I asked a mechanical engineer in hiring if a double major on a resume made any difference to him. He said that if the major was not related to engineering, he really didn't care about it. They're paying you to be an engineer, nothing more. I studied Russian and in aerospace engineering in the US, employers absolutely did not care about it. I now resent the time/money spent on that coursework, and wish I had taken stats or CS, maybe dabbling in Russian on my own time.
