Hi Aspirant 

First of all you must earn a bachelor degree in 'Automobile Engineering '.Then you should build a portfolio both online as well as offline.Let me tell you nowadays engineering jobs are not easily available.Even the company has vacancy for fresher and you are fresher but still there will be problems for you.There will large number of students who are freshers but they have experience .They gain it by doing internships.So don't be a fresher without experience.

Try to learn skills which is required in market.Do some internships and then you can apply to the company who have announced their campus drive or off campus drive.You can apply to companies online on: LinkedIn,Naukari.com,Indeed.com,Monster India .com

Be ready to face any kind of challenges.
