Are they worth writing -- i.e. why i want to go to ucla/northwestern -- if i truly have no idea why i want to go, except that they are good schools with good job placement??
Also, the NW optional interview -- how important is that? If I elect not to take it, will they judge me negatively? I'm actually a good interviewer, I think, but I don't want to spend 400$ flying to Chicago, when NW isn't a top choice of mine...
Thanks.
