Cold 300 → interview-sharp in 6 weeks

You've solved ~300 but they're 9 months cold. This is not more volume — it's the curated high-signal set (NeetCode-150 spine), re-solved by hand to rebuild speed. ~1 hr/day, 5 days/week, in your fresh pre-shift window. Progress saves in this browser.

The method — non-negotiable

Plain editor. No AI, no autocomplete. This is the muscle a live round tests — rebuild it raw.
Timebox 25 min. Stuck? Read the solution, understand it, then re-implement from scratch the same day.
Narrate out loud as you code — simulate someone watching. It's harder, and it's the point.
Spaced redo. Anything you couldn't do clean, redo in 2–3 days. That's what makes it stick.
Track honestly in a sheet: solved-clean? · time · redo-date. The checkbox here means "clean, unaided."

After week 6 — into interview mode

Switch to mixed timed mocks: random problems, 45-min sessions, 2–3/week — no pattern label to tip you off. Add company-tagged sets once you're targeting specific employers. Honest checkpoint: a fresh medium should feel routine. If it doesn't yet, extend reactivation 1–2 weeks before mocks — better than interviewing raw.
