Thanks for posting. I enjoyed reading your profile and feel it was interesting and strong, congrats. You have a lot of things going for you, for example:
-outstanding GMAT (congrats!)
-excellent GPA and though average university, additional academic strength via the 5 year/masters degree included though
-STEM as you mentioned
-asian american female; programs tend to show interest in qualified female applicants and diversity in the classroom
-solid internship experiences
-study abroad/international experience is a big plus (and provides you with skills to work with others in different cultures, important in b-school and your future career)
-variety of leadership roles; particularly interested in #3 and #4 on your list (president of the Johnson & Johnson interns sounds impressive/unique)
It's ok not to feel you have something HUGE (i.e. 'I climbed Everest'!) in your profile, you can and should still aim to highlight what your PERSONAL 'wow' is, which may just be the experiences, traits and skills you bring to the class that are more unique. Through putting together strong stories and narratives in your application, you can show the admissions committee who you are and why they would love to have you in their class.
So I definitely encourage you to make time to work on the essays-- those are the application component that really shows who you are and can make a huge difference in the decision! You'll also want to have a feel for your short and long term career goals, basically the 'why' behind this application, for essays and interview.
These are difficult programs to get into, for sure, but not out of reach based on the info you've provided here, if you put together a strong application.
Let me know what other q's you have, and keep me posted on your progress!! Good luck to you.
