Getting work experience has been central for me at my time at Wagner. I worked at a private planning firm last fall, since I had never worked in planning, and wanted to understand the field. I felt like I got a lot of basic, core knowledge from that job. When I was looking for my next internship/job, I decided to go to the opposite extreme - to look only in the public sector, and to look for a position in administration rather than planning (these are two of the roles that I'm considering in my future job search). That is how I ended up working for the Division of Citywide Administrative Services for the City of New York. I feel like through only 2 internships (so far), I've gotten a tremendous breadth of knowledge.
The feedback I received from OCS regarding revamping my resume was invaluable. Resumes are very personal documents, and their unbiased feedback helped me focus my resume more appropriately.
