Theory Card 105 — Transfer Across Domains / Check
Research lens
Transfer means using a learned principle in a new context rather than only in the exact form it was originally practiced. In the Check stage of BASIC, the goal is to verify correctness, quality, and risk. That makes this concept especially relevant here, because it shapes how much mental work the candidate is trying to carry at once and what gets made explicit.
Why it matters in SWE interviews
This is the difference between memorizing one tree solution and applying the same reasoning to graphs, recursion, or system pipelines. A stage-based framework travels well because the same sequence can guide coding, design, debugging, and project explanation. In practice, Check is where the candidate should ask: Does the answer actually satisfy the prompt, handle edge cases, and survive scrutiny? That question acts like a cognitive boundary. It protects the answer from turning into an unstructured search.
BASIC move
A strong move here is to review and stress-test before you hand the answer over. For Transfer Across Domains, that means deliberately naming the important units instead of juggling them implicitly. The interviewer sees cleaner reasoning, and the candidate benefits from creates a verification loop instead of assuming success.
Common miss
The miss is learning isolated answers instead of a reusable method for building answers. When that happens, the candidate usually feels busy, but the answer is actually becoming less inspectable.
