Not a customer though, an interviewer who asks you how you'd go about designing the architecture for an IoT-controlled fleet of egg-cracking robots.

You might talk in great detail about SoA design, and the interviewer might be hiring for a monolith, but still respect the acumen, you could still be a great fit.

It doesn't mean the chef's only going to be cooking tasting menus any more than it means the engineer has carte blanche over greenfield design or to rewrite an existing project.
