There mainly two ways to go for, one is the Job and another is further study i.e., BTech. Now if your college offers placements then its good for you but if not then you can apply for different jobs in the job websites. Now for BTech you have to go for the Lateral entry exam corresponding to your state. On qualifying the exam you will get the chance to join BTech directly in the second year. After BTech you can also apply for more advanced jobs and you can change your field of study from Automobile to Mechanical and so on.

I hope my answer helps. All the very best for your future endeavors!
