Dude. I just finished working for a YC company that not only demanded a two week trial period, but after doing that trial period instead kept me on a contract billed for eight hour days but then insisted I must be in the office from 9 - 6:30 (their "engineering hours"). They wanted me to work close to 50 hours a week for no health insurance while underpaying hours and forcing me to attend all company events including weekend "hackathons" (haha so fun). It was a nightmare and I'm glad to be out of it. The irony is that it was a company that prides itself on giving people stable jobs and healthcare.
