Estimation question

Tesla claims it will make Auto Garage Shops obsolete due to zero maintenance. Estimate how many jobs will be impacted in the US in 5 years and 10 years.

Practice this question out loud. An AI interviewer asks it, follows up like a real interviewer would, and scores your answer. Type or speak.

What this question tests

Multi-step estimation with a debatable causal premise, requiring the candidate to state and defend assumptions about adoption speed.

Clarify scope: jobs tied to routine EV-eliminated maintenance (oil changes, transmission, exhaust), not collision repair, which EVs still need.
Estimate the current US auto-repair workforce, roughly 900K-1M mechanics.
Estimate what share of that work is EV-eliminated maintenance versus work EVs still need, like tires, brakes, collision, software.
Estimate EV fleet share of total US vehicles at 5 and 10 years, say 10% and 30%, using a stated adoption curve.
Multiply job share at risk by EV penetration at each horizon to get jobs impacted.

Distinguishes jobs impacted, some tasks reduced, from jobs eliminated, mechanic fully redundant, since most shops still service brakes and tires.
Uses a stated adoption curve rather than a flat guess, showing the 5-year number is meaningfully smaller than the 10-year one.
Flags that some jobs shift rather than disappear, like EV-specific certification or battery service.

Treating 'zero maintenance' as literal and assuming 100% of mechanic jobs vanish, ignoring tires, brakes, and collision work.
Giving one number for both 5 and 10 years instead of showing how the estimate compounds with adoption.
