Questions & Answers about Он работает в компании в качестве ассистента.
What is the difference between saying в качестве ассистента and как ассистент?
Both mean 'as an assistant.' However, в качестве literally means 'in the capacity of' and sounds a bit more formal or official. It perfectly matches a professional or corporate context like working в компании.
Why is ассистента in the Genitive case? Is it because it is an animate noun?
It is in the Genitive case solely because of the phrase в качестве. This phrase always forces the following noun into the Genitive case, regardless of whether it is animate or inanimate, because it translates literally as 'in the quality OF'.
If I rewrote this sentence using как, what case would the word for assistant take?
It would be in the Nominative case: Он работает как ассистент. When using как to express a role, the noun simply matches the case of the person or thing it refers to. Here, it refers to the subject Он, which is in the Nominative case.
We say 'at the company' in English. Why does Russian use в (в компании) instead of на here?
While Russian uses на for broad activities or concepts like на работе (at work), it uses в for structured organizations or physical buildings. Therefore, you say в компании (at/in a company) just like you would say в офисе (in the office).
