One Phone interview and 3 skype interviews. The phone interview consists of basic questions to confirm that you are a Computer Science Student. The following 3 skype interviews are 2 from future colleagues and one from future manager.

A phone screening by HR just to identify you are a CS student and know the basics. Most questions are in glassdoors itself. Then a skype screening with general discussion and a coding question related to the team. Once that is done there would be two more skype interview one with the hiring manager and an engineer from another team.
