Ask HN: Companies That Use Take Home Projects for Interviews?

I'm an experienced developer (previously worked for Microsoft) who left to pursue building a SAAS business. Unfortunately things aren't going as well as planned and I've been looking for work over the past few months. I've had several interviews but no offers. Although I used to be pretty confident in my interviewing skills, I seem to be tripping up on the technical portions of the interview. Usually on things I wouldn't struggle with.

I've seen discussions about companies that give project based interviews, but have never seen one in the wild. I'd be happy to complete a small project to show I'm competent, I just don't know which companies to target.

About me: All professional experience with .NET stack (willing to learn others, if given the chance) Located in Seattle (Remote would also be an option).

Thanks in advance for your suggestions!
