This. You should send an email to a recruiting director, head of talent acquisition, or even your recruiter (if it wasn’t them). This reflects very poorly on the company and their values. You can leave a Glassdoor review as well. For what it’s worth, it sounds like you got a peak at their work culture and dodged a bullet. If they didn’t want to spend time interviewing you; they’d definitely not voluntarily spend time with you at work to help you grow.
