The course Automobile Engineering in Amal Jyothi College of Engineering is approved by AITCE, so that is a good thing. But, coming to the placement section, I didn't find much automobile companies. And, for getting admission there, I think you should give an entrance exam. I would suggest you to directly contact them and ask about the entrance exam, following is the link where you can find their contact details.
