The “Grind LeetCode” Advice is Mathematically Stupid (I Scraped 1,500 Questions to Prove It)

Grinding random interview problems is mathematically stupid. Companies have massive, hidden biases. Apple tests trees at 4.5x the average. Sprinklr asks 47% Hard questions. Yelp only asks math and logic. Platforms hide this data behind a $35/mo paywall to profit off your anxiety. I scraped 1,500+ recent interview questions across 458 companies to map out exactly what they test. The entire database is free. Look up your interviewer's exact bias before you waste time studying the wrong algorithms.
