I can't imagine getting enticed away from a job by this kind of maneuver. All of these people are already, without exception, aware of Snapchat's existence. They probably also know that Snapchat, like everywhere else, is hiring like mad.

In terms of feeding the applicant pool, this is probably even less effective than the constant stream of LinkedIn recruiter mail. And more privacy invasive to boot.

Snapchat's target audience here also lives in the wrong city, since the article claims they are targeting Uber HQ in San Francisco. Snapchat's office is in LA.
