100 Classified Bugs: Severity vs. Priority
A practice set of 100 realistic sample bugs across ten QA areas — authentication, payments, UI/UX, performance, API, database, security, mobile, search, and notifications — each rated for Severity and Priority with a one-line reason for the call. Opens with a plain-English breakdown of what separates the two scales, the Critical/High/Medium/Low and P1–P4 definitions, and a 2x2 matrix of high/low severity vs. priority combinations, including the classic mismatches that trip people up in interviews.
Severity vs. priority is a QA fundamental that somehow still trips people up in interviews, because the textbook definition and the real judgment call aren't quite the same thing. I built the 100 sample bugs around realistic scenarios specifically so you'd have to make the call yourself before checking the reasoning — that's a different skill than memorising the 2x2 matrix. Worth doing even if you think you already know the difference; the classic mismatches near the end catch most people.
