I can remember interviewing at Google on a whiteboard, with an employee who was: disinterested, overly specific, and antagonistic. Left that building wondering which was less healthy: my anxiety or their culture.
It wasn't entirely clear to me if it was part of their culture to be overly dismissive of the applicants perspective and expectations in working somewhere or to intentionally test your reaction to contrived behavior..
But assuming behavior was contrived tests, why would you want to work for an employer that is tuning on who to hire by making sure they can abuse them in certain ways?
There's probably no sense in trying to fathom anything about why a company seems ugly when you can just move on.
