For what it's worth, it can be worse, from an emotional point of view, when you do get feedback. I recently spent two full days working on a take-home assignment. I carefully addressed all of the requirements and spent the extra time adding in features that I know from experience would be useful in a real-world application.
Attached to the rejection email was a code review from the CTO which contained not a word of approval in respect of any of my ideas, but simply methodically picked holes in my entire approach.
This is my third rejection over the last year from roles that I had believed myself perfectly suited for. In the previous instances, I was ghosted after third-round interviews - that's a terrible feeling too, but at least I could persuade myself that an intangible personality issue had been the cause. But now, I have written evidence that I'm a moron. My self-confidence is completely shattered. Be careful what you wish for!
