No feedback is extremely irritating, but common. I know a lot of companies are afraid to give feedback because they don't want to get sued. I worked at a startup where we did give people feedback, immediately, and they were often very surprised. Companies may reject people who are otherwise a technical match for lots of reasons - maybe there was some personality quirk of the interviewer where he didn't like you. It's also hard to hire someone who is smarter than you. And of course your unfortunate experience is just one anecdote. I hope you found another job that evaluated you better. My current company was getting some poor candidates who passed the phone screen (the phone screen was the usual 1 hour code something in a google docs while we both look at it) type of screen. So we added a homework problem that takes a couple of hours to pull off. I found when I interviewed I had no interest in coding or following each companies stupid and arbitrary interview process. I do worry that it's too much of a pointless pain - but we have been able to reject a few people at the "homework" stage because they were just atrocious. If someone has been a public github contributor, that should be even better than a homework problem.
