Compiled languages tend to be faster and catch some errors before the program ever runs, at the cost of a build step and less flexibility. Interpreted languages are quicker to write and test, since you can run code immediately, which suits scripting and rapid development.
The line has blurred: many modern languages use techniques like just-in-time compilation to get speed while staying flexible. For most projects the distinction matters less than the ecosystem and fit, but it explains why systems software leans compiled and quick automation leans interpreted.
