It’s fine if I’ve asked you if you have any questions for me about the company/job but if I ask you about your experience or your thoughts on a topic and you starting reading then we’re done.
I already don’t like it when people parrot my company’s marketing site back at me. Saying “I see on your site you say X” is fine but trying to work it in naturally (as if it was their idea) feels forced and borderline deceptive/manipulative. It’s like they are expecting me to say “On wow, we think the same way! How cool that you came to the same conclusion/idea/etc” and not “oh, I see you read our website and are parroting it back”.
It’s the same way that some interviewees with about-face on something they just said when they realize they stepped in it. “I don’t like X language”, “we use X language here…”, “I mean I like X language a lot and can’t wait to write more of it!”. Don’t just tell me what you think I want to hear.
