ACROSS EVERY PATH

Four habits that matter more than the roadmap

01

Build, don't just read

Every milestone above is a project. A small working design teaches more than a week of videos.

02

Publish your work

Put projects on GitHub with a clear README. Interviewers open these links.

03

Explain it out loud

After each stage, explain the topic to someone else, or record yourself. Gaps show up immediately.

04

Practise interviews early

Take the quiz monthly, and do a mock interview before the real ones.
