Systemantics India Robotics Engineer interview questions

The attitude of the interviewer was not good, he was chatting with someone on his phone not paying attention to what I was explaining. The decorum and the discipline of interview was not maintained, thereby insulting a post graduate in Robotics. Later, he had a discussion with the HR for half an hour. The HR rejected my candidature giving a lame reason that I do not have required minimum technical and presentation skills. In a nut-shell, "worst interview I ever faced"
