The problem is that the OP’s resume reads like that of a 35 year old, not an 18 year old. The OP risks looking like s/he’s heavily exaggerating a number of EC’s, which results in making all of them look suspect. For instance, a human resource manager would usually handle things like complicated benefits issues and workplace disputes. I have a really hard time believing an 18 year old was filling that role in any meaningful way. I also can’t imagine anyone taking wealth management advice from a high schooler.
The internships are believable, but not particularly impressive in and of themselves. Self-publishing a book also doesn’t mean much. It could be an amazing book, it could be worthless dreck. The TEDX talk intrigues me.
@bronny, my advice would be to avoid fluffing up your experiences. Pick the most meaningful and focus on those without exaggeration. Excel as an undergraduate and you can apply to Ivy MBAs.
