Someone I knew from school is starting a company. I connected with him over a video call for an informal interview. At the end, he said he could see the reflection on my face from when I switched windows to the note-taking app, and asked if I had been taking notes. I said yes. He said I should have asked first and that it was like recording someone without their permission.
I've never heard of this before. Is it recommended to ask for permission before taking notes in an interview or other type of meeting?
I know sometimes there are NDAs, but if there is no such discussion, I think the assumption is that note-taking is expected. I may have been taking a few more notes than usual, but that's because there was no written document prior to the meeting (e.g., there was no job description).
Sometimes I have trouble understanding how someone could think so differently than me, especially considering we went to the same school and worked for the same employer in the past.
Is taking notes in any sort of meeting or specifically an interview rude if you don't ask the organizer first? Also, I'm not really sure how he knew I was taking notes, though I guess he could see my hands typing. Should I change something in the setup?
