Applied through Career Fair on campus. Received a follow up mail requesting for phone interview. First interview was informal asking why I'm applying for this position and some other basic HR questions. Next there was a technical phone interview. It lasted for about an hour. Questions were from the topics - Math, C++, MATLAB and Control Theory. very technical and specific. Final round was on site at Natick, MA. They had one technical, one HR and one Managerial interview scheduled on the College Day. Got reply within the next week that I was selected.

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.
