I have had hiring managers tell me that, almost verbatim actually, when I forgot about the interview and showed up significantly late.
I was embarrassed and yeah I admit that it wasn’t exactly fun to be called out like that, but I would much rather they say that than for them to pretend everything is fine, let me leave the interview thinking I didn’t annoy them, and then have it be a mystery as to why I am declined.
I felt embarrassed in the moment, and I should feel embarrassed. It is very rude and inconsiderate to not show up to meetings that you agreed to show up for and it signals that you don’t take the other person’s time very seriously.
To be clear, it wasn’t like I was being pedantic to the second; I know Zoom and Google Meet can be finicky so I understand being a minute or two late for a meeting and I generally don’t say anything if they are within the “my fucking microphone isn’t connecting gotta fix it” threshold.
"You don't value our time, you show up late, how do you expect us to value your time?"
Or something to that extent, that would be extremely rude. It's like a line out of Wolf of wall street or those trump movies - "You're fired!".
