First off I had to give an online test, which asked me a series of questions about myself and a few math questions.
Next I was interviewed over the phone by a manager and HR person for an hour. Mostly STAR format questions.
Finally I was called on site where first night I was given the tour of the data center.
Next day I had 4 rounds of interview. Again all STAR format questions. 2 interview face 2 face, 1 over the phone, 1 in the video conference room.
After working as an intern fro 3 months they offered me a full time job
