MixPanel is looking for interns, and to drum up interest their founder, Suhail Doshi, shares his story of an internship with Slide, where he worked directly with Max Levchin (tech founder of Paypal). It makes some good point about why doing an internship at a startup makes sense, from the interns' point of view.
As an aside, this is the first time I've googled a tech startup founder's name plus the word "Twitter" and found no Twitter account. Instead, I did find a Quora account.
