After staying there for more than three years, I can't say that I know all the information, but I can basically be considered comprehensive.
Let's talk about salary first. It's totally personal. You talked very well when you joined the company. Even if your performance is average in the next few years, your income will be guaranteed on a good basis (starting salary). You didn't have the guts to ask for it when you joined the company, or you didn't insist. Then, no matter how well you perform after entering the company, you should also work hard on that basis. Also, Johnson & Johnson generally pays the average market price, so don't expect too much. Besides, someone can always speak higher. In order to control the cost, you are not easy to talk. Naturally, it is below the average price.
Besides, the company atmosphere is basically infighting. People who work honestly have no chance to get ahead, but they often take the blame. After a long time, the rest will lose their enthusiasm and just muddle along. The conspirators can go up, continue to fight after going up, and instigate their subordinates to fight, so as to show the traditional leadership of China: there is no unity below, but you can sit firmly above. For example, the factory director W is a typical person who is afraid to build trust with each other every day. There was a formidable person before, and ZH(ZH's fighting level is far less than W's, but his professional ability is outstanding) can balance him. ZH has left recently, and it will only get darker and darker.
Finally, personal development. Don't waste time if you want to develop. Originally, a big company had a fine division of labor, and everyone could only make their own small pieces. Plus, you have to spend your energy on infighting (if you don't want to fight, others will fight you, and it takes time to guard against it everywhere). As long as you can do well, you don't have time to learn more. The so-called training is quite a lot, but basically it allows you to read documents online, which is seriously divorced from reality. The chances of promotion are slim, and basically no one is trained. When there is a vacancy, they will recruit from outside.
