isn't this question in the context of a face to face interview already? so you're setting aside time to talk to these people for 30+ minutes anyway. is it really that difficult to spend a few minutes scanning the company website / eng blog and finding at least something that you could say looks interesting?

i feel like if you're talking to so many companies that this would be too much work, it's probably useful to focus on tightening that funnel so more early interviews turn into offers.
