How to create a resume for a tech company: a complete guide

In the tech market, competition for talent is fierce, but the gateway to the best opportunities remains the same: your resume. However, many qualified professionals fail before even speaking to a recruiter. The reason? An inefficient organization that ignores how tech companies actually evaluate candidates.

To demystify this process, Pedro Arbex's People team Skyone, shared valuable insights in Recruta Talks on how to structure a resume that is not only read, but also secures your spot in the next stage of the selection process.

In this article, we will break down the mistakes that make resumes "invisible" and provide a step-by-step guide to building a strategic document.

The invisible enemy: understanding the ATS system

Most technology companies use applicant management systems known as ATS (Applicant Tracking System). When you click "apply" on LinkedIn, your resume is processed by these software programs.

The big problem is that resumes that look visually appealing to humans can be illegible to machines. If the system can't extract your information correctly, you're automatically discarded.

3 fatal formatting errors you should avoid:

Using columns: ATS systems read from top to bottom and bottom to top. Resumes divided into columns (left and right) confuse the software, mixing sections and making the data useless for filtering. Organize your CV as a continuous text document.
Information in images or graphs: never place important data within images. The ATS only reads plain text. Bar charts to measure "competency level" are invisible to the system and add no real value.
Inappropriate file format: always save as PDF. Unlike Word (.doc), PDF preserves the original formatting and ensures that the recruiter will see exactly what you intended.

The ideal structure: a step-by-step guide to success

For technology companies, "less is more." The goal is to be objective, clear, and strategic. Check out the recommended structure:

1. Clean header

Keep only the essentials: full name, phone number, email, and location (city/state). There's no need to include marital status, number of children, or full address with street and zip code; this information is not relevant for the initial screening.

2. Strategic Professional Summary

Forget generic phrases like "seeking new challenges." Your summary should synthesize who you are and what results you deliver.

Weak example: "Professional with 5 years of experience in Python seeking opportunity".
Strong example: “Python developer with 5 years of experience in high-availability systems. AWS specialist with a track record of reducing product latency, serving over 1 million active users.”

3. Experience focused on results

This is the heart of your resume. Instead of simply listing responsibilities (which seem like a copy of the job description), specify what you accomplished.

Use the logic: action + scale + result.

Instead of: “Experience with REST APIs”.
Use: “I developed REST APIs that reduced system integration time by 20%, generating a positive impact on daily operations.”

4. Management of technology stacks

For development and product roles, the tools and languages (stacks) should be presented clearly and sequentially. Create a specific section for technical skills.

Golden tip: standardize the spelling of terms. If you use "Node.js", write it exactly like that throughout the document. Variations such as "Nodejs", "node js" or "NODE.JS" can make it difficult to filter by keywords.

The final checklist before sending

Before uploading your CV for your next tech job, review these essential points:

[ ] Is the file in PDF format?
[ ] Is the file name professional? Rename it to YourName_Surname_Resume.pdf. Avoid names like final_version_3.
[ ] Were the gaps explained? If you took a gap year or did an exchange program, put that on your resume to avoid confusion about periods away from the job market.
[ ] LinkedIn profile up-to-date? Your resume and your social media profile should mirror each other. Conflicting information breeds distrust.

In conclusion: your resume is your ticket

A well-crafted resume doesn't guarantee a job, but it's the necessary entry point to the process and get called for an interview with HR. Invest time in making it robust and strategically formatted for the tech world.
