They contacted me first through a phone, asked me about my expectation of the salary what my recent project were about. The first interview was to talk about myself and what I've done in my studies. The second interview was about preparing a presentation about the machine I was supposed to work on. It was pretty difficult because the machine is not easy to understand. Took them about two weeks to let me know I didn't pass the interview (via a phone call).

2 interview rounds. #1 with hiring manager  with a panel of 6 interviewers. Some of the interviewers had a good grasp of subject matter and dug deep into my work experience. But, a few literally asked me question which were clearly out of my expertise and hence setting me up to fail.
