I received interview invitation through email. The person who attended the interview didn't introduce himself, so i don't even know his name. No salutation. No hi, no bye. Very weird interview with extremely toxic vibe. He asked some medical questions, they were easy and simple, but that's it. He commented about my facial reaction on one of the questions and ended the call abruptly!! As if I'm talking to my ex-wife. Zero professionalism in anyway shape or form.
