If they are bringing you to work in a position here, they will/should take care for your resident/work visa.
If your company falls under the investment law, it will be light speed and hassle free. You just have to show up for the health examination. Companies in that scheme use to take care of this for their foreign employees.
Otherwise, you will have to do it yourself. Not difficult but time consuming, specially if you don't speak the language. I saw the requirements in english, I think on the Legal forum.
Good luck

Edited to Add: Maybe this can help you get an idea of the requirements:

Costs are not up to date, thats for sure. But you can read the papers involved.
