I would suggest going to the MNC as a fresh graduate. You should look at the annual salary package for better comparison. It is better to have private sector experience while still young. I am 29 this year and have been working in MNCs since graduation. I enjoy the culture and dynamics of the work which I dont think can be adequately achieved in public sector. I have a scholar friend who went to public sector and regretted his decision. I believe its more of the culture and red tape.
