SWE Interview Handbook

8-Week Standard Plan

The default full preparation route for a working senior engineer. It balances foundations, repair, artifacts, mocks, target-company adaptation, and rest.

8 weeks Sustainable intensity Senior Engineering Interview Handbook
Start First Chapter Read Companion Chapter

Best for

Full-time engineers who want complete preparation without burning out.

Avoid if

Emergency loops or specialist roles needing a longer foundation rebuild.

Time budget

5-9 focused hours per week plus scheduled mocks and rest.

What this roadmap should produce

  • Reliable preparation cadence that can coexist with work.
  • Delayed retests for weak signals instead of shallow repetition.
  • Story bank, project dossier, company research, and mistake log maintained throughout.
  • Two or more complete loops before target-company simulation.
  • Final week preserves execution quality.
