Even though you provided your resume to the Cisco interviewer, they may ask you questions about your experience. You should never assume that the interviewer has read your complete resume. Additionally, they may have read the resume but want to investigate your experience in more detail or explore your experience in areas not listed on the resume. Therefore, it is advisable to bring a copy of your resume, which you can reference in the interview. You should also bring additional copies in case the people you are interviewing with have not seen your resume or did not bring it with them to the interview. Don't become frustrated if they ask you questions that are already answered on the resume. Provide an answer to these questions as you would to any others.
