Yes, through in Germanys political field the far right and far left are in some points very similar in practice especially just before Hitler came into power. At least iff you take a close look. This is why some people say in paractice the political spectrum is more like a circle with a small gap opposite of "center" and the far left/right being each side of the gap. Positions who are fully opposites are clearly right/left but not extremely right left positions, I guess (e.g. non-radical conservatives with non-radical socialists). But then in the end the left/right analogy just falls apart at some point (at least for any non de-facto binary political system).
Anyway this is why Nazis while mainly being far right managed to gather supporters from the far left. And especially in the beginning there where decision done which looked quite socialist, through in retrospective where basically always ware preparations.
I would say saying Nazis where socialists is quite wrong, but that doesn't mean there wasn't a bit of socialism their politics eve if just for pretentious reasons.
Through it also should be noted that the current political spectrum differs quite a bit from back then, neo-nazies normally have very clearly nothing to do with socialist and the far left has not many people which are extreme socialists but also nationalist either as far as I know.
