Striim interview questions

Required to do a thorough project which I think should have been paid. Was given a verbal job offer only to have it retracted after standard negotiation questions. It was very shocking and unprofessional. I wanted to at least have a conversation but they ghosted me after the email. The email was also full of legalspeak and very vague, which is why I would have at least appreciated a phone call. I dodged a bullet.
