An interactive, spaced-repetition trainer for investment banking technical interviews — built around M&A, valuation, and accounting fluency. No LBO/PE content by design (that ground is covered elsewhere); this trainer goes deep specifically where most candidates are shallow: accretion/dilution mechanics, purchase price allocation, three-statement flows, and DCF sensitivity.

- Merger Model Cockpit — live sliders for premium, financing mix, and synergies driving a real-time EPS bridge and accretion/dilution gauge, with callouts that flag value-destroying accretion the moment it appears
- Purchase Price Allocator — drag write-ups and watch goodwill and the deferred tax liability move together, exactly as they do on a real balance sheet
- Three-Statement Flow — ten scripted transactions (depreciation, deferred revenue, PIK interest, asset sales, goodwill impairment...) animated line-by-line across the income statement, cash flow statement, and balance sheet
- DCF Anatomy — WACC/growth sensitivity as a live heatmap, with the terminal-value share of enterprise value flagged in red past 80%
- Exchange-Ratio See-Saw — a literal balance beam for merger-of-equals contribution analysis
- Generative math drills — accretion/dilution calls, goodwill creation, exchange ratios, and premium math, all randomized so answers can't be memorized
- Interviewer chain trees — 22 trees of real follow-up questions mined from Wall Street Prep's Red Book, McKinsey/BCG-style cross-examination on M&A, valuation, and accounting
- Spaced repetition — a Leitner-system review queue tracks every drill and chain node, scheduling weak spots back sooner
