AppNexus has over 1,000 employees and has probably hired almost that many more on top of that over its 10 years as a NYC startup--so, obviously, they've had to get pretty good at sourcing top candidates.

Lorraine Buhannic has been on their recruiting team for six+ years and has seen every app, every channel, and measured every pipeline ROI you can think of.  She takes us through the recruiting process, what they're using and what they're not and what the inside of a recruiting team looks like that got AppNexus up to being a 1,000 person company.
