Maybe it's cos my whole working life has been in MNC, but to be honest I don't understand at all what's so great / prestigious / whatever about working in one. It's not like life is a bed of roses, and it's not like other people worship the ground you walk on just cos your business card has a familiar logo. We also work long hours, also have sh*tty bosses, also have lots of pressure, also always feel underpaid ...

Though I guess if I had to give you advice about getting into one ... it's not as hard as you make it sound. Your (relatively) bad CGPA isn't that much of a handicap. What wtfoo said is quite true though. Likely for any opening, your resume will be one of 50 landing on the hiring manager's desk, how will you make yours stand out so that you're called to the interview? And how will you make yourself stand out during the interview?
