I work at another BigCorp and am involved with interviews. There are a ton of languages I just don't know enough of to interview you in, but a popular functional language (python) plus a choice of a structural language (c/c++ or java) covers a large range of candidates. If the only language you're comfortable in is Scala or Go and you really are uncomfortable with C , python and java, clearly you must realize a lot of the industry will have trouble hiring you.
You also must realize that I don't actually use much python, c, or java. Those are just languages I can generally expect candidates to be comfortable with.
