I applied through university. The process took 1 day. I interviewed at Ambarella in Mar 2014
Interview
Phone interview, approximately 1 hour. First the director introduced what his group is doing and asked one of my course project. Then he requested to write Verilog codes, including switching a and b in one clock cycle, explaining blocking and non-blocking, and implementing FSM of a pattern detector.
