Prepare for the Ethos call

Ethos's AI interviewer asks about your Financial Analyst background. These are our own practice questions for that work, not Ethos's.

What key assumptions do you stress-test first when reviewing a financial model built by someone else?

I focus on revenue growth rate and margin assumptions first, since small changes there tend to have the largest effect on the output, and I check whether the assumptions are grounded in historical data or market comparables versus being arbitrarily chosen. I also verify the formulas are consistent across periods rather than hardcoded in some cells.

How do you approach valuing a company that has volatile or negative near-term earnings?

I lean more heavily on a discounted cash flow approach with normalized long-term assumptions rather than trailing earnings multiples, since near-term volatility distorts multiple-based valuation. I also look at comparable companies with similar business models to sanity check the output rather than relying on a single method.

What's your process for evaluating the risk of a proposed investment beyond just expected return?

I look at the range of outcomes under different scenarios, not just the base case, and consider correlation with other holdings, since an investment can look attractive in isolation but add concentrated risk to a broader portfolio. Downside scenarios matter as much as the upside case for decision-making.

How do you decide which sensitivity variables to include in a financial model's scenario analysis?

I prioritize variables that both have high uncertainty and high impact on the output, rather than testing every input equally. Running sensitivity on a variable that barely moves the result wastes review time and can obscure the assumptions that actually matter to the decision.
