Will entry-level development roles disappear?
They change. Tasks often given early in a career, like tests or small fixes, are the ones AI does best. So you need to show earlier what else you can do: understand a need, review AI-produced code, own it.
Do you still need to learn to code?
Yes. You cannot check code you do not understand, or design a system you could not write yourself. AI speeds up people who already know; it does not replace learning.
How do you show in an interview that you can work with AI?
With a concrete case: the code the assistant proposed, what you fixed, the tests you added and why. That shows both your mastery of the tool and your standards.
