Interview Practice Evidence

Use this page to decide what to do with a four-hour study block. The short answer: do cold board reps, close them in the IDE, review a little tape, then watch or read exactly the thing your rep exposed. Do not turn video into a second passive curriculum.

For senior technical interviews, bias every rep toward explicit assumptions, constraints, traceability, verification, failure modes, and calm collaboration under interruption. The target is not “I know LeetCode.” The target is “I can make my reasoning inspectable while the problem moves.”

How To Use This Page

The actual daily loop and calendar live in sheet 11. This page explains why that loop is built from cold retrieval, think-aloud practice, observation stress, tape review, interleaving, and short targeted refreshers.

If the day goes badly, do not extend the block. Stop with a clean next rep. Panic training works by repeated recoveries, not by grinding until the nervous system learns that the board is punishment.

The Daily Block

Four to five hours is a ceiling of effortful deliberate practice, not a quota to pad with passive video (Ericsson 1993). Run it as three to four focused sub-blocks with real breaks, and interleave the draws (just study-spaced 3) rather than blocking one topic (Rohrer & Taylor 2007). To run it operably — timed, gated, with drills picked and reps logged for you — use the practice-day skill.

Taking a hint is a positive signal, and a single nervous round is statistically normal even for strong candidates. Talk to keep the process visible, not to sound polished.

What Not To Do

  • Do not watch broad playlists before you have a logged miss.
  • Do not drill one topic for four hours unless the interview is explicitly about that topic. Mixed draws are closer to the real task.
  • Do not optimize for silent speed. Optimize for clarify -> plan -> implement -> trace -> complexity while interrupted.
  • Do not let the public packet absorb employer-specific prep. People, panels, clearance facts, and private sponsor context belong in downstream overlays.
