Triplebyte co-founder here. We understand how frustrating it'd be to spend time on a project and then have no one read it, we won't be doing that. In our process, you schedule a time to talk with us about the code you've written. We'll go through it together and provide feedback.

We're not replacing talking to another person part of the interview, we're just trying to remove the awkwardness of having someone watch you code (for those programmers who want it).
