How to check the authenticity of a job offer?

I and my friend got a job offer from a company when we sent our CVs to it. Without any face-to-face interviews or questionnaires, they offered us the job and good packages. Still, they have not asked for any money for visa processing or anything.

We are currently working in the UAE and the new job location is in the Netherlands. Without any interview or interactions, how can we accept the job?

How can we check for genuineness?
