Terminal
The terminal is the window where a developer types text commands to the computer instead of clicking buttons.
What it tells you about a developer
Terminal comfort is baseline for professional developers. Heavy terminal work, like writing scripts that automate a team’s routine chores, points toward strength in infrastructure and DevOps.
A terminal shows a blinking cursor and waits for typed commands: run the tests, deploy the code, fetch a teammate’s changes. Developers keep one open next to their editor all day, because typing a command is often faster than clicking through menus and far easier to automate. Programs designed to be used this way are called command line tools, or CLIs.
