I was contacted by a recruiter for an initial discussion. After a short phone conversation with HR, I was set up for a technical phone screening. I was asked mainly about data structures and algorithms.

After a few days, I was asked to come for an on-site interview. The on-site interview consisted of five 45-minute one-on-one technical interviews. The interviews were mainly heavy on the technical side, asking about data structures, algorithms, and coding questions. Every interviewer asked me to write code on a whiteboard.

Make sure to have good data structure and algorithm skills before interviewing. Overall, the campus looked pretty decent. Yahoo has a really good working environment. I was told that they have very bright engineers, but senior management lacks vision. I found every interviewer very knowledgeable. If you have 0-5 years of experience, this place has good potential for growth.
