I Built a Resume Reviewer Gem — Here's What It Actually Does

Part of the "My AI Team" Series — Each post covers one specific Gem I use daily. See the full series overview.

I review resumes when hiring for my team. I also occasionally help colleagues update their own CVs when they're exploring new roles. In both cases, I found myself giving the same categories of feedback repeatedly: weak action verbs, missing impact metrics, descriptions of job duties rather than accomplishments. My Resume Reviewer Gem handles that first pass consistently, every time.

What Is a Resume Reviewer Gem?

It's a Gemini assistant configured to review resumes with a focus on structure, impact language, and relevance to a specific role. You paste in a resume — and optionally a job description — and it gives you targeted, actionable feedback rather than generic advice.

Why I Built This Gem

Resume review done well is specific. "Use stronger verbs" is not useful feedback. "Replace 'responsible for network monitoring' with 'monitored network performance across 200+ endpoints, reducing incident response time by 40%' " is useful feedback. Getting to that level of specificity by hand for every resume takes time. The Gem handles the pattern recognition.

  • Hiring: I receive resumes and want a consistent first-pass framework before I read them in detail
  • Helping colleagues: When someone asks me to review their CV, I want to give them substantive feedback quickly
  • My own resume: Kept current even when I'm not actively looking

The Prompt I Use

You are my resume reviewer. You evaluate resumes for structure, impact language, and relevance. When I share a resume: - Flag weak or passive language and suggest stronger alternatives - Identify bullet points that describe duties rather than accomplishments - Note where impact metrics are missing and could be added - Check that the most relevant experience is prominent and easy to find - If I give you a job description, flag gaps between the resume and the role requirements My context: IT and network infrastructure hiring. I value specificity over length. Strong resumes show measurable outcomes, not just responsibilities.

Real Examples — What I Actually Ask It

  • "Here's a resume I received for a network engineer role. What are the top three things this candidate should fix?"
  • "My colleague is applying for a senior infrastructure role. Here's their CV — what experience is undersold?"
  • "Here's a resume and the job posting. Are there obvious gaps that would cause a recruiter to pass on this candidate?"

For the job posting gap analysis, it compared the required skills list against the resume line by line, identified three skills that appeared in the job description but nowhere on the resume, and suggested where in the existing experience they could be surfaced with better phrasing. That analysis took about 90 seconds.

What It's Good At (and Where It Falls Short)

Good at:

  • Identifying passive language and suggesting active alternatives
  • Flagging duty descriptions that should be reframed as accomplishments
  • Comparing a resume against a specific job description
  • Noting where impact metrics could strengthen existing bullets

Where it falls short:

  • It can't verify claimed accomplishments — that's still your judgment call
  • Industry-specific resume conventions vary; it may not know all of them
  • Final hiring decisions involve judgment the Gem doesn't have access to

Try It Yourself — Starter Prompt

You are my resume reviewer. Flag weak language and suggest stronger alternatives. Identify duties-not-accomplishments. Note where impact metrics are missing. If I give you a job description, flag gaps between the resume and the role. My context: [your industry, what you look for in a strong resume, who you're reviewing for]
