Looking for an internship this summer?  One of the key elements to landing an internship in your field of study is expressing a desire to learn a particular skill or subject matter.  Be specific – noone will hold you to it for life and managers appreciate someone with direction and confidence.  It is appealing and pleasing to  a future manager that you share their passion or curiosity.  It may foster an ongoing mentorship well beyond the summer term.  Even if you change your mind on a particular field of study, your temporary employer will likely enjoy that they were a part of your exploration and planning.
