This is possibly the most common reason and, unfortunately, often the only reason, why students choose an internship. It is the preferred factor of students who have either put off the search for their internship or lack confidence. Taken by itself, this is the least recommended reason. Remember that in most cases internship agencies want you. The situation is different from applying for a full-time job, then there are often several dozen candidates.
Many agencies only have one or two candidates for an internship position for any given semester.
You don't have to jump at the first agency willing to take you. Unfortunately, many students often do. It is good as a secondary consideration. It is not generally advised, however, as a primary consideration. Examples of such attractions might include skiing in Colorado, mountain-sheep hunting in Alaska, or watching Bulls basketball games in Chicago.
