The difference is small, but mostly as probing questions to interviewers. I take the mind the more you can speak the language the more comfortable people become with you.
Here's something small but I was doing a SQL interview one involved a a card_tx table with the amounts stored in integers values in cents. I immediately noticed this and chatted with the interviewer about this. My assumptions were wrong, and the floating point arithmetic was a simpler reason than what I was thinking.
Anyway you can display you have thought about relevant business problems to where you are interview engineers tend to have a strong reflex to engage the person more.
