Every number here is counted from the library itself, not estimated.
Most prep is reading. This is a loop: learn the piece, prove it under scoring, get told plainly what is weak, then work the exact fix.
No card. The first win here is a scored one, and everything in this section is free in full.
Drills and data problems grade on submission; the starter case is scored against a rubric.

What consulting firms and finance teams actually do all day, how the work is staffed, and how hiring decisions get made. Start here if the words strategy and coverage still feel vague.
Free
Two calendars run this process, one for consulting and one for finance, and they do not move together. This level puts your class year on both and sets a target list you can actually finish.
Paid
Your resume gets seconds before a person decides. This level rebuilds it line by line for the screen it will actually face, and covers the cover letter for the firms that still read one.
Paid
Cold outreach fails when it asks for too much and says too little. This level gives you a working system: who to contact, what to write, and how to run the call once someone answers.
Paid
Case math is arithmetic under pressure, done out loud, with no calculator. This level builds the speed and the narration habit together. The first briefing in this level is free.
Paid
Interviewers can hear a memorized framework in ten seconds. This level teaches you to build a structure from the question itself, so it fits the case in front of you.
Paid
Fit questions decide more interviews than candidates expect. This level builds a story bank from your own experience and teaches you to deliver each story with its point intact.
Paid
The final round is a different test from the first. This level covers first rounds, second rounds, and final rounds separately, including partner level conversations and what changes when the interviewer stops leading.
Paid
Competitive consulting and finance clubs are a recruiting channel of their own, with their own applications and interviews. This playbook covers choosing clubs, applying, and interviewing for a seat.
Paid
Banking and finance interviews test technical knowledge directly. This wing covers accounting, valuation, and the market questions, at the depth an interview actually reaches.
Paid
Banking interviews test accounting the way case interviews test structure: directly, and at working depth. This track inside the Finance Wing builds the three statements as one system, drills transaction effects until they are reflexes, and then builds free cash flow, LBO mechanics, and modeling on top of them. The first briefing in this track is free.
Paid
Full time recruiting runs on a faster clock and a thinner margin for error. This track covers MBB full time, Big Four full time, finance rotation programs, big tech finance, and investment banking full time.
Paid
Markets seats test a different candidate from banking: live market judgment, fast arithmetic, and composure when a price moves. This track covers the desks, the shared banking calendar, the recorded screen and the superday, and the pitch, with a market math drill in Practice.
Paid
Private equity hires mainly from banking and consulting analyst seats, through a process run by search firms that publishes almost nothing. This track covers the business, the on cycle and off cycle reality, the modeling test, the paper LBO, and investment judgment, labeled as general guidance wherever firms publish nothing.
Paid
Trading firms and quant funds screen on probability, expected value, games, and mental math, with no finance knowledge required and no case interview anywhere. This track covers the landscape, the assessment driven process, the core skills at working depth, an honest fit test for business majors, and a dedicated Green Book section that teaches Heard on the Street's question families through original questions.
Paid
The data skills analysts actually use: Excel, SQL, Python, charts, statistics, and AI tools, each taught on business examples and backed by graded problems.
These are the standard references candidates already know. This product covers the ground they cover and turns it into live practice, with drills that grade on submission, cases scored against a rubric, and a companion who runs the work with you.

I am Richard, your interviewer here. I run cases with you, drill your math, and tell you plainly which part of your game needs work. Ask me something, or press Hear it and I will introduce myself out loud in your device voice. The studio voice connects at launch.
