I attended their campus recruitment held in my college. You have to clear three rounds of test before getting a job. First round is aptitude test. If you clear that, you will asked to participate in group discussion. trending topics on sports, economics etc will be given to a group of 8 people and asked to discuss on it. Just if you speak something about the topic, you will be selected. They just test your courage to speak and not on your knowledge on the topic. Finally technical interview. They asked me about my in-plant training.
