Pros
Kyocera has lots of great people working there who strive for quality handsets in a timely fashion. Their dedication and good nature make the place fun to work, with a fairly relaxed atmosphere.
Cons
Management has "managed" this company to the ground by concentrating on things that do not yield better products; things like perfect 5S, RINGI, or its amoeba management style. They have consistently ignored and furthermore put roadblocks in front of things that would have made the company successful from within, in favor of lay-offs and ultra-conservative approaches to manufacturing and design. Kyocera has re-defined the meaning of ultra-low tier handsets through use of extreme cost-cutting measures and cookie-cutter like phones with no personality. Most of the time decisions get made because of cost not because of customer satisfaction.
