Summary

Reddit PM interview with a pretty unusual question that threw me off more than I expected. The whole thing was framed around a biology scenario, which I didn't see coming from a tech company.

Q1

If a vulture's head size doubled, how would that affect its survival and ability to adapt? Walk through your reasoning using root cause analysis.

Suggested Approach

Treat the vulture's head size as a variable in a biological system, then apply root cause analysis to trace how doubling it would cascade through survival and adaptability. Structure your answer by defining the problem, identifying direct and indirect effects, and evaluating trade-offs, while explicitly tying your reasoning to product management principles like systems thinking and hypothesis testing.

Pro tip: Acknowledge the absurdity briefly, then pivot to the underlying skill being tested: breaking down ambiguous problems. Show that you can extract a structured framework from a nonsensical premise, which is exactly what PMs do when facing vague user feedback or market signals.

1. Clarify the premise and define success

Restate the question in your own words and define what 'survival' and 'ability to adapt' mean for a vulture (e.g., finding food, avoiding predators, reproducing). This sets a clear scope and shows you don't jump to solutions.

2. Identify direct consequences of a larger head

List immediate physical and behavioral impacts: increased weight, altered center of gravity, higher energy demands, potential difficulty fitting into carcasses, and changes in sensory organs (eyes, beak) if proportional.

3. Trace second-order effects via root cause analysis

For each direct consequence, ask 'why' repeatedly to uncover deeper implications. For example, a heavier head might lead to neck strain, reducing ability to tear meat, which lowers food intake, affecting energy for flight and reproduction.

4. Evaluate trade-offs and adaptive potential

Weigh benefits (e.g., stronger bite force, better visual acuity if eyes enlarge) against costs (e.g., reduced agility, higher caloric needs). Consider whether the species could adapt behaviorally or evolutionarily over time.

5. Synthesize and conclude

Summarize the net effect on survival and adaptability, acknowledging uncertainty. Relate the exercise to product management: how you'd prioritize hypotheses, test assumptions, and make decisions with incomplete information.

Key Points to Mention

  • Root cause analysis techniques like the '5 Whys' to drill down from symptoms to underlying causes.
  • Systems thinking: recognizing that a change in one part of an organism affects the whole system.
  • Trade-off analysis: balancing potential benefits (e.g., stronger beak) against costs (e.g., increased energy expenditure).
  • Adaptability: considering behavioral, physiological, and evolutionary timescales.
  • Product management relevance: applying structured problem-solving to ambiguous, hypothetical scenarios.
  • Communication: clearly stating assumptions and acknowledging limitations of the analysis.
