Exercise 0.A - The readiness map
Take the posting you fixed as your target role and produce a readiness map against it.
List every requirement in the posting, not the ones you remember. Most postings carry between eight and twenty once you separate compound sentences, and the ones buried in the responsibilities section count.
Against each requirement, record four fields. The category: ready now, transferable, or needs development. The evidence: what specifically you did, with a date and a context. The checker: who could confirm this, or which document shows it. And for transferable entries only, the difference: what is not the same about the target context.
Two rules make the difference between an instrument and a self-description. Every ready-now entry must name a checker, because Mabe and West's strongest moderator is the expectation that a self-rating will be tested against something objective. And every transferable entry must name the difference, because a transfer claim that cannot say what is not the same is a hope.
Takes about two hours. It fails in one specific way: a map with an empty needs-development column. If yours comes back empty there, either the posting is below your level, which is a finding worth acting on, or you stopped reading the posting at the point where it became uncomfortable.
