Investment banking interviews are among the most demanding in the financial sector. Here is how to prepare effectively to maximize your chances of success.

The Steps of the Process
The recruitment process in investment banking typically involves three rounds: HR interview to assess your motivation and cultural fit, technical interviews on accounting and finance, and case studies to test your modeling skills. Each step progressively filters out candidates.
Frequent Fit/HR Questions:
- "Why investment banking?"
- "Why our bank specifically?"
- "Walk me through your resume in 2 minutes."
- "What are your strengths and weaknesses?"
- "Where do you see yourself in 5 years?"
Essential Technical Questions:
- The 3 financial statements and their links.
- "Walk me through a DCF."
- "How do you value a company?"
- The difference between Enterprise Value and Market Cap.
- WACC: Definition and calculation.
Technical Questions You Must Master
The 3 Financial Statements: If revenue increases by $10, the Income Statement shows Revenue +$10 but Net Income +$6 (assuming 40% tax). The Balance Sheet shows Cash +$6 and Retained Earnings +$6. The Cash Flow Statement shows Net Income +$6.
DCF Valuation: Project Free Cash Flows for 5-10 years, calculate the terminal value, determine the WACC, discount all flows to the present, sum them to get the Enterprise Value, then subtract Net Debt to get the Equity Value.
LBO: An LBO involves acquiring a company using mostly debt (60-80%). The private equity firm provides 20-40% in equity. The goal is to repay the debt using the company’s cash flows, then sell it in 5-7 years to generate an IRR of 20-25%.

Step 2: Framework (3 min) - Outline your analysis plan: "I will proceed in 3 steps: valuation of the target, analysis of synergies, and then a recommendation."
Step 3: Execution (20-30 min) - Calculate methodically, comment on your actions out loud, and show your reasoning.
Step 4: Recommendation (5 min) - Provide a quantitative summary, a clear recommendation (Go/No-go), and mention risks and limitations.
