Interview prep, the coder000 way

No memorized one-liners. Every question comes with why interviewers ask it, a properly explained answer, a hands-on exercise, the follow-ups to expect, and the red flags to avoid — because an answer you've practiced survives pressure, and one you've memorized doesn't.
