#ResumeWriting : 8 In 10 Hiring Managers Spot AI Resumes-These 3 Mistakes Give It Away. Guide to How To Write Your Resume Using AI.

/in /by

About eight in 10 hiring managers can spot an AI-written resume, according to a new Resume Genius survey of 1,000 U.S. hiring managers.

Yesterday, I reported that more than two-thirds of hiring decision-makers say that AI resumes are sabotaging the recruitment process by slowing it down, making it difficult for them to verify real skills and experiences.

Now, Resume Genius’ latest study confirms the attitude of employers to AI-generated resumes in greater detail, based on what they’re seeing in job applications right now:

  • Approximately 79% say resumes are more polished and visually appealing than five years ago
  • Around 78% say resumes are better tailored to specific job postings
  • About 76% of hiring managers say the overall quality of resumes has improved in recent years

However, as they note, “better tailored doesn’t always mean more distinctive. AI tools can quickly mirror job descriptions and insert keywords, which helps candidates check the right boxes, but can make applications sound the same.

Among hiring managers:

  • Four in five say they can often tell when a resume has been written by AI
  • An estimated 77% say many resumes appear completely or partially AI-generated
  • A further 69% say resumes are more generic or formulaic than they were five years ago

Additionally, around three in four hiring managers state that:

  • Candidates should disclose AI assistance in application materials
  • AI-written resumes make it harder to understand what a candidate actually did
  • Heavy reliance on AI actually makes candidates seem less skilled

“At the same time,” Resume Genius notes, “some hiring managers view thoughtful AI use positively, but opinions are split.”

About 59% say using AI signals a candidate’s adaptability, while half of all hiring managers say it signals efficiency.

“When hiring managers think a resume was written with AI, it’s usually not one glaring mistake,” they said. “It’s the overall feel. If the tone sounds off or the details feel thin, that’s often enough to raise suspicion. And most hiring managers say they do notice these signals.”

 

Top 3 AI Resume Mistakes To Avoid

The top three AI giveaways to avoid?

  • Unnatural phrasing or tone (51%)
  • Repetitive or overly generic language (44%)
  • Vague or inflated descriptions (41%)

Coming in at fourth and fifth place are buzzword-heavy writing (41%), and, yes, ironically, perfect grammar with no variation (39%).

How To Write Your Resume Using AI

So how can you ensure that your resume passes the AI sniff check?

1. Train ChatGPT On Your Style Of Writing

Use the settings and personalization feature in ChatGPT to train it based on your voice. Some professionals I know upload documents with examples for ChatGPT to be trained on, for instance, LinkedIn posts, blogs, emails, etc. that they wrote entirely without AI, that brought in the most traffic or the most positive responses.

You can create an entire folder in ChatGPT and upload these in the “sources” section of the project folder, to be referenced in connected chats, so that when you’re ready to create documents like a resume or cover letter, these are written as closely as possible to your personal tone and the way you usually write and speak.

2. Check For Redundancies And Be Specific

ChatGPT and other AI tools have a strong tendency to repeat themselves over and over using different phrases that actually mean the same thing. This makes your resume look rushed and unedited, obviously AI, and that you didn’t put sufficient thought into it.

One way to get around this is by cross-checking the output of one LLM against another. For example, you could take the resume ChatGPT created and upload it to Gemini and enter this prompt:

Spot any repetitive language or redundancies in the facts or skills presented in my resume.

You should also be highly specific. Steer away from:

  • Buzzwords and cliches like “dependable team-player”
  • Rambling on and on into paragraphs without being definitive and concise
  • Stating what you did without quantifying impact using metrics and specific details

3. Proof-Read For Honesty

AI-generated resumes will usually appear flattering because AI is biased to almost always make you look and feel good. Ask ChatGPT to tailor your resume to a role, and it will go to great lengths to do so, even fabricating experiences, achievements, skills, and titles that do not exist in your work experience.

So, the best approach is to use ChatGPT either as a:

  • First draft, for a rough outline to see how you’d like your resume formatted and to see what key skills and requirements would be included; afterwards, heavily alter it with your own wording and descriptions and proof-read each section for accuracy.
  • Or, use as a final draft, to grammar-correct, ATS-optimize, and professionally smooth over a resume you’ve already written from scratch.

Either way, always sense-check the final product so that you’re confident you can easily back your claims in an interview. Otherwise, being “AI-savvy” will prove to not be so savvy after all and will backfire.

The whole point is, the hiring process needs to be more humanized–not just from the hiring manager’s side, but also from you, the candidate. If you want to win in your job search and land your target role, you need to lead with human skills.  And the first place you evidence this is in the way you write your resume.
