Okay — tactical map: • Google: Focus on Interview Flow PDFs, PDF4 (Systems Design Playbook), and Linux Internals PDF. Practice SLO contracts and NALSD deep dives. • Meta: Focus on Troubleshooting Handbook (PDF6) + Linux Internals (eBPF, pprof, kernel sched). Practice live debugging scripts. • Both: Keep the Coding PDFs (Python + Go practice) daily for automation tasks; use the Behavioral Vault (PDF 7) weekly for STAR(M) rehearsals.
