We've been having drum corps/resume related conversations with our daughter, who will march her sixth summer and age out this coming season. After five years with the same organization, she's considering auditioning with BD and mulling the pros and cons. If she stays with her current corps, she stands a good chance of being section leader, and she already has a lot of ideas about what she would like to do in the position. If she auditions and is accepted by BD, she stands a good chance of getting a championship ring. Something we've pointed out is that, when she talks to potential employers, unless she's applying to tech somewhere, they're not going to care that she plays the mellophone well and marches cleanly. They will, however, be impressed if she explains that she took the five-year investment that the corps put into her and returns it by helping to make her section be the very best it can be in a potentially very exciting year for our organization.
Also, her dad works for a major retailer and does a LOT of hiring, including department managers, pharmacists and optometrists. He told her that most everyone has the same major-related campus organizations on their resumes, it doesn't mean much unless you can show active participation and leadership in that particular organization. Just going to the meetings doesn't cut it. So, basically, it doesn't matter so much what you are involved in as how you contribute while you are there.
Good luck with all your pursuits!
