What it means
Prepare for FAANG patterns, not trivia. 93% of questions came from Google, Amazon, Meta, Apple and Microsoft. Their loops reuse a small set of patterns — system design at scale, core data structures, and structured behavioral stories — far more than obscure puzzles.
Most candidates underprepare for Medium. 57% of questions are Medium difficulty — hard enough to fail on nerves, common enough to drill. Easy and Hard each made up roughly a fifth.
Behavioral is one in five — and decisive. 12.5% of questions were behavioral. Candidates who can tell crisp STAR-format stories clear the bar rounds that sink stronger coders.
