Investment banking technical interviews test whether you understand finance—but more importantly, they test whether you understand it in the right order. Learning DCF models before you know how the three financial statements connect is like learning calculus before algebra.
Why Learning Order Matters More Than Study Time
Most candidates fail not because they didn't study enough—they fail because they studied in the wrong sequence. They jump to DCF models without understanding accounting, then panic when asked "Walk me through how depreciation flows through the three statements."
Investment banking technicals are hierarchical. Each concept builds on the previous one.
The Five-Level Hierarchy
Level 1: Accounting Fundamentals (Week 1-2)
This is your foundation. Every technical question traces back to the three financial statements.
What You Must Master:
The income statement flows into both the balance sheet (through retained earnings) and the cash flow statement (through net income). Changes in balance sheet accounts explain the adjustments on the cash flow statement.
Common Questions: - "Walk me through the three financial statements and how they're linked" - "If depreciation increases by $10, walk me through the impact on all three statements"
Time Investment: 7-10 days until you can answer these in your sleep.
Level 2: Enterprise Value vs. Equity Value (Week 2-3)
Enterprise Value = Value of entire business operations = Equity Value + Net Debt + Preferred + Minority Interest - Non-Operating Assets
Equity Value = Value to common shareholders = Share Price × Fully Diluted Shares
Time Investment: 5-7 days. This concept is straightforward but critical.
Level 3: Valuation Methodologies (Week 3-5)
The three core methods:
- Comparable Company Analysis (Trading Comps): Value based on public peer multiples
- Precedent Transaction Analysis: Value based on past M&A deal multiples (includes control premium)
- DCF Analysis: Value based on present value of future cash flows
The Five Steps of a DCF: 1. Project unlevered free cash flows (5-10 years) 2. Calculate WACC 3. Calculate terminal value 4. Discount everything to present value 5. Convert enterprise value to equity value
Time Investment: 10-14 days. DCF is the most tested methodology.
Level 4: Merger Models (Week 5-6)
M&A models determine whether an acquisition increases or decreases the acquirer's EPS (accretive vs. dilutive).
Quick Rule: If acquirer's P/E > target's implied P/E, deal is likely accretive.
Time Investment: 7-10 days.
Level 5: LBO Models (Week 6-7)
LBO models calculate PE returns from acquiring a company with debt, operating it for 5-7 years, and selling.
Paper LBO Mental Math: - Rule of 72: If equity doubles, IRR ≈ 72 / years - Rule of 114: If equity triples, IRR ≈ 114 / years - Rule of 144: If equity quadruples, IRR ≈ 144 / years
Time Investment: 7-10 days.
The 6-Week Study Plan
Weeks 1-2: Accounting + EV/Equity Value Weeks 3-5: Valuation methodologies (focus on DCF) Week 5-6: M&A models Week 6-7: LBO models
