Applied online. Got invitation for first phone interview after some time. The first interview was half hour long and was mostly technical. I was asked about basic issues in digital design. After the first interview, i was invited for a second phone interview after a few days. The second interview was one hour long. I was first asked details about my doctoral research. After that, there was another round of technical questions on digital design. About three weeks after the second interview, I got a call from HR that my internship has been approved. I received the official letters about a month later.
