I got the first interview at a career fair which occurred the next day. Than I was accepted for a second interview a couple weeks later and that interview was phone/webex interview where I did a presentation on my project in school. However, I was not accepted because they had already filled all their positions by the time of the career fair.

The HR interview was easy, asked me more about my academic projects and experiences. Questions are more situational like they ask you about how you handle things and stuffs like that.
