had a few friends working in Jap firms:
Rule #1
if you are not Japanese, forget about promotion and senior mgt. U can work until cows come home...they will deploy a young chap from Japan to shit on your head. In fact, this is true for all MNC, except Singaporean firm who will hire FT to shit on your head instead of promoting you.
Rule#2
if you are a lady, worse...you have no status in the company, relegated to coffee lady...maybe its not shown outwardly but definitely telling during appraisal.
Rule #3
they have strict rules & protocol...eg: all will sit at a long table, no cubicle no screens...so if you wanna surf sammyboy during office hours, think twice.
Rule #4
If you lucky in position to entertain clients, ho say liao..my fren in private banking, sibeh ho...every friday go cheong japanese KTV with boss...n you noe...Japanese KTV are the cream of cream...best part, company pick up tab....
