I can echo what wtrresq2011 says...other Navy Officer accession paths (OCS, NROTC, etc.) are designed, in theory, to
teach the leadership skills necessary to be a successful Naval Officer. The direct commission path is looking for people who already
have clear and established leadership experience. Often, this comes in the form of formal management experience in your civilian job -- but it doesn't have to. Demonstrated leadership experience underlies all the academics, certifications, etc. As wtrresq2011 says, it can be in the form of community and volunteer organizations, fundraising, etc.
I started a
scholarship in the name of a strong personal and professional mentor to me. It is now a permanent endowment at the University of Wisconsin–Madison, and will make an award each year to a deserving future Navy or Marine Corps Officer at the NROTC unit here. The first award will be given to a student next month, and will do so every spring from now on. It turned out to be a lot of work, but it was worth it...and no matter what happened, this is a good thing that will live on and benefit others, just like volunteer work you might do in your own community.
I believe the process itself is part of the experience...
