That's too bad, in this case I had a particularly good experience. I handed in a tarball, not a repo, so they didn't track time. No idea what other candidates did, but I got specific and positive feedback on the code submitted. The task was pretty carefully thought out and presented to not lean too heavily on specific patterns or techniques. All of your experiences do sound particularly frustrating, I wouldn't be too excited with them either!
