I Failed My First McKinsey Application
Then I changed how I prepared, reapplied, and got in. Five years later I left the firm to fix the thing that’s broken in case interview preparation.
The Origins of StrategyCase
I prepared for my first consulting application the way almost everyone does. I bought the well-known books, worked through Case in Point, memorized the frameworks, and drilled case after case.
I was rejected.
What I did not understand at the time was where that advice came from. The people writing the most popular case interview resources had largely never worked as consultants, or had last sat in a real interview decades earlier. They were teaching a version of the case interview that no longer existed, and I had followed it faithfully.
So I threw it out and started over. Instead of memorizing structures, I worked on the underlying skills: breaking a problem apart from first principles, forming a view with incomplete information, reading data for what it actually says, and communicating like someone who solves problems for a living rather than someone performing an interview.
I reapplied. That time I got the offer, and I spent the next five years at McKinsey, working on client problems and sitting on the other side of the recruiting process.


Built from My Experience
Inside the firm I finally saw what actually separated a strong performance from a weak one, and how little of it matched what the popular resources taught.
Then I watched my own peers go through it, and I saw the loop.
Roughly 99 out of 100 applicants get rejected. Even among those who reach the interview stage, 90% fail. Yet people keep recommending the same resources that made them fail in the first place.
The doom loop.
That is why nothing changes. An entire industry keeps recycling material that stopped matching reality years ago, and every new cohort of candidates inherits it.
I left McKinsey in 2020 to build the alternative.
Building the Alternative
Everything I have made since starts from the same premise: interviews test skills, so preparation should build skills. Not template recognition, not case volume.
A case method built from the evaluation, not from the textbooks. Structuring from first principles, hypothesis-driven reasoning, data interpretation, and consultant communication, taught in the order they actually develop.
The first dedicated preparation for the McKinsey Solve assessment. When McKinsey introduced the test, nothing existed for it. I built the first resource, and it has been updated continuously since as the games have changed.
Real PEI coaching. The McKinsey Personal Experience Interview was being treated as a generic behavioral round by almost everyone. It is not, and it is scored against specific dimensions.
Firm-specific preparation beyond McKinsey. I expanded to candidate-led case interviews for BCG and Bain, recruitment tests for other firms, fit and behavioral interviews as well as application advice, networking strategies, offer negotiation and career coaching to offer a full end-to-end service for my clients.


What Happened Next
I did not plan for this to become my job. It started alongside consulting work and grew almost entirely through word of mouth.
→ 95% of clients on the full coaching program secure an offer
→ 80%+ of them secure an MBB offer
→ 700+ offers generated for my clients to date
→ 2,200+ coaching sessions delivered
→ 1,600+ five-star reviews across review platforms
Demand outgrew the side project, and coaching became the main work.
In 2025, McKinsey removed me from its alumni network for helping too many candidates get into the firm.

I have scaled back 1:1 coaching to make room for other commitments, so most people now work with me through the courses rather than in sessions.
The free Case Interview Foundations course covers the fundamentals of case and fit interviews at no cost.
The Case Interview Academy is the complete paid program, with the full method plus thousands of practice drills.
Coaching still runs, with a limited number of clients each month.
