Hi globalhopscotch
I can understand the frustration and confusion that you are currently going through...But I have a thought that I'd like to share in this regard...I am not studying at WWS but have some friends there and interactions with them gave me few interesting and unique insights...
WWS offers a highly funded program and hence, seeks to admit candidates who realllly deserve it...They want people who are driven by passion, not by career goals, brand, money, fame, prestige blah...blah...etc...I guess they look for genuine interest in public service instead of derived interest...For example- lets consider 2 applicants, A and B...A got the best grades, GRE scores, great work ex, recos, SOP etc and B undertook a self initiated project in his/her village that transformed the lives of 200 farmers...I guess in that case WWS will pick B over A because while helping the people around him, B had no motivation to get into WWS...he just did what he believed in...I guess, WWS looks for people who dont do what they do just to get into an Ivy League school..they want people who can change the world and be future leaders...
I just tried to give you an honest insight...I might be wrong..but this was just a food for thought... All the best ...
