There's a lot of terrible YC companies. 90% of everything is crap. YC is a good filter, so it's closer to 50% or less. Still a lot of crap. There are incompetent people who graduated from Caltech or worked at Google. Signals aren't perfect. YC companies seem to be extreme in some form or another, good, bad, and ugly. Do write it up on Glassdoor. It's a record and something people will check, investors, applicants, and competent HR. YC itself probably can't even act on it if they wanted. They invested money and if the company was bad enough, they'll die on their own. YC tops up money in a non-signal manner (only when others do). So even if they wanted to back out of an investment, they likely wouldn't.
