Development prospects is
In these three big inside: CS engineer - TES (technical support engineer) - area manager or transition to do sales, project engineers and so on.
Besides the three big ones: jumping ship to a small company to do after-sales manager; there are a few old colleagues who started their own business to do maintenance, and now they are also earning a lot of money.
Overall, except for frequent business trips (my product line travels about 150 days a year, I quit because of business trips, this should be fully considered), sometimes need to work at night, the other is okay, after all, it is the world's top 500 companies, and everything is guaranteed (commercial medical insurance, personal accident insurance, gasoline subsidies and so on). If you can accept frequent travel and night work, this is a very good job, career prospects are also very bright, after all, there is always a machine will break down.
