The difference is, in the job interview you’re writing it from scratch yourself. On the job you have to take over from the guy who left 10 years ago and that button was designed in such a way that resizing it will add garbage data to all tables in the database and also send an email to all your customers telling them to switch providers.

The “job” panel is inaccurate. It doesn’t show the twenty-five meetings about the button size, the designer sketches on paper, the UX review, the corporate stakeholders sign-off, the Atlassian tickets, the back-and-forth email chain between the graphics person and the developer about generating the properly-sized button image, or the failed accessibility review.

A more honest code test:

interviewer: “see if you can get this project my nephew made in high school to run”

job: getting the next project their nephew made in high school to run
