Andrea Burbank joined Pinterest last summer from Microsoft where she worked on Bing.
She landed at Microsoft from Powerset, a company that created a natural language search engine. It was acquired by Microsoft for $100 million in 2008.
Pinterest, a social networking site popular with women, is also becoming known in the industry as a great place for women engineers. So far it's nabbed them from Apple, Quora, Google, YouTube, Bing/Powerset, and LinkedIn.
