> Most people have still written code for school or a hobby project

School was years and years ago, and has nothing to do with my current skills.

From the people i personally know, most do _not_ have a hobby project, even fewer have hobby projects that showcases their technical skills. Nor should they be expected to. Most people have non-programming hobbies.

> I cannot understand how some developers have no code to show.

It's really not that deep, I'm worried if you really cannot understand. I don't code outside of work, I'm not interested in doing it. I'm good at software engineering, not passionate about it. I have a bunch of other hobbies. There's no reason I'd have any code to show now or at any point in the future.

> let them make a small project over the weekend and then do another interview where you ask stuff about what they've made

If I'm paid for it, sure why not I could do that. I won't love it but hey I'm looking for a job, I'll put the legwork in. But if this is the only or the "preferred" interview process for a company, I need to point out that it is deeply discriminatory as it advantages people who have the time to do a weekend project: for example it benefits males disproportionally (women do most of the care work in any country, also the most house work, also have a higher chance to be a single parent, all of which impacts the time they can put in a "weekend project" if they can do it at all).
