Avoid at all costs the Operational departments!
Pros
Location, brand recognition and excellent benefits and few good people. Administration part of the building is place to really work and advance.
Cons
One of the worst place I worked for. Low pay and no advancement for growth. Management style: welcome gossips, finger pointings, favoritism and putting employees against each other instead of managing situations. No support at all. Lots of junk-food parties run by coupe of clerks who are busy most of the time with badmouthing and spreading endless gossips. Old staff with extremely outdated skills (don't know even basic math), not willing to learn anything new for decades get angry to new employees with advanced knowledge or technical skills. Smart and intelligent people are treats for those runner-ups and they will constantly complain to managers either about your attitude or work until they make you run (otherwise they can't keep their jobs for decades). Without Japanese staff this place will go to hell. If you want advancement, good pay or learn new skills STAY AWAY from those departments!
