 ### General technical knowledge
 
-In most cases, organizations need engineers that can work on different areas, instead of focusing on layers or defining fine-grained roles. In those cases, besides relying on the evergreen non-technical skills listed above, you can also rely on the general technical knowledge listed in this section.
