I took the high-voltage electrician's certificate and wanted to work as an electrician. Which is more suitable, property or factory?

First, you have this certificate to see how much professional knowledge you will have.

I have worked in real estate and also worked in a factory.

Property companies look at the size of the working environment. This certificate is good for property. If the property management company is large, you can manage things that others can't do (with certain skills). If the property management company is small, this certificate is better. But if you want to earn a salary, it's not much higher, but you can learn a lot. Salary depends on the size of the property. Talk to your boss about your technical work experience.

Factories should also look at large and small factories (with certain skills) with high wages and promising development prospects to learn something.

Small factories don't care about this certificate, as long as they have technical wages, it's easy to talk about it.
