FAANG preparation is the disciplined practice of mastering technical interviews at scale-obsessed tech companies (Meta, Apple, Amazon, Netflix, Google). The interview loop includes: technical coding (algorithm implementation), systems design (architecture at scale), behavioral (team fit, leadership), and manager conversation. Most candidates fail not because they can't code, but because they've never practiced the specific formats: write correct code in 45 minutes under time pressure, design YouTube in one sitting without a whiteboard, tell a story about conflict resolution the STAR way.
