Fewer, harder problems.
The ones top funds
actually ask.
The prep books are outdated. The forums are unverified. Epigram is built for one thing: the exact problems top funds actually ask, at the difficulty they actually ask them.

From the founder
“I was preparing for top quant fund interviews. I had the mathematical background. I read the books everyone reads. And they felt like practice for a different exam. Too easy. Too broad. No way to tell which problems actually mattered. I spent hours on material that wasn't going to appear in the room — and I couldn't shake the feeling that my prep wasn't mapping to what I was about to face. I built Epigram because that resource shouldn't be this hard to find.”

The problem with current resources
Every other resource was built for a different exam.
The quant interview has evolved. The prep landscape hasn't. What's out there is scattered, outdated, or built for the wrong problem type entirely.
✕ Heard on the Street
"Too many questions. No emphasis on what actually matters."
500+ problems with no signal for what to prioritize. You can finish it and still not know which topics firms weight most heavily.
✕ The Green Book (2008)
"Answers scattered. Not self-contained. Calibrated too low."
Written for solid undergrad math — not for what Citadel puts in front of you. The problems that matter aren't in this book.
✕ Glassdoor & forums
Real questions exist somewhere. Finding them doesn't help you.
Scattered across thousands of threads with no explanation of what the interviewer was testing. Fragments, not a curriculum.
✕ AI-generated explanations
Wrong answers, delivered with total confidence.
ChatGPT and similar tools frequently produce incorrect solutions to hard quant problems. You won't know the difference until you're in the room. Every Epigram solution is human-verified by a Math PhD.
Our Flagship Product
One month from now, you could walk into any quant interview ready.
Most candidates walk into a quant interview hoping the right problems come up. You won't need to hope.
The Four-Week Intensive takes you through every topic top firms test — probability, stochastics, statistics, game theory, etc. — and deeper into the firm-specific problems the standard books never reach. Coding woven throughout, the way quant interviews actually work: math and code tested together, not siloed.
29 topics. ~180 curated problems. Four weeks from where you are now to ready.

What's Inside
Curated to what top funds test.
Nothing more. Nothing less.
The ones that appear in top fund interviews, at the difficulty they appear at, in the sequence that builds the right mental models.
