Understanding the Question

When an interviewer asks, "Tell me about a financial model you've built. What was the purpose, and what were the results?" they are seeking to understand several key aspects of your capability as an investment banker. This question is multifaceted; it's not just about whether you can build a financial model, but also about your understanding of its purpose, your analytical skills, and your ability to derive actionable insights from the model. A financial model, in the context of investment banking, could range from valuation models such as Discounted Cash Flows (DCF) and Leveraged Buyout (LBO) models, to merger models and financial forecasts.

Interviewer's Goals

The interviewer is looking to assess:

• Technical Skills: Your proficiency in building complex financial models, which is a fundamental skill in investment banking.
• Analytical Thinking: How you approach problem-solving and whether you can translate business scenarios into financial forecasts.
• Strategic Insight: Your ability to use the model to make or recommend financial decisions, indicating your understanding of the broader business or economic context.
• Communication: Whether you can articulate the process and results of your financial modeling in a clear and concise manner, which is crucial for advising clients and colleagues.
• Attention to Detail: Given the precision required in financial modeling, your answer can also reflect your meticulousness.

How to Approach Your Answer

To effectively answer this question, structure your response to cover the following points:

1. Brief Overview of the Model: Start with a quick summary of the type of model you built (e.g., DCF, LBO, merger model) and its primary objective. This sets the stage for a deeper dive into specifics.

2. Context and Purpose: Explain the situation that necessitated the model. Was it for a valuation of a potential acquisition target, a forecast for a company's financial future, or another purpose? This shows the interviewer the strategic value of your work.

3. Process and Tools: Briefly describe the steps you took to build the model and any specific tools or software you used (e.g., Excel, Python). Highlight any unique approaches or methodologies.

Example Responses Relevant to Investment Banker

Example 1: Valuation Model for M&A

"In my previous role, I built a DCF model to value a potential acquisition target for a client in the healthcare sector. The purpose was to determine a fair price range for the target company to advise our client on their bid. After gathering historical financial data and researching industry trends, I forecasted the company's cash flows for the next ten years and calculated the weighted average cost of capital (WACC) to discount these flows. One challenge was accurately forecasting revenues in a rapidly changing regulatory environment. I conducted a sensitivity analysis around key assumptions, which provided a range of valuations under different scenarios. The model suggested that the target was undervalued, leading our client to proceed with a successful acquisition at a favorable price."

Example 2: Financial Forecasting for an IPO

"For a technology firm planning an IPO, I developed a comprehensive financial forecast model. The aim was to project the company's performance five years post-IPO, covering revenue, expenses, EBITDA, and net income. I used historical performance data, industry benchmarks, and growth projections as inputs. The challenge was predicting the impact of new technologies on future revenue streams. To address this, I built multiple scenarios into the model to capture a range of possible outcomes. The model's results were integral to the IPO prospectus, helping to set investor expectations and contributing to a highly successful public offering."

Tips for Success

• Be Specific: Provide detailed examples without violating confidentiality agreements. Use specific figures and outcomes where possible.
• Show Enthusiasm: Let your passion for financial modeling and investment banking shine through. Enthusiasm can be as compelling as technical skills.
• Practice Your Delivery: Ensure you can discuss complex models in an accessible way. Practicing your response will help you communicate more clearly and confidently.
• Reflect on Learnings: If applicable, discuss what the experience taught you or how it improved your modeling skills. This shows a capacity for growth and self-improvement.

By following these guidelines and preparing thoughtfully, you can turn this question into a strong showcase of your skills and experiences as an investment banker.
