Q1. Walk me through a Discounted Cash Flow (DCF) model.
Why you'll be asked this: This question assesses your fundamental understanding of valuation methodologies, your ability to structure a complex financial model, and your grasp of key drivers like free cash flow and the cost of capital. Interviewers want to see if you can explain the mechanics clearly and logically.
Start by defining a DCF as a valuation method that estimates the value of an investment based on its future cash flows. Outline the steps: 1) Project Free Cash Flow to Firm (FCFF) for a discrete period (e.g., 5-10 years), detailing revenue growth, margins, D&A, CapEx, and NWC changes. 2) Calculate the Terminal Value using either the Gordon Growth Model or the Exit Multiple Method. 3) Discount both the projected FCFFs and the Terminal Value back to the present using the Weighted Average Cost of Capital (WACC). 4) Sum these present values to arrive at the Enterprise Value. Finally, adjust for cash, debt, and other non-operating assets/liabilities to get to Equity Value.
- Simply listing steps without explaining the 'why' behind each.
- Confusing Free Cash Flow to Firm (FCFF) with Free Cash Flow to Equity (FCFE).
- Incorrectly explaining WACC components or how it's calculated.
- Failing to mention key assumptions and their impact (e.g., growth rates, discount rate).
- How do you calculate WACC?
- What are the key assumptions in a DCF, and how sensitive is the valuation to them?
- When would you use the Gordon Growth Model versus the Exit Multiple Method for Terminal Value?
- What are the limitations of a DCF?
