5 Common Resume Mistakes and How to Fix Them!

🎯 “When I landed my first full-time job offers, it wasn’t luck—it was learning from my mistakes.” – Jeff Comfort

Hello, friends! My name is Jeff Comfort, and today, I want to walk you through one of the most pivotal learning curves in my career: fixing a bad resume. 🚀 Back when I was just starting out, it wasn’t pretty. I sent out 367 cold emails, landed 21 first-round interviews, and secured five full-time offers. Most of those breakthroughs came only after networking heavily and massively upgrading my resume thanks to feedback from recruiters and hiring managers.

In this blog, I’m breaking down the top five rookie resume mistakes that almost cost me opportunities, along with actionable tips to help you stand out. Whether you’re a student applying for your first role or a seasoned professional polishing up, I’ve got you covered. Let’s dive in! 💼✨

Mistake #1: Wrong Resume Structure

The Problem

I’m not going to sugarcoat it—my early resume was a trainwreck. The education section came first, which I thought was “logical” because I was proud of my GPA, SAT scores, and academic achievements. However, recruiters don’t have 30 seconds to skim fluff! They care about relevant work experience.

Let’s Compare:

• Bad Resume: GPA displayed prominently at the top with class lists, and high school laurels (yikes).
• Better Resume: Work experience featured first—whether it’s an internship, a part-time job, or related extracurricular projects.

The Fix

Start your resume with a Professional Summary (if applicable), then Work Experience. This layout gives recruiters immediate context about whether you can solve the challenges they’re hiring for.

Pro Tip:

Even if your experience is limited, detail how internships or side projects taught you transferable skills. Showcase technical tools like Excel or problem-solving instances like managing club budgets.

Mistake #2: Not Showing Impact

The Problem

Take this bullet point from an old version of my resume:
“Assisted with project governance, presented to a banking client, and helped with project research.”

Sounds okay, right? Wrong. It’s vague, buzzword-heavy, and gives no clear idea of what I actually achieved.

Compare With This Updated Version:
“Delivered governance process improvements, resulting in a 25% faster approval pipeline for banking client expansion in the local market.”

Why It Works:

1. The results (“25% faster pipeline”) make my contribution concrete.
2. It connects my actions with tangible business outcomes.
3. It tells a recruiter: “This person’s work drives impact.”

Action Step:

Frame your contributions in terms of outcome, not activity. Use this formula for every resume bullet:
[Action Verb] → [Task] → [Result/Impact]

🔑 Example: “Coordinated social media marketing campaigns for a nonprofit, raising engagement by 47% over a 6-month period.”

Mistake #3: No Metrics? No Problem

The Problem

I hear this question all the time: “Jeff, how do I quantify work when I don’t have fancy stats to show off?” 😰

Quite frankly, I’ve been there. Not every role has measurable KPIs, especially when you’re in school or working in a startup. But metrics matter because they show effort, context, and performance standards relative to the job market.

The Fix

Find creative ways to measure effort and benchmarks. Examples:	Role/Task	Quantified Result
Tutor SAT Preparation	“Improved average student SAT scores by 280 points across eight students.”
Admin Assistant	“Delivered 100% accurate meeting agendas for 25+ stakeholders weekly.”
Internship “Coffee Runs”	“Delivered nine coffee orders daily with 100% accuracy over three months.”

Formula for Metrics:

1. Action: What did you do?
2. Scale: How many/much?
3. Results: What happened because of your action?

Mistake #4: Your Resume Isn’t a Template—It Needs to Be Tailored

The Problem

Applying for dozens of jobs meant I didn’t customize my resume early on. I figured one generic format could fit every role. Spoiler: It doesn’t.

Recruiters skim resumes for the exact skills and tools mentioned in their job descriptions. Miss those keywords, and you might not even clear the ATS (Applicant Tracking System).

The Fix

Copy/paste the job description into a keyword generator and identify core skills. Then tweak your resume to include them in context. Here’s an example:

Job Posting: “Seeking someone proficient in data analysis and forecasting models.”
Your Resume Update: “Developed forecasting models using data visualization tools (e.g., Google Sheets, Tableau).”

Pro Tip:

If creating multiple resumes feels overwhelming, focus on tailoring 3-5 “core resumes” for similar job roles. For example:

1. Marketing Analyst Resume
2. Data Scientist Resume
3. Entry-Level Finance Resume

Mistake #5: Neglecting the Little Things

The Problem

Small details like inconsistent formatting (e.g., mismatched hyphens or fonts) or overlooked typos can cost you the interview.

Imagine This:

A hiring manager notices, “Why are some positions bolded but others aren’t? Why does this sentence randomly skip punctuation?” . . . Guess what? Low-effort resumes = low-effort candidates in their eyes.

The Fix

Run your resume through Grammarly or Google Docs for spelling/grammar corrections. Better yet, ask 3-5 people in your network to review it.
