Rules that apply to every track
- One track at a time. Two half-finished paths read as neither on a CV.
- Ship in public. A deployed project beats a certificate in every one of these interviews.
- Measure everything you claim — "faster" and "better" need a number beside them.
- Re-read the job ads at every stage. Match your stack and project wording to what the role actually asks for.
- Six focused hours a week finishes a track. Twenty hours one weekend a month does not.
- Never pay for placement. Every tool here has a free tier or a local equivalent.
