The joke is that a black man is even interviewing someone in the first place. The title on his desk says “DEI & Talent”, so some racist probably made this cartoon.
The initial interviewer is usually a woman from HR, most likely white. By the time you get to the Associate or Manager or even a panel interview the person across the table definitely isn’t going to be black, and if the interview is on a panel the black person-likely not even a man, because that’s means the black man was high enough in the organization to be in on the interview and on top of that requested to be in on it, and on top that decided to do it - is either going to agree with the panel who decides to hire someone who’s not black, or be overruled by the other people on the panel who definitely aren’t black.
Best you can hope for is that they don’t care what race you are, or they think they can push you around once they do hire you, so that you don’t make waves and cowtow to whatever the group wants.
