It was a walkin interview and I was referred through my friend who happens to work here. When I went there the HR collected my resume. First round was an introductory round with couple of technical questions. Second round was technical round which was solely based on the projects I had worked on in my current organization and side projects I had developed. Third round was HR round where I was asked my expected salary and notice period and reason to leave current organization. Last round was negotiation round where I was told my CTC and joining date and an overview brief of the company.
