Pros
Excellent work conditions and environment: flexible hours, vacation (starting with 7 days/year to reach a max. of 28 days after just 4 years), state of the art scientific instruments, numerous libraries, gym, cafeteria, convenience stores and dormitories on campus...
Cons
*ITRI is more 'r&D' than 'R&D'-oriented and sometimes it is just 'r&d'. Innovation should be the rule but (in several labs, at least) it's rather the exception; sometimes the projects are just slight improvements of devices and processes from North-America, the UE and Japan . This situation is due to low dotations from the government, cautious investments from the local industry and low technical/scientific skills from many project leaders. On top of that, or because of that, R&D projects are often funded for 1 or 2 years which is, of course, a real innovation killer and a source of a lot of frustration for motivated recruits... *Chances to get a permanent position is very slim for foreigners.
