I think people are just upset when they submit a resume, or even go on an interview, and get NO response at all .. I don't think most people care about feedback - they just want a response. A one-line auto response would be fine.
Yep. As an undergrad, one of my first "proper" interviews was with Mozilla for an internship. I was obviously super excited since I actually cared about their products. I spent a lot of time carefully preparing for the two rounds of interviews, just to get ghosted! Sent a follow-up email a couple weeks later -- no response! I was crushed!
