I got tired of paying $35/mo just to see company-specific tags, so I scraped 1,500+ recent questions across 458 companies to map their actual statistical biases.

I ran some basic frequency math. For example, looking at 100 recent Apple questions, their difficulty is standard (15% hard), but they test BSTs at 4.5x the industry average and backtracking at 2.5x.

The site is completely free, no login required. Just built it to make interview prep slightly less of a black box. Happy to answer any questions on how I scraped/categorized the data.
