While facing an interview always give concentration what your are talking about and mind your local slang in your professional communication. Before delivering any words try to prepare it from earlier twice to thrice. Don't speak a lot unnecessarily, it may distract the way of your speaking.

Modern youth always use their own slang while communicating with their friends and neighbor. Practicing of such words can be turned into habit. So always be alert what you are expressing to the interviewer. Try to give maximum effort to not derail from the professional wording during an interview.

Your slang may not be understood and may create negative impressing in the interviewer mind. So your communication must be formal and explicit as possible.
