Dear Samanta, if anyone says he/she became a software engineer right after 10th, he/she is lying. There is a academic procedure to be followed to become a Software Engineer. And against the popular note, Software Engineer is a designation. It varies from Organisation to Organisation. In few Organisations you might be called a Coder/Programmer/Developer. Now to get to that path, you need to study Physics, Chemistry and Mathematics in your 10+2 and appear for JEE Mains which is the major entrance examination for admission to B.E/B.Tech courses across India. After studying B.Tech preferably in Computer Sciences and doing certain software courses, you will be eligible to appear for interviews for the position of Software Engineer.
