I interviewed with Cisco once. They wanted me to do a take home interview. Implement an api, make a web app, host the GitHub repo somewhere, host the web app so it was publicly available for them to test, make sure I included full documentation and test suite. A fully tested and deployed full stack application, from scratch, as a “take home test”. I said “no, I don't work for free”.

That was by far the most egregious example I’ve encountered of “we are trying to get unpaid labor from our interview process.”

I think it's reasonable if one's applying as a full-stack developer, the app is something like a simple TODO list that isn't anything they'd actually use, and there isn't a high expectation of polish. Few hours of work at most, not days, and definitely not a first-interview thing. Expecting you to host it yourself is definitely unreasonable: they can build and run it themselves if they care that much, but eyeballing the source ought to be good enough in most cases.

Yeah, that's ridiculous. It's not just FAANGs that pull this crap.
