I applied through an employee referral. I interviewed at Yahoo
Interview
Start to finish - background review, fit questions, logic and case studies, finally a walk through of a model based on an example interviewer asked. Overall process took a few weeks but that was considered accelerated so I'm not sure what the real time frame normally is. Everyone was really really friendly and made sure I felt comfortable - which made it difficult to determine if I was a great fit or they were just nice.
Interview questions [1]
Question 1
Walk me through how you'd build a financial model for forecasting X for Yahoo. I'm not sure I can share the X part but know that you'll need to know your modeling inside and out.
I applied through an employee referral. The process took 1 day. I interviewed at Yahoo (San Jose, CA) in May 2011
Interview
Internal referral is somewhat required to get my resume noticed. Then phone interviews with the team for 1.5 hours. One week after, get the invite to visit their Sunnyvale campus. 6 interviews in row, with the last one as an unexpected excel test.
