Pm Interview Prep

# Create a "Pm Interview Prep" AI Skill

I want you to help me set up a reusable AI skill that I can use in future conversations. Read the complete skill definition below, then help me install it.

## Complete Skill Definition

# 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). The value is the level calibration, the question bank and the prep system; the frameworks (CIRCLES, AARM, STAR, 5-step estimation) are applied through them, with failure modes in `references/framework-deep-dive.md`.

## 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.
- **Switching levels** -- You are an IC PM moving to Senior or Senior moving to Group, and need to understand how the bar shifts.

**When NOT to use:** general career planning (use `pm-career-ladder/`); hiring as an interviewer (this is candidate-side); engineering or design interview prep (this is PM-specific).

## Clarify First

What most shapes this skill's output is the level you are interviewing for and the company running the loop. Settle the inputs below before producing anything. When one is missing or vague and would change the result, ask about it; when it wouldn't, use a sensible default and say which one you used.

- **Target level:** APM, PM, Senior PM and Group PM are scored differently on the same question. The level picks the questions from `references/question-bank.md` and the bar answers are judged against; Senior PM and above are expected to add Reflection to STAR.
- **Company and role:** every company has its own rubric and round mix. A loop heavy on product sense needs CIRCLES practice, a technical-PM screen needs a different plan, and the published guide or recruiter call should set the weighting.
- **Time until the loop:** a week leaves room for the two weakest round types and a few stories. A month allows the full 8-12 story set and 2-3 mocks per round type.
- **Experience to draw on:** behavioral answers are built from real projects with quantified results. Without those, the story worksheet stays empty and answers drift into vague outcomes.

Ask about the two or three inputs that matter most for this request, not the whole list. If the user wants a result straight away, produce it and state your assumptions at the top.

## Quick Start

The workflow, start to finish:

1. Rate yourself across the five round types (`assets/self_assessment.md`); pick your weakest two.
2. Pull level-targeted questions from `references/question-bank.md` and practice solo with the right framework, timed.
3. Run 2-3 mocks per round type using `assets/mock_feedback_form.md`.
4. Refine 8-12 behavioral stories (`assets/story_worksheet.md`) to under 5 minutes each, quantified.
5. Verify that each round type has at least two scored mocks at or above the target-level bar and every story has a number in its result before calling it done.

See `references/round-frameworks-and-prep.md` for the full round reference, framework tables, level-calibration bars, prep workflow, and troubleshooting.

## Anti-Patterns

### Reciting the framework out loud
**Mistake:** The answer opens with "I'll use CIRCLES: Comprehend, Identify, Report..." and then walks through each letter.
**Why it happens:** Prep time goes into memorizing the acronym, so it comes out first under pressure.
**Instead:** Use the framework as hidden structure. The interviewer should feel the structure without hearing the acronym. Record a mock: if you say the framework's name, you are leaning on it too visibly.

### STAR stories with no result
**Mistake:** The behavioral answer spends minutes on Situation, Task and Action, then ends with "it went well and we learned a lot."
**Why it happens:** The action is the part you remember living through, and the numbers were never written down.
**Instead:** State the Result as a number plus a learning in every story. Build the 8-12 stories in `assets/story_worksheet.md` with the quantified result filled in first. That is where interviewers read your level.

### Success metrics with no counter-metric
**Mistake:** "I'd measure success by DAU growth," with nothing on what might break if DAU rises.
**Why it happens:** One clear metric sounds decisive in a timed answer.
**Instead:** Pair every success metric with at least one counter-metric, such as retention or NPS, and say what result would worry you. Interviewers at PM level and above expect it.

## Scope & Limitations

**In scope:** framework-based prep for all five PM round types; level calibration APM-Group PM; question banks and answer templates; behavioral story development and STAR refinement; self-assessment and mock-feedback tools.

**Out of scope:** Director/VP/CPO interviews (executive judgment, board influence, P&L — use leadership coaching); company-specific technical-PM screens (consult the role's rubric); salary negotiation/offer evaluation; resume and outreach prep (use `personal-productivity/resume/`).

**Caveats:** Frameworks are scaffolds, not scripts — interviewers down-rank verbatim recitation; internalize so the structure is invisible. Every company has its own rubric; adjust by the published guide and recruiter call. Mocking with a current PM at the target company beats any book.
