All 7-8 interviewers were friendly and didn't put me under too much stress. Questions were easy-medium. I was tested on technical ability, background, and most importantly on communication skills. There were 3-5 guesstimate questions asked. Some questions were on design, how would you design X feature of whatsapp etc, which is your favorite product and all. I was also asked to write a paragraph on what and why of product management and how I would contribute to the team and the role and the company. To and fro air tickets and transportation / logistics was taken care of by the company.
