Take home projects are not work from the company’s backlog. They’re tests and all candidates receive the same test.
It doesn’t make sense for a company to open up their code base and infrastructure to random candidates and ask them to work on it. That’s an IP and leak nightmare.
OTOH, if you are taking a paid contract job to work with a company on real work as a trial, you could definitely be violating contractual agreements with an employer. This type of interviewing is extremely rare, though. Few full time job holders would consider it, so it would be largely limited to unemployed people who have the time to do it.
