Just anecdotally, I can confirm that this method works great - it screened me out by showing me exactly what day to day work was like at your company, and that I was not nearly nerdy enough about specifically containerization to want to do it all day.

So you saved yourself/the team several possible hours of interviewing, and me quite a few hours - I think it took me about 10 to 15 minutes to see what you wanted in an engineer and that I was not it, and a total of 1 email which felt quite automated (whether it was or not) so there was a very low social cost as well.
