Affinity Software Engineer interview questions

After applying online was contacted by Recruiter to set up a tech screen. Had a really terrible interview experience, the interviewer started the interview without any introduction, straight to the coding question. The coding question was a really simple implementation of a game. The implementation was done before the time so the interviewer asked some follow up questions which i implemented as well.The follow up implementation had a minor typo which i figured out and started to explain.By the time i tried to rectify it he abruptly ended the interview session on the coderpad (which was well before time - 5 mins in advance to be precise) which i found really rude. Have interviewed at tons of company but never had this kind of experience. Won't even think of applying here ever again.
