Earlier quoted context omitted.
it's usually just a meet-and-greet. Yes, it usually is. But in this case the problem was that the CEO could unilaterally override the decision made by everyone else, so it wasn't just a meet-and-greet.
That is exactly the assumption I was operating under, I even called it a "veto". Does not change anything I wrote. (And of course the CEO can override any hiring decision anyway. The question is if they will.)
That's a huge red flag for any workplace. The only time you should ever consider taking a job at a company like that is if you're unemployed and you need the job and have no other prospects.
