Phase 2 — in progress
Prepare
Everything for the week before an interview, and the hour after a deploy goes wrong.
Interview hub
Questions levelled junior to staff, each with a 30-second answer, a full answer, and the follow-up the interviewer asks next.
Troubleshooting
Symptom-first, not tool-first. Paste the error you actually got and get the diagnostic commands in order.
Quizzes & review
Spaced repetition over what you have read, so it is still there in three months.
Cheat sheets
kubectl, terraform, docker, helm, git — the flags that matter, with real output.
