I interned in undergrad within a major Japanese automaker's keiretsu (at their global HQ in Japan), and I didn't have an engineering background. That said, most undergrad opportunities still tend to focus on engineering, IT or marketing/sales, and from what I've seen, the MBA opportunities tend to have similar pathways. Of course, there are some MBA pathways that aren't always available to undergrads, such as strategy or finance.
It will also depend on what company we're talking about, as the cultures and locations (and consequently, their hiring patterns) will vary somewhat as well. Some of the import automakers for example, will still dictate corporate strategy mainly from overseas.
