Interview
Interview suppose to be 3 hours, lasted almost 4 1/2. Interviewed with several people who all read the same questions from the same script. The toughest interviewer was HR. She didn't sit down for most of the interview and her phone rang constantly. She seemed to be disinterested in the process. She wanted to know two weaknesses and seemed to hone in on your response and try to apply how it would be an issue at the company.
