Both dreams seems to reflect your feelings about your recent job interviews. You are ready to get going in your new job, but the interview process feels like you are back in school with a professor (the interviewer?) who is still assessing his research (the charts and graphs.) Your dream seems to reflect your discontent with his process (charts and graphs), because on some level, you feel that he may be considering the wrong data (other candidates?) On some level, do you feel that the interviewer got the wrong impression about you and/or your experience/qualifications? The dream would be a logical playing out of your feelings given the fact that you hadn't yet heard from them.
Your second dream reflects your better, more spiritual feeling that you did fine in the interview. It's logical for your feelings (and thus dreams) to go back and forth when you just don't know.
Please let us know what happened. Hope you get it. Good luck!
