First of all, the treatment: on average, the best companies would be the three GE, Philips, Siemens, and then other foreign companies, Myriad, Unimicron, Anchor, etc., and lastly, some of the lesser-known companies.
So, the Shimadzu you mentioned should belong to the second tier, but it is an outsourcing company, which is what we call the third party, they can't compare their salary and welfare protection with the A-side company, so the salary should not be very high, and it is considered as a middle-income in the local area, right?
Secondly, career prospects: in general, the company recruits, usually from the third-party company into the people, so the career prospects can be, if you follow the right product line, but also very likely to enter the three major previously mentioned, so your income will be greatly increased; after-sales service technology content than the research and development of low, but definitely higher than the automotive sales, because the after-sales service is half of the technical and half of the business of the work! You must be able to repair the machine, but also must be able to deal with customers, for example, a machine due to quality problems broken, a poor engineer to repair may be a scolding, but an engineer who will deal with interpersonal relations to go may be a good cigarettes and wine. At the same time, people are always going to be sick, check the patient's machine is always going to break down, so don't worry about not having a career. Generally will follow the engineer-technical support engineer-area supervisor-manager so development, you can also by changing jobs in sales and other careers.
Then, business trips: very frequent. I used to be in one of the three major, travel frequency of 150/365, our third party is mainly responsible for the third and fourth-tier cities, it can be said that the hard work of business travel will exceed the three major, which, you should have a full understanding of, do not eat this bitter.
Lastly, the threshold: I graduated with a master's degree to do after-sales, and I came in with a few colleagues, two 985 masters, a 211 masters, you say the threshold is low? I think just graduated don't count what, mainly still determine the life development path and learn something. If you like traveling, and at the same time like to deal with people, I think after-sales service is a good career.
