Sure, the hiring manager has digital copies of your résumé and cover letter. But make life easy for him or her and bring a few hard copies with you.
Amanda Augustine, the career advice expert for TopResume, previously told Business Insider that you should bring one copy of your résumé for every person you'll be meeting with, plus a few extra.
"You'll need one for you to reference while you talk, and one copy for each interviewer, just in case they aren't prepared," Augustine said.
You may also want to bring a pen and paper to take notes during the interview — or to work out tough problems if you're interviewing in consulting, finance, or engineering.
