Nasdaq Software Developer Senior Specialist interview questions

Round - 1:- OA. Very easy with basic java questions and easy problem solving questions. Round - 2:- Two interviewers from AUS where one is the HM itself. The round is scheduled for 1 hour and the tech person said he need to join another call in 30 mins. He asked me the very basic java question like static, final keywords and then he asked one question to read the data from csv file and sort and show in console. I have completed the coding and showed the answer too. Then he dropped off the call and the HM did not even asked any question and round was closed. Recruiters are so rude and neglegent. Nasdaq, Kindy look into your interviewers first, before rejecting the candidates. After multiple follow-ups with the recruiter, I have received an email that my candidate is stopped and not proceeding further. Such a time waste interview it is.
