Q1. Walk me through a DCF model. What are its key assumptions and sensitivities?
Why you'll be asked this: This question assesses your foundational understanding of valuation methodologies, your ability to articulate a complex process clearly, and your awareness of the model's limitations and drivers.
Start by defining DCF as valuing a company based on its projected future cash flows, discounted back to present value. Outline the key steps: projecting free cash flows (FCFF or FCFE), calculating the terminal value (Gordon Growth or Exit Multiple), determining the discount rate (WACC), and summing present values. Discuss critical assumptions like revenue growth, margins, CAPEX, working capital, and the discount rate components (cost of equity, cost of debt, beta). Highlight sensitivities such as growth rates, terminal value assumptions, and WACC.
- Inability to clearly articulate each step or the purpose of the model.
- Not mentioning key assumptions or sensitivities.
- Confusing FCFF with FCFE or miscalculating WACC components.
- Over-reliance on memorized steps without demonstrating understanding.
- When would you prefer an LBO model over a DCF?
- How do you typically sensitize your DCF assumptions?
- What are the biggest drawbacks of using a DCF?
