I had a thread on this a couple of weeks ago.
Doostang lists some awesome jobs. In fact, I’d say that at least half of the jobs I’d want to apply to on indeed.com link to doostang. On my original thread some people found the site helpful while others got nothing out of it.
On the web, I have read that some of Doostang’s post are extremely dated.
Finally, Doostang was created mainly for Ivy Leauge grads. If you notice, a lot of the people who got jobs (posted on Doo’s website) were grads from MIT, Harvard, Yale, Stanford, etc… Now if your like me, I didn’t go to one of these schools so it may not even be worth your time to apply via this site.
