Yahoo Senior Software Engineer interview questions

4 rounds of Interview in one day. First round was on problem solving. Second round on puzzle and analytical skills. Third on java. Fourth on design. But HR took time to revert back.

First time through was quite a cursory interview. I had come from Microsoft, where I interviewed in the late nineties. During that time, Microsoft interviews were infamous for difficulty (now they would be akin to Google interviews). My Yahoo interview, by contrast, was cushy. When I came back to Yahoo a second time, I didn't even formally interview. We just set up the HR appointment and went through the motions. That explains how Yahoo has bloated in the way that it has.
