Why I Built IB Interview Questions
After completing my Master in Finance at ESSEC (#4 globally - Financial Times 2025) and working in VC, then M&A at Clipperton (leading tech M&A boutique based in Paris), I made a choice: leave finance to build something that actually helps people.
But I couldn't shake one frustration from my recruiting days - interview prep was broken. My classmates and I were drowning in:
- Static PDFs we couldn't track progress on
- $300+ guides with outdated questions
- No way to practice on the subway or between classes
- Zero feedback on whether our answers were actually good
The most successful candidates weren't necessarily the smartest - they were the ones who practiced consistently. But the tools made that nearly impossible.

From Frustration to Innovation
I combined two things:
1. What I knew: IB and PE interviews, having gone through them myself and watched dozens of friends navigate BB and EB processes
2. What I loved: Building mobile apps that solve real problems
Your phone is always with you - but your interview prep wasn't.
I worked with analysts and associates from bulge brackets and elite boutiques - many of them former classmates now thriving in IB and PE - to ensure every question and answer reflects what's actually being asked in interviews today, not five years ago.
And the app was only the beginning. IB Interview Questions has since grown into a full practice platform on the web: 1,900+ technical and behavioral questions with model answers, interview-ready guides that make you conversant in a whole sector, brainteasers, and progress tracking that follows you from your phone to your browser.
Making Elite Prep Accessible
Our belief is simple:
- Great interview prep shouldn't cost $500/hour
- You should be able to practice anywhere, anytime
- AI can give you better feedback than most humans
- Consistent daily practice beats weekend cramming every time
Since launching, we've helped 3,000+ students prepare smarter, not harder. They're landing offers at every major bank and PE fund, from every type of school.
