my interviews at Uber.
