Benchmark Arts interview questions

The initial remote interview was positive and lead to an additional remote panel interview. The third interview was an in person visit and shop tour. During this visit the owner criticized the former employee for leaving the company and accused me of wanting to steal electricity for asking about their EV policy for plug in vehicles. Less than 1 hour after that interview I received a decent offer however I was pressured to accept it on the spot without any time to read the offer whatsoever. Initially I accepted and they told me to direct any questions to their hiring manager and/or HR person. After I emailed some general questions and one about employee culture they lashed out, accused me of being negative, and withdrew the offer. I thought when they told me I could ask further questions they would be less annoyed and angry than they were. In my opinion when a company tells you their culture is a "family environment" it's a big red flag.
