I applied online. The process took 4 weeks. I interviewed at Flipkart (Palo Alto, CA) in Sept 2016
Interview
The interviewers were experts and knowledgeable in their domain. I believe all of them were Ph.Ds with 5+ years of industry experience in relevant subject area. They had phone conversation, followed by presentation on site, and then technical interview by 3 employees.
