Tevora Project Manager interview questions

I was reached out by a recruiter very soon after I applied on LinkedIn. First, the recruiter rescheduled the interview and didn't inform head up. Second, it was a video interview and he wore so causal and even sat on his couch....During the interview, he just asked some random questions, and it obviously both of us were not a match, he started laughing at my previous project I've worked on. Are you kidding???So unprofessional, who even cares to work in this kind of small company, especially after meeting this rude hr
