Liminal
No one is born thinking in structures. The candidates who walk out of MBB interviews with offers learned it — deliberately, systematically, one skill at a time. Liminal is how you learn it.
Chapters I & II free forever · No card needed
You memorize profitability frameworks. You practice with friends who tell you “that was good.” You read PDFs written for interviews that happened a decade ago.
None of it builds the actual skill — the ability to look at any problem, structure it cleanly from first principles, and think your way to an insight in real time.
That's what interviewers are actually testing. And it's entirely learnable.
A structured curriculum that starts from zero and builds upward — MECE thinking, issue trees, hypothesis testing, estimation, analysis. Each skill unlocked in sequence, each concept immediately drilled, each answer scored against the same rubric a consulting partner would use.
Not a question bank
An idea arrives as a lesson, gets drilled into reflex by short reps, then tested cold. Chapters close with a full case — real exhibits, worked one step at a time, each step revealed before the next. Nothing is random.
Not a scorecard
Every answer is graded against an authored model answer on a published rubric, and the feedback quotes your own sentences back to you. It also remembers: the weakness you keep repeating gets named, and you get sent straight to the lesson that fixes it.
Not a framework library
Frameworks are crutches. Liminal teaches you to build structures from first principles — so you can handle any case, not just the ones you've seen before.
Chapter I — Foundations
ILesson, reps, drill, full case. In that order.

74Your cut holds. You named the lens before you branched, and cost-per-unit × units spans the whole problem — that's the hard part, and it's done. The slip is the move after it. You dug into contract manufacturing because it was ‘the largest cost line, so that's where the margin went’ — but size isn't movement. A line can be 60% of the cost base and perfectly flat. You're hunting the line that changed.
Then you shut the others down — ‘so this is a cost problem, not a revenue one’ — before anything ruled out price erosion. Pick on impact × likelihood, say the reason out loud, and park the branches you didn't take instead of killing them.
It reads your reasoning, not your keywords.
