I can't say that I have seen any party documents floating around, but I'll take your word for it here. A person having those views or beliefs still isn't a crime, acting on them is.
A person in a workplace can have whatever views they want. Holding a view in no way prevents them from being able to do the work well. Its a different story if they cause a problem at work, but that is viewpoint agnostic - anyone starting political fights or worse at work is a problem.
A person is entitled to hold any political views they wish, and a business is entitled to not hire them for those views. Just like freedom of speech does not entitle you to a platform or give you immunity from the consequences of saying things.

There are quite literally millions of well recorded documents, pictures, movies, personal accounts of affected people available about what Nazism did and does. If you do need a place to start, feel free give the Wikipedia article a read and use the underlying sources to learn more.
The Nazi Party no longer exists and you're linking to ideology in Germany at the time. We could similarly link to pretty terrible political party views of Republicans or Democrats over our history.
By no means am I defending Nazism here, I would take huge personal issue with any holding those views. That's entirely separate from the topic here though, and I don't agree with discriminating hiring processes based on political views regardless of what they are. If someone can go to work, get the job done, and be a net-positive member of the team I have no reason to act against them.
Not hiring people only for personal views they hold is just a weirs bar to set. Judge people by their fit for the role and their actions. Attempting to both uncover and judge a person's beliefs is a losing battle at best.
It is not a weird bar at all when the "personal view" here is being a Nazi. The action of believing in Nazism is actually a disbarring for any role of trust, integrity, or value in our society.
Being a Nazi is not a protected status (yet) and you should expect to be fired immediately if you espoused those views anywhere, at all.
