27.2 Relying Only on Tutorials

Following tutorials can help with initial learning, but employers may expect the ability to solve new problems independently.

Solution: Rebuild projects without step-by-step instructions, add your own features, and explain your design decisions.

27.3 Ignoring Databases and Testing

Many real applications depend on persistent data and reliable behavior.

Solution: Learn SQL, basic database design, input validation, unit testing, and error handling.

27.4 Weak Project Documentation

Even a useful project can be difficult to evaluate if it lacks setup instructions and an explanation of its purpose.

Solution: Maintain a clear README, document dependencies, provide sample usage, and explain how the project was tested.

27.5 Applying Without Matching the Role

A resume focused on machine learning may not communicate the right skills for a backend development position.

Solution: Create a role-specific resume and highlight the projects and tools most relevant to each application.
