What kind of accommodations would suit these individuals?

Relatively small but not too small take home project plus live code review and discussion of approaches they took in the project.

When I used to be a manager who did hiring, I was always open to accommodating the candidates needs. Like instead of whiteboard, using paper or laptop. So far nobody asked for take-home projects. A few times people asked for a second chance and I'd agree to it.

How does competition programming style interviews discriminate against ADHD?

I know there's different types of ADHD but the type I'm most familiar with is the one with a relationship between attention/focus & stimulation.

High stimulation = high attention/focus. So interviews wouldn't be a disadvantage at all, unless they were incredibly boring.
