Interview process is very straight forward. HR called me and I asked her to schedule interview next day. Next day I attended interview. There were 3 rounds( 2 Technical + 1 HR). Technical interview was based on some core concepts of application development and technologies mentioned in my resume. HR was just for knowing each other, and HR explain lot of things about the company and their work culture. In that last when I left contata's premises, I was holding offer letter. :)
