I get how the interview experience can be inhumane and all, and I’ve been through my fair share of shitty interview experiences. But feeling disappointed about not getting feedback from your performance?

You’d need to assume interview feedback is constructive and relevant to your professional growth, interviewers are well-trained, interview processes are fair, and candidates receiving feedback are capable and willing to act positively on it. From my experience, having all of these factors be true isn’t all that common, and one of these factors is beyond the company’s control.
