Why are you applying for a job that you didn't major in?
Why didn't you pursue a career in your major?"
In the United States the statistics for a person changing career paths is very high. It's something like an average person will change careers five times. Changing jobs is one thing, but completely changing careers is a big move. So this question is not that significant. If everyone worked in the industry as their major, then this question is more important, but because everyone changes jobs frequently, it's no big deal. You just have to use this opportunity to show them how much you like the current industry you are in.
