It was behavioral interviews for the most part (phone+onsite) . I had a screening with the recruiter, a group phone interviews with two hiring managers, and a four-round on-site interview.

I was interviewed for multiple positions. The process was fairly lengthy-just about 90 days from contact with the in-house recruiting team until finally being told that I was not selected. During that time I had multiple interviews with a wide variety of people, and four things became very clear: 1) They are working hard to reinvent themselves, and Marissa Mayer's name is on everybody's lips. To the point where I kept trying to think where I had met this person everybody kept referring to so casually but earnestly by first name, as if they had just been talking out in the hallway or I had met her in an early conversation and should have remembered what she said. 2) They are very middle-management heavy. I met multiple Directors and VPs without having a good clear sense of how they all roll up. 3) If you don't already have a Silicon Valley pedigree, you're probably not going to be seen as a good "culture" fit. Which is both understandable (any hire that raises eyebrows right now is high-risk) and very frustrating. 4) There is a pretty high chaos/newbee factor. Many of the people I spoke with were themselves very new to Yahoo, and there seemed to be a lot of job-switching and task handoffs along the way for those who had only been there for a few years.
