I think you have great chances to reach your goals and don't let anyone tell you otherwise.. You have an amazing GPA and great post college experiences.. In my opinion it really comes down to your GMAT score.. If you can score high you definitely have a shot at top 5 business schools which will open doors for you to get into consulting and investment bank.. Reach for the stars my friend!
