I interviewed at Amazon Web Services (Columbus, OH)
Interview
60 minute interview, 45 minutes of technical and one behavioral. The Amazon interview prep material was not helpful at all since most of the interview consisted of thermodynamics and fluid mechanics principles. Know all the stages of the refrigeration cycle, specifics about pumps & compressors, along with how state functions change through the data center’s cooling cycle.
