OpenAI SWE Loop

This course contains a growing collection of previously asked OpenAI SWE past coding questions. OpenAI interviews are known to repeat problem patterns at a relatively high frequency, so practicing these questions can significantly improve both speed and confidence during the real interview.

Work through realistic problems such as GPU Credit Calculator, Time-Based Key-Value Store, Monster Teams Battle Simulator, Spreadsheet with Cells, and more. Each problem is selected to reflect the style, difficulty, and reasoning depth expected in the OpenAI coding loop.
