Do you have Electronics Design already? if not it will be difficult to make a case. You might need the layout of the electronic components/peripherals. If you have no references and if it is a new product, you have great freedom to display your creativity, probably what the recruiter is looking for. Start with a rough case of what you think is optimal for the need and go on building/editing/changing/redesigning from there. I am afraid I cannot help you further with the informaiton you have given.
