Ask HN: Is there a site that list project exams that we have for interview?

I'm not talking about those useless algorithm test. I'm talking about home project that we have to perform using the language and framework of the company so I can know what kind of difficulty I'm about to get and practice on them.

I currently have a week long project to do at home and a week seems too much constraint on my time especially for the kind of job I applied to. So I want to see if it's the norm or not.
