Typically the people without side projects also make excuses to not do those either.
If I had a company I'd offer looking over an existing project or a project where you create a side project of your choice without any further direction.
So not mandatory but the easiest way to go probably. Once you apply to my company you'll have one to show for next time at least.
(If you want to write the project out on the whiteboard instead I guess feel free, that seems hard though.)
Many people do not have side projects. Few people working as software engineers were not tested in some way.
I think it's more useful and more fair to give candidates some direction when I request something. What scope is enough? What tests are enough? We define side project differently or you would expect much more time from candidates than I do.
I used to think so. But real tasks have acceptance criteria. Seeing how candidates work with loose criteria has told me more than telling them in effect to read my mind.
