Very unprofessional. One of the interviewers asked me if I was married and scoffed at my answer (very odd question to ask to begin with). They did not hide whether or not they were impressed by my answers, rolling their eyes etc. I tried to answer questions using STAR method but they kept interrupting me, wanting 5 word answers. I gave up with the interview as it went because of their attitudes - definitely did not want to work there if this is how they are with just interviewees.
