I think that it wouldnt look like a conflict of interests at all. You are still at a very early stage in preparation for med school and if anything this would look good as you are keeping yourself busy during the summer which is what many med schools like to see. However, i advise that if you do participate in this activity, try to learn something from it or grasp something positive from it. Dont just do it for fun/money. Make it a positive investment of your time. i mean if you were to just work at mcdonalds for the summer flippling bugers (which isnt a bad thing).......would that look as favorable as working for an advertising magazine where you got to see first hand the inner workings of article editing which helped you later on in the development and publication of your own scientific research article at a lab in school? Just make it work for you, and make it an asset to your unique background. Try and also do some other things as you do this so that med schools can see you can handle a many things at once. perhaps some volunteering or shadowing. hope this helps and good luck on your endevour. 😳
