OpenAI Data Scientist Interview Questions and Sample Answers
OpenAI’s data scientist interviews are renowned for their depth, covering a blend of advanced probability, resource allocation, system design, and practical engineering. This article delves into some of the most challenging and illustrative questions you may encounter, providing comprehensive explanations, step-by-step solutions, and essential concepts.
A plant disease begins in one cell of an \( N \times N \) grid. Each day, every infected cell infects each of its healthy neighbors (up, down, left, right) with probability \( p \). How many days, on average, will it take for the entire grid to be infected?
This is a classic stochastic infection propagation problem, similar to the SIR (Susceptible-Infected-Recovered) model without recovery. The grid represents the spatial domain, and the infection spreads probabilistically.
