First i got mail for HR video Interview. it was simple and covered the topic basic questions of why this company, why this position, OPT details etc., then they set me up for Telephonic Technical Interview. all questions were from the glass door and finally onsite Interviews( but i did made through telephonic)

There were three phases for recruiting procedures. The first stage was a brief and relaxing conversation, the second stage was about technical things and hiring manager asked several questions in the third stage.
