CitiusTech Senior Java Developer interview questions

Terrible process. The interviewer was just rude as hell and was quite clear that had zero grasp on oops concepts and coding. He kept interrupting me and gave me a leetcode hard problem and kept poking me with too much "tch tch" while was I was trying to understand the problem. The HR was equally rude as she kept texting me and calling me throughout the interview asking me to join when I had joined and had also dropped a mail that I had joined. Terribly u professional company with no coordination or behaviour standards at all.
