Synalogik Java Developer interview questions

A coding test to be taken at your leisure and submitted via github. The problem is fairly straight forward with some deliberately vague requirements. I submitted my solution and was told that I had not got through to the next round. I was given absolutely _no_ feedback explaining what I could have done better. IMO this is incredibly rude. If people have spent a significant amount of time on your process then the least you can do is to provide feedback. Just reiterating the criteria (as in the HR response to the previous complaint about this) isn't good enough. If this is how they treat people, I'm not sure I would want to work there.
