An old-age company; in the headquarters division where I work, more than 60% of the employees are probably over 50. It used to make a lot of money and once paid a year-end bonus equivalent to 10 months' salary. Things aren't as good now, but it is still an oligopolistic business, so you can still receive a bonus equivalent to five months' salary (though it will be slightly less than your monthly salary each month).

There are actually many drawbacks. The common problem with large companies is that there are too many foolish things. The general manager only gives targets, without any strategy; you have to figure out the approach yourself. As long as the results are visible, that's all that matters. However, the people below usually find ways to embellish the results that the general manager will see—unless the results are too poor. In the elevator industry, I currently can't think of how disruptive innovation could happen. But if disruptive innovation really did emerge, this company might be in considerable danger.
