This is terrible advice for companies and interviewees. We've successfully used "homework" project when a candidate had potential, but didn't do well in-person for various reasons (nervousness, time pressure). In many cases we've hired them when they can produce something and talk over it afterwards. Without this, they wouldn't have received an offer. While I get they said "which are not sufficiently interested in them." but it's still an interview process to see if we should/should not hire.
