Thought I had this one but then started second-guessing myself mid-answer.
Start by acknowledging that this is a classic physics question often used to test reasoning and adaptability. Explain the correct mechanism: Earth's axial tilt causes sunlight to strike at a more direct angle and for longer durations in summer, leading to higher temperatures. Avoid the common misconception that distance from the Sun is the primary cause.
Pro tip: Demonstrate intellectual humility by noting that while the axial tilt explanation is correct, the full energy balance involves factors like albedo and atmospheric circulation. This shows you can handle ambiguity and avoid oversimplifying complex systems.
Confirm that the question is about the primary cause of seasonal temperature differences on Earth. This ensures you address the intended scope.
Explain that Earth's 23.5-degree axial tilt causes the Sun's rays to hit at a more direct angle in summer, concentrating energy, and for longer periods, increasing total heat.
Mention that Earth's distance from the Sun varies but is not the main driver; in fact, Earth is closest to the Sun in January (Northern Hemisphere winter).
Relate this to how engineers must consider environmental factors and first principles when solving problems, especially in complex systems like autonomous vehicles.

This is just compound interest so 1000 times 2 to the power of 20, which is about $1 billion.
Clarify the compounding assumption (simple vs. compound interest) and then compute the result using the compound interest formula. For a software engineering role, also connect the calculation to algorithmic thinking, such as exponential growth and its computational implications.
Pro tip: Mention that this is a classic problem illustrating exponential growth, and note that if compounding continuously, the amount approaches $1,000 * e^20 ≈ $485,165,080. This shows you understand both the math and its relevance to algorithms.
Ask whether interest is compounded annually, continuously, or another frequency. This determines the formula to use.
For annual compounding, use A = P(1 + r)^t. For continuous compounding, use A = Pe^(rt).
P = 1000, r = 1 (100%), t = 20. Compute A = 1000 * (2)^20 = 1,048,576,000 for annual compounding.
Explain that this demonstrates exponential growth, which is relevant to algorithm analysis (e.g., O(2^n) time complexity) and financial modeling.
