Field Cards

How to use this resource

Print or keep these cards beside you during practice. Do not read them during a live interview unless notes are allowed.

Print this page and cut at the card boundaries, or keep it open during solo practice. Each card is a retrieval cue, not a script. Cover the lower lines, recall the sequence aloud, then reveal the card and check what you missed.

Card 1 — Response loop

Recall: Clarify → model → plan → execute → validate → reflect.

Use when: A prompt feels large or you start moving without a visible structure.

Self-check: Did each transition produce evidence, or did you merely announce a phase?

Card 2 — Senior evidence

Recall: Scope, judgment, trade-offs, production ownership, delivery impact, influence, reflection.

Use when: Reviewing whether an answer demonstrates senior work rather than task completion.

Self-check: Which claim could another person verify from the answer?

Card 3 — Coding invariant

Recall: State, invariant, movement rule, boundary, complexity, adversarial test.

Use when: You recognize a pattern but have not yet proved it fits.

Self-check: What remains true after every iteration, and which input would break that claim?

Card 4 — Design checkpoint

Recall: Users, critical flows, APIs, owner of truth, scale, failure, observability, security, cost, evolution.

Use when: A diagram is collecting boxes faster than decisions.

Self-check: Can you trace one important write and one important read through failure?

Card 5 — Project evidence

Recall: Context, stakes, constraint, personal decision, alternative, rollout, result, influence, lesson.

Use when: A project story sounds like a team summary or expanded résumé bullet.

Self-check: What did you decide, why was it difficult, and what changed because of it?

Card 6 — Recovery

Recall: Name the mismatch → preserve useful work → revise the assumption → test the new path.

Useful line: “That result conflicts with my assumption. I’ll keep the model that still holds, revise this boundary, and test the simpler path first.”

Self-check: Did the recovery become more evidence-driven, or merely more confident?

Practice protocol

Shuffle the cards. Draw one before a drill and one afterward. The first card sets the behavior to expose; the second tests whether the evidence was visible. Retire a card only after the behavior appears in two delayed, interview-shaped attempts.
