In general, startups do not follow the professional practices of established companies. When you interview for an established company, they're usually professional and they get back to you afterwards. When you interview for a startup, you can run into all sorts of issues. The founder might not be there, the employees may have no idea what to do with you, or you might just have a 15-minute interview after traveling for 90 minutes to get there. They often won't get back to you. Though this example is particularly bad since they're asking applicants to do unpaid labor.
