## What it does

The skill walks you through four steps: define the core of the role, build practical assessments, apply a standardized rubric, and run reference checks. It carries principles drawn from Lenny's Podcast and Newsletter, sourced from 27 guests. Brian Halligan suggests asking a reference whether the candidate ranked in the top 1 percent of employees and whether they would enthusiastically rehire them. Kevin Yien sends an email at the offer stage listing the company's worst problems — anyone who reads it and stays excited is a strong hire.

The skill asks you questions: what outcomes the new person must hit in the first six months, whether you use one rubric across interviewers, which real roadmap problem could serve as a work trial. It also flags common mistakes — over-weighting interview polish, hiring for domain experience instead of first-principles thinking, treating reference checks as a formality, leaning on hypothetical case studies.

Nothing beyond the skill file is required — no API keys, no external services. Install runs through `npx skills add`, and the file lands at `~/.claude/skills/interviewing-evaluating-candidates/SKILL.md`. The skill does not replace your rubric or store candidate data; it works as a playbook inside the conversation with your agent.

npx skills add RefoundAI/lenny-skills --skill interviewing-evaluating-candidates -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/RefoundAI/lenny-skills/tree/HEAD/skills/interviewing-evaluating-candidates/SKILL.md

## When to use it
- pin down which skills to test for a specific role
- swap abstract case studies for a work trial from your real roadmap
- get interviewers onto one shared rubric
- verify a candidate through references instead of interviews alone
- filter out people who interview well but execute poorly

## Example prompts
- help me build an evaluation rubric for a product manager role
- what should I ask a reference to learn the candidate's real contribution
- suggest a work trial project based on our roadmap for this role

# Interviewing and Evaluating Candidates

Move beyond resumes to assess high-fidelity signals like agency, first-principles thinking, and actual craft.

Help the user with interviewing and evaluating candidates using insights from 27 guests and posts across Lenny's Podcast and Newsletter.

## How to Help

1. **Define the Role Core** - Identify specific competencies and core jobs the candidate must perform based on your unique organizational needs.
2. **Design Practical Assessments** - Move from abstract case studies to almost-real-life assignments or paid work trials that mimic the actual job.
3. **Apply Standardized Evaluation** - Implement consistent rubrics and thematic questioning to reduce bias and increase signal quality.
4. **Conduct High-Fidelity Reference Checks** - Verify performance with past collaborators to triangulate interview signals and uncover long-term patterns.

## Core Principles

### Prioritize Enthusiastic Rehires
Brian Halligan: "I think CEOs and everyone dramatically overrates their ability to interview, and overrates their gut feeling, and underrates a really high quality blind reference."

The most effective hiring signal is asking a reference if the candidate was in the top 1 percent of employees and if they would enthusiastically rehire them.

### Use the Unsell Email
Kevin Yien: "When you get to offer stage, I send an email and I say all the terrible things that are probably going to reinforce their fears. If you can tell them that upfront and they can read that whole email and still be equally excited to join you, find yourself a A+ hire."

Send an email at the offer stage detailing your company's biggest flaws and challenges to ensure the candidate's commitment is based on reality.
