How about being an elevator maintenance engineer after college? What's the difference between Schindler and maintenance man? What is the future? What is the working environment like?

The on-site maintenance engineer of escalator is a normal maintenance worker of elevator, and the total salary is generally between 1800-3500.

The main job of on-site technical engineer of escalator is to provide technical guidance for on-site maintenance personnel. The salary is higher than that of maintenance personnel.

The technical level of escalator maintenance and reconstruction engineers is higher than the above two, and their wages are much higher.

The professionalism of administrative management is not as high as the technical salary.

Maintenance and sales engineers will get a commission as long as they have sales, and there will be a sales commission in addition to the basic salary.

This is just my view on the development of elevator industry. I wonder if I can help you choose.
