I always tell this cautionary tale when talking to friends turned founders. I was going to a 1-1 with a Director (Bob) in a FANG company. As I was walking to his desk, another Director and a Senior Director (Gus) called out to him that the meeting was starting and he should join -- he asked me to come along and tell him my thoughts.
It was a sales call with a 2-person tech company building some tools in the cloud native space. They were super eager, walking through the product. My manager put the phone on mute and asked "So what are we trying to do here" to the other directors. They replied "We just want to kick the tires to figure out how they built it, we're not going to buy". They let these guys pitch for 20 minutes, periodically asking questions and then muting to mock them. My manager nudged me to ask something, since I ran a similar initiative internally. I asked how they would handle a gnarly case we had and they didn't have a solution yet, but could come up with one (super eager, wanted the deal).
At the end of the call, Gus un-muted the phone and said "This looks great but I'm having a hard time following the demo. Can you fly out and show us in person?". The sellers paused and then started asking when the other was free etc, one was going on vacation but could "make it work" to come out the next week. Gus replied "Great, see you next week".
I left that meeting realizing they were all psychopaths. Notably, Gus had the charism of Gus Fring from Breaking Bad.
