I applied through university. The process took 2 days. I interviewed at Yahoo (Bengaluru) in Mar 2008
Interview
Yahoo! came to our college as the campus hiring process. We had following rounds in the interview:
1. Written test: This was the tricky part, if you answer more Unix/Script related questions interviewer will select you for systems engineering regardless of your answer in Programming side (Probably because not many people will master this).
2. 3 technical discussions: Generic questions, few can be tricky
3. 1 programming round
4. HR Round.
