After-sales are mainly installation, training, maintenance and service marketing. The salaries of the above companies are similar, but Mindray's salary (salary) may be higher and a little tired, but the food subsidies for accommodation and business trips are not as good as those of foreign companies. In addition, the foreign company is home office, that is, working from home, and going on a business trip if something happens. Mindray needs to keep up with customers at all times (even if there is nothing wrong with other people's machines, you need to take the initiative to visit and establish contact) and tap the demand, that is, you are both an engineer and a salesman.
If you have a family, or want to be comfortable and enter a foreign company, this is life; If you want to hone yourself, entering Mindray is a good choice. This is a career.
