Describe your professional path and work experience in the commercial sector

This is a personal question, and the answer depends on individual experience. Generally, when describing a professional path, it is worth highlighting:

• Education and initial steps in programming.
• First projects and tasks encountered.
• Technologies and programming languages used.
• Experience working in teams, participation in the development of commercial products.
• Achievements and skills that have been developed.

For example, you can talk about starting with simple projects in C/C++, participating in the development of modules for embedded systems, then moving on to more complex tasks related to code optimization and supporting large projects.
