신생기업에 취직하는 것의 장점은 무엇인가요? 라는 질문에

저는

Most of all, we can learn various work

when I was new employee, I worked at a strat-up IT company
so, I could learn a lot of work from coworker
whenever I don't know how to handle hard work, he gave me useful skill and solution

as a result, i was able to enter large cooperation and i still keep in touch with them

이렇게 만들었는데

질문1.
Most of all, we can learn various work
여기에서 work를 업무라고 쓰인다면 various, a lot of 중 뭐를 써야하나요?

질문2. 이유 2가지가 생각이 안나서 하나를 설명하고 부가적인 저의 예시설명을 이렇게 해도 괜찮을까요?
