What are the main advantages and disadvantages of the first professional experience gained at the beginning of a career?

Main advantages of first professional experience in C#:

• Gaining practical programming skills and understanding the software development lifecycle.
• Familiarity with the .NET ecosystem and development tools (Visual Studio, NuGet).
• Mastering basic concepts of OOP, working with databases, and asynchronous programming.
• Ability to work in a team and understand software development processes.

Disadvantages:

• Limited experience in solving complex problems and architectural decisions.
• Possible errors due to lack of knowledge and experience.
• Often working with ready-made templates and limited independence.

For example, at the initial stage, one could write simple CRUD applications, which provided an understanding of the basics but did not always allow deep immersion into optimization and scaling.
