Financial Viability and Deal Economics Questions

Assess the financial attractiveness of business scenarios and partnership deals by building simplified quantitative models and performing back of the envelope estimates. Key skills include estimating revenue from market size and share, modeling margins and costs, accounting for partnership costs in time and resources, calculating payback period, return on investment, and net present value using reasonable discount rates, and performing scenario analysis for best case base case and worst case outcomes. Candidates should demonstrate comfort with quick mental arithmetic, unit economics, sensitivity analysis, articulating key assumptions, and explaining how financial results inform strategy and decision making under uncertainty.

NPV basics: A project yields $100,000 at the end of each year for 3 years. Use a discount rate of 10% and compute the net present value. If the initial investment is $250,000 paid at time zero, determine whether the project is financially attractive. Show the arithmetic and state assumptions.

Behavioral: Tell me about a time you had to present a rapid back-of-envelope financial estimate to senior leadership to decide whether to pursue a partnership. Describe the situation, the key assumptions you used, how you justified them, the sensitivity you showed, and the final outcome including numeric results if available.

Tornado chart and sensitivity communication: You have a model with 12 input variables affecting NPV. Explain step-by-step how you would create a tornado chart to communicate which assumptions drive NPV most. Describe how you select realistic ranges for each input, how you calculate the impact, and how you would present the chart and interpretation to executives.

Opportunity prioritization: You have two partnership opportunities. Opportunity A: NPV $500k, implementation cost $200k, closes in 3 months. Opportunity B: NPV $400k, implementation cost $50k, closes in 1 month. With limited engineering bandwidth and a focus on near-term cash flow, which would you prioritize and why? Include payback, time-to-cash, and resource constraints in your reasoning.

Data and tools: List the primary data sources, tools, and quick checks you would use to build a 30-minute financial model for a market-entry partnership (e.g., estimating TAM, conversion rates, pricing). For each item, state why it is useful and one limitation to be aware of.
