Interpreted language
A language executed line by line as it runs. Python, JavaScript, Ruby, and PHP work this way.
What it tells you about a developer
Interpreted-language depth maps to web, data, and product engineering. It carries no seniority reading on its own, so look at what they built with it.
Interpreted languages make writing and changing code fast, because a developer sees the result immediately. That speed is why they dominate web development, automation, and data work. Modern practice adds tooling like TypeScript's type checker to recover the early error-catching that compilation provides.
