I applied online. The process took 2 months. I interviewed at Flex (San Francisco, CA) in Mar 2015
Interview
Extraordinarily detailed, thorough and professional. The initial interviewer was professional, well prepared and knew how to engage in thoughtful, 2 way conversation.
It was a tough interview because of the time-1.5 hours-and the depth of the questions.
Interview questions [1]
Question 1
The most common question formula was, "describe in detail how you would handle, ABC problem?" The formula allowed the interviewer to ask good questions. The key is that he listened to my answers and responded accordingly. There was nothing canned about the process. There was a clear agenda, like anyone would have, but it was not scripted.
