The importance of a well-made CV

Your resume is more than a document: it's a personal positioning tool.

In Mexico, each job posting receives between 200 and 400 applications, according to data from LinkedIn 2024and only a small percentage move on to the interview phase.

In that context, avoiding the common mistakes when writing a CV It becomes an act of professional strategy.

An up-to-date and accurate resume conveys order, responsibility, and attention to detail.

If you can reflect that from the first line, the recruiter will see you as someone who knows how to communicate their value.

Have you ever wondered how many opportunities you might have missed because of a simple typo or an unclear structure?

That's a question many professionals only ask themselves when it's too late.

Common mistakes you should avoid

The first step to improving your CV is knowing what NOT to do.

Among the common mistakes when writing a CVThe most common ones in 2025 are the following:

Excessive irrelevant information

Adding every job you've had, regardless of its relation to the position, can reduce clarity.

A recruiter looks for consistency, not volume.

It is preferable to highlight three or four relevant experiences with measurable achievements rather than filling pages with redundant information.

Do not tailor your CV to each job offer

Using the same document for all positions is one of the most serious mistakes.

Tailoring your resume to the job profile demonstrates interest and understanding of the role.

Lack of quantifiable data

Recruiters trust numbers. “I increased sales by 20%” sounds more convincing than “I improved the department's results.”

Poor writing or spelling mistakes

Nothing generates more distrust than a resume with basic errors.

In 2025, where attention to detail is key, a single mistake can detract from professionalism.

Ignoring the visual structure

Design has more influence than you might imagine.

A resume that is cluttered or has illegible fonts may be discarded without even being read.

Language, format and content: the perfect balance

Writing a good resume involves mastering three elements: clarity, relevance, and authenticity.

Clarity: Use short sentences, avoid unnecessary technical terms, and organize the information into blocks.

Relevance: Highlight the achievements most aligned with the position.

Authenticity: Don't exaggerate your skills; recruiters can easily spot inconsistencies.

Practical analogy

Your CV should be like a professional elevatorIn less than 30 seconds, your profile should be uploaded and leave a positive impression.

If it takes too long or stops on each floor (irrelevant detail), the recruiter simply gets off before reaching the end.

How recruiters will evaluate your CV in 2025

Modern companies use systems of Applicant Tracking System (ATS) to filter resumes.

These systems search for specific keywords before the document reaches a human.

Therefore, if you fall into the common mistakes when writing a CVYou could be left out even before being read.

Recommendations:

Use terminology related to your industry.

Avoid inserting graphics, tables, or decorative icons that the system cannot read.

Save the file as a PDF or Word document to maintain the original formatting.

Update your LinkedIn profile with the same information; recruiters often compare both.

Real-world examples and practical recommendations

Original example 1:
Poorly worded: “Responsible for coordinating projects and teams in the marketing area.”
Winning version:

“I coordinated a team of 10 people on digital campaigns that increased web traffic by 45.% during the first quarter.”

Original example 2:
Poorly worded: “Customer service and technical support.”

Winning version: “I provided technical support to more than 100 users weekly, reducing the average response time by 30 %.”

These examples reflect how a vague description can be transformed into an impactful statement of achievements.

Technical errors versus strategic errors

Not all mistakes carry the same weight. Some are technical (related to formatting or grammar), while others are strategic (related to focus or message).

Look at this table to differentiate them and learn how to correct them:

Type of error	Description	Impact on your profile	How to avoid it
Technical	Spelling, formatting, typography	Half	Review using tools and human reading.
Structural	Disorganized sections or excessive text	High	Use modern templates and check for consistency
Strategic	Lack of personalization or specific data	Very high	Tailor your CV to each job offer with metrics
Visual	Colors or fonts that are difficult to read	Half	Keep the design clean and professional.

An impeccable resume is not the most decorated, but the one most consistent with your purpose.
