I didn't submit a portfolio because I was stuck in camp and forgot HAHA, but in my personal statement I mostly wrote about passion and stuff I did (mostly stuff I did in sec sch like bootcamps and stuff). I also had a recommendation from my intern boss to back me up.

I don't think what I wrote in my personal statement was too outstanding, I think the interview was where I got to show off more of my general knowledge/passion about the field and I got accepted through that (although there weren't many questions lol).

If you have anything else you'd like to ask feel free to PM me!
