I found this internship through LinkedIn, which is my first piece of advice - use LinkedIn! Second, I would encourage others to just own what you have going for you. I do not have an impressive portfolio. In fact, I barely have one at all - I applied with PDF attachments in an email! Embarrassing in hindsight (and honestly in the moment too), but admitting to what strengths I have yet to develop and just putting what I do have out there created a space of vulnerability that was seen as potential.
