<p>For everyone who is interning, there are a couple ways to show it off in your application. First, you must list the internship in the EC section--just the title, dates of employment, and a brief description of what you did; you have to put it in the EC list to put the adcom on notice. Second, you could write about it in your essay if it has a substantial impact on you, your future career goals etc. If you don't want to write about it in your essay or you don't have room, you could attach an addendum [like 1-2 paragraphs max; in the EC list say 'see addendum for detail'] that states what you did at the internship, what type of projects you worked on, what you learned etc. Finally, you could show off the internship with a recommendation. </p>
<p>Recs are tricky because you can always send in 1 extra, but you don't want to send in too many. Also, the same rule applies for outside recs as for teacher recs--you want the writer to know you really well and to be able to speak about your abilities, give some examples of outstanding projects you've done, and how your personal qualities will help you succeed at Wharton. If you're getting a rec from someone you've interned for I would REALLY sit down and talk to them about it and let them know that it should be a specific recommendation and that it would be nice if it discussed the types of factors listed above [not just a 'Joe is a nice kid, smartest HS student I know, and will do great at Wharton' type of rec]. DO NOT just assume that because someone is an attorney or other highly educated professional, he will know what to write in a rec because people tend to forget about the admissions process once they've been out of school for a while. People tend to think that recommendations should just make these grand statements of how great an applicant is and how wonderful he'd be at that school and don't want to include examples because they seem trivial. In contrast, examples of the type of work you've done or how you worked hard in a particularly difficult situation is what helps the adcom learn more about you. </p>
<p>The other thing to think about with an internship rec is--will it give off the impression that the writer doesn't know you really well and you're only sending in this rec to influence the adcom? You'd be shocked how many people do this; lots of people work for senators but only meet the senator 1 time in person and get a rec and all the rec will say is 'X is a great kid and my staffers say he does a good job.' If its that type of situation, its much better for your application for the rec to be from the senator's staffers or the judge's law clerks that you worked with daily because they actually know you. Same for getting a rec signed by a CEO + board of directors. Its easy to understand that you got to work with the CEO daily in a small/mid size company but does every board member actually know you and your work? If not, then do not get them to write or sign a rec because it'll look kind of obvious--particularly for a large corporation where the board is larger than just the CEO, CFO, COO.</p>
<p>The procedural part of handing in a rec is the easiest. Just get them to fill out the small form that goes with the letter and write the letter, and give you both in a sealed envelope--you just include that unopened envelope with the rest of the application. If you've done an internship and aren't way over the recommendation limit, I would hand in an internship recommendation. But realize that internships are not that uncommon for Wharton applicants. Thus, a particularly stellar internship recommendation may push you over the top but the internship alone may not; thus, do not assume that just because you worked at Goldman Sachs or worked for an influential gov't office, that you're automatically going to stand out in the applicant pool by virtue of having that name on your resume. Instead, use that internship as another way to show the adcom more about you and why they should accept you.</p>
