well, not having the courtesy to write from an address to which I could reply if I had any questions is disrespectful to the candidate.

They expect it to be from a company that’s better at masquerading that their email is sent from a real human’s inbox instead of lumped in with the rest of their automated emails default config values.

Just because a message is sent from a noreply doesn’t mean it wasn’t manually composed and sent. I would expect rejection letters to come from such an address even if they are manually typed up.

why would you expect that?

I've been rejected from a few jobs that I've applied to at this point. honestly, this was the only time I can remember that it was an email, let alone an email from a no-reply address. every other time I've been passed on after interviews, the recruiter at least had the decency to call and tell me over the phone.
