Internship visas ? paid or non paid?

Iv been looking into getting a work visa for Taiwan…but since i’m not a native English speaker,(Holland) nor do I possess a college or uni degree.
So I have been looking into internship visas…but I can hardly find any information regarding this.

Since I saw a job being posted as intern at the Sun World Dynasty hotel, that pays 15.000 a month.
But I read the there are ‘Tourist visas for internships’ but for as far as I know tourist visas do not allow work.

How does this all work? im so confused right now.
Since they hire people who are still studying how do they go about hiring them? and possibly on what visa?
