Trending @Accenture; Help me in resign from accenture.

As, I am a fresher from tier-1 college for a 4.5lpa. I got into accenture. Till the joining date, I didn't got any other offer. I have no other options left. So, I joined accenture and regretting here with its policies. I would prefer to work for a startup for free rather than joining accenture. Humka nikalo nhi rhna iss company mein abhi to 3 mahina hi hua hai.. Jo seekha uspe kuch dete hi nhi hai.
