I’m a junior and I’m currently completing a paid internship for a big no profit company in DC (as of now the internship is from January 2016-August 2016). I am the web designer for the analytics team and one of my bosses is nationally known and works for the National Science Foundation.
How would colleges (specifically top/selective colleges) feel about this?
Awesome! Make sure you get a letter of recommendation from them as a supplement and also document what you do there on a weekly basis in a blog. I have found that it has more impact when you show what you have done than just saying that I have done this.
