Intercontinental Exchange interview questions

I had the worst interview experience here . The interviewer laughed from the very beginning when I didn't even start with my introduction . It was really demotivating to have such an experience during an interview session . I actually thought his abrupt laugh might be for some other reason but he actually laughed many times during the interview for no reason .Very Unprofessional and demeaning behaviour. I would never like to be a part of such an organisation where employees themselves lack basic ethics while representing their organisation in an interview .
