The interview process took forever. I had a phone interview with my recruiter which was very standard it took around 20 mins to complete. I then had to call my recruiter every Thursday for a whole month until they were finally ready to interview me. I went to the office got there early (very key at Yahoo), I met with my recruiter for a few mins and finally had my real interview. I met with a man first (who became my boss). He asked me very standard interview questions about my work history. He was very down to earth yet serious at the same time. He then asked me some interesting questions like : "How many tennis balls can you fill this room with?" as well as "Why is a manhole cover round". It took me a while to figure him out., but once I did the conversation went very smooth. I then met with a woman who asked me the same past work history questions (very standard). After we spoke the man came back in and gave a me a tour of the office. I recommend feeling out your interviewer. If they seem very lax go with the flow don't be tense. If they seem very uptight be very serious. Yahoo is a very relaxed work environment so unless your planing on interviewing for a job very high on the totem pole don't worry about it!
