well, i didn't get in to SIPA so i don't want this to sound like sour grapes. However, i too had nothing sent to me after my application. i did ask them a question during the application phase via email and never got a reply. nada.
i have a number of friends who did grad work at columbia all across the spectrum. My law school friend didn't like the school, but did say the career services was awesome.
My other 4 friends who went there dislike it from top to bottom. My friend in the social work school asked about an alumni database to use for networking purposes. they told her it was on a card system (this was 2 years ago) and if she had a specific name she wanted to look up they could get back to her with the individual's information in a week to two. now, obviously this isn't the same program, so grain of salt and all that, but it's stories like these that made me decide against columbia long before my decision letter arrived. my undergraduate experience was the polar opposite of this, and so i'm definitely spoiled. But, while i'm more than capable of doing a lot of legwork on my own, if tuition is that high, i expect to see some return.
congratulations to those who got in and i sincerly wish those of you who attend the best of luck. ny is an amazing city full of opportunity and obviously SIPA has its great points. hope to meet you in the field one of these days.
