I just spent the past month looking around for interesting new work after quitting my last position. Two of the ten or so smaller companies I've interviewed with so far had work-sample-ish tests as part of the hiring process: Keybase and AltspaceVR. Both of them had already made my short list of potentially ideal companies to work at, and I had ample time to ask them questions and chat before doing the work sample project. (At Altspace I went and had lunch with the co-founder and the director of engineering, and also tried out their VR software.) I felt no compunction at all spending 2-3 hours doing a interview project after that. Afterward, it was clear that both companies read my work and judged me based on it. If companies were cold emailing me on LinkedIn asking me to do their two hour project, I would not do it, but neither would I bother going to interview with them. Given that I'm already cherry-picking which companies I care about, I don't mind investing some time to make them care about me. EDIT: I agree that it would be nicer to spend time doing something really useful. I hope that if I handed them a FOSS thingy that was representative of my ability, that these same companies would respect that in lieu of their work sample -- although standardization is valuable for evaluation purposes, so I can understand if they wouldn't. (I just did the projects they suggested because I thought they sounded fun.)
