I am in my final semester of B.Tech and have got a job offer from Amazon (CS). What should I do to get into film and acting?

Follow your heart, which will only take you to the right destination. Do not do something to please someone. I am saying this, because I don't understand why did you get into B.Tech? If you want to be an actor? Anyways, once you become successful, people will value you truly automatically, so don't

Congrats, you should not take risk with your career. And with job, you can also do films, but I think you should take the job, otherwise your degree is worthless.
