When preparing for an in-person panel interview, what specific quantity of resumes should be brought regarding the panelists?

One copy for every panelist, plus one for yourself.

Physical preparedness for an in-person panel interview requires accounting for every person sitting at the table, even if materials were submitted digitally beforehand. The established protocol dictates bringing enough copies of your resume to cover the entire group. This means supplying one physical copy for every single panelist present, in addition to having one copy retained for your own quick reference during the discussion. This gesture ensures that everyone, regardless of their primary role (technical, peer, or HR), has immediate access to your professional history, reinforcing preparedness and respect for their time.
