What this skill does
PM Interview Prep Expert Overview PM interviews test five distinct skills, each with its own format, frameworks, and rubric: product sense, execution, strategy, behavioral, and technical. This skill organizes preparation across all five round types and calibrates expectations to the level you are interviewing for (APM, PM, Senior PM, Group PM). It bundles the most-used PM interview frameworks -- Lewis Lin's CIRCLES Method for product design, the AARM Method for improvement/metric questions, STAR for behavioral, and a 5-step estimation framework for market sizing -- plus question banks per round and structured answer templates calibrated by level. Core Capabilities Five round types -- product sense (design), product improvement, strategy, behavioral, technical/analytical, each with format and primary framework Frameworks -- CIRCLES, AARM, STAR (+ Reflection for senior), and 5-step estimation, with worked examples and failure modes Level calibration -- the same question scored differently for APM vs. PM vs. Senior PM vs. Group PM Prep system -- self-assessment, question banks, 8-12 behavioral story development, and structured mock-interview feedback When to Use Preparing for PM interviews -- You have a loop scheduled and need a structured plan to cover all rounds. Mock interview prep -- You are interviewing peers and want consistent rubrics. Self-assessment -- You want to identify your weakest interview category before investing prep time.

Rate yourself across the five round types (assets/selfassessment.md); pick your weakest two. 2. Pull level-targeted questions from references/question-bank.md and practice solo with the right framework, timed. 3. …
