Hexaware Technologies Java FSD interview questions

I had a very bad interview experience with Hexaware. The role was for a Java Full Stack Engineer position in McLean, VA, for Freddie Mac. The interview started at 1 p.m. EST, and the interviewer was based in India. The video and audio quality were laggy at first, but they improved after a while. I won't comment on his questions, but he sounded exhausted and uninterested throughout the interview. After 30 minutes, he abruptly exited the video interview room without saying goodbye or offering concluding statements, comments, or feedback. This act was not only unprofessional but also showed a lack of respect for my time and professionalism.
