It's an interesting question, because the answers can be at completely opposite ends of the spectrum. Some people join because they have an interest—for example, a Red Seal cook might want to be a naval cook. On the other hand, we have people who join the navy and do not want to do what they do in their civilian careers. They specifically want a different job and work experience through the navy that isn't what they do in the rest of their lives.
