 - **Code quality** - How you reason about making sure code is readable and maintainable.
 - **Testing** - How you reason about what to test and how to test it.
 - **Performance** - How you can identify performance bottlenecks and reason around solving them.
 - **System design** - How you reason about concepts like reusability, separation of concerns and various abstractions.
