Absolute waste of time and money. The faculty (Srikanth) is under qualified to teach the subject. He is extremely rude, arrogant and constantly derides his trainees who ask questions. Also, he does not have relevant experience owing to his qualification. He is just a jumped-up office boy who is now working as a faculty. That explains the quality one can expect here. Evasive manoeuvring or snubbing is not the way out for a faculty.
