Yahoo just acquired a San Francisco-based startup called Distill, which was working on a way to make technical recruiting easier by pairing video interviews and programming challenges. They had raised $1.3 million in funding from investors including Felicis Ventures, China’s Innovation Works and DN Capital.

The startup’s two founders, Deng-Kai Chen and Ken MacInnis, came from Tapjoy, StumbleUpon and Google. They created Distill because they had built up engineering teams before and were familiar with the frustrations that come with managing and scheduling technical interviews.

Distill’s product paired the basic features of a video chat service like Skype, and put them alongside a text editor and file upload space so that an interviewer could walk a candidate through a collaborative coding session.

We hear they’ll be working on mobile ads products for Yahoo.

Here’s the memo the company just posted to its website:
