Want to start a strategic career in the data area? Check out the tips of the DNC School

THE DNC School, the main edtech responsible for transforming careers with practical education, sees a great opportunity for those who want to join or migrate to the technology and information analysis sector. The area continues to expand in 2025, driven by the growing need for companies to use analytical intelligence to guide strategies, automate processes and customize services. To have an idea, the global market for analysis and artificial intelligence should exceed US$ 500 billion by the end of the year, according to the International Data Corporation (IDC).

In Brazil, the accelerated digitalization and growth of e-commerce have expanded the search for professionals capable of interpreting large volumes of information and generating strategic insights. Businesses in the financial, health and retail sectors are directing investments towards these solutions, seeking to improve the customer experience, anticipate trends and optimize operations. As a reflection of this movement, the demand for data scientists and machine learning engineers has skyrocketed, with salaries for senior positions that can exceed R$ 20 thousand.

According to a recent survey by edtech itself, this movement was proven with a ranking of the most sought-after training to help professionals reposition themselves in the market. The list brings the courses with the highest number of enrollments in the institution, based on the 23 available topics. Business Intelligence Analyst (BI) was the most sought after course (34.5%), followed by Data Scientist (32%) and Data Analyst (26%). 

“The first positions on the list reinforce that “’ are the main professional bets for those looking to change work area in 2025”, says Lucas Rana, CEO and founder of the DNC School.“Technological advancement creates the need for companies to have professionals trained to interpret and organize the large volume of information in the digital universe, driving strategic decisions and revolutionizing” industries, he adds. 

For Barbara Araujo, Engineering Manager of the DNC School, companies seek more than just technical knowledge: a strategic vision and communication skills are needed. “Transforming analysis into concrete actions is a competitive advantage. Companies value professionals who, in addition to interpreting indicators, know how to present results in a clear and impactful manner”, he highlights.

The specialist explains the essential skills to enter the area. “To stand out in the market, professionals in the area must develop both technical skills and behavioral skills.In the technical field, the most valued knowledge includes SQL and data modeling, programming languages such as Python and R, BI tools (Power BI and Tableau) and applied statistics fundamentals”, he comments.

In the behavioral aspect, Barbara says that analytical thinking is essential to question and interpret information strategically. Likewise, effective communication is important to transform them into insights that support business decisions. “Data professionals must convert numbers into narratives that guide business management.The clearer this communication, the greater the impact of the” analysis, says the manager.

Common mistakes of those who are starting out

Beginning professionals often make mistakes that can hinder career advancement. One of the most common mistakes, according to Barbara, is to focus exclusively on the use of tools without understanding the fundamental concepts, such as structuring metrics and statistics. Another critical flaw is to underestimate the importance of communication, since the ability to extract clear and actionable insights is as valuable as technical knowledge.

Failing to build a practical portfolio can also reduce the chances of prominence in the market. “Companies value projects applied to reality. Creating evaluation with public data and publishing them on GitHub or social networks is an efficient strategy to stand out”, says the DNC School expert.

How to stay up-to-date in the industry

With the rapid evolution of AI and data exploration technologies, being up-to-date is essential. Joining expert communities, following influential professionals on LinkedIn, and solving challenges on platforms like Kaggle and DataHackers are ways to continually develop new skills.

For those who want to enter the area, continuous learning and practice are the main allies.“The data sector is expanding and needs professionals who know how to learn, adapt and solve real problems”, concludes Barbara Araujo.
