Where QA candidates lose points in interviews: data on the most common weaknesses

Across 533 scored mock interviews from 277 QA candidates, technical accuracy is almost never the weakest dimension. Candidates lose points on concrete examples and on depth: examples is the lowest-scoring dimension in 44 percent of reports, depth in 41 percent, technical accuracy in 3 percent. The pattern holds in every interview type with enough reports to say.

Testing an LLM feature whose output changes: what 65 eval cases and three runs showed

Six findings from running 65 eval cases through a real LLM interview-scoring prompt three times, with a judge model and consistency sampling, in a public repository anyone can rerun. The model was far more deterministic than the eval budgeted for, the authored expectations were harsher than the prompt, and the judge needed the same context as the system under test.

How the interview readiness diagnostic adapts and scores

This page explains how the free interview readiness diagnostic works: 55 seeded questions across eight QA categories, ten served per session, difficulty adapting after every answer, and a difficulty-weighted score. It publishes no results yet. As of 2026-09-28 the diagnostic has 38 sessions and 24 completed reports, too few to support claims about candidates.
