A superday usually refers to final round interviews for summer analysts or first year employees at an investment bank, consulting firm, or other financial firm. The day usually consists of anywhere from 3-20 interviews for multiple hours. Many bulge bracket firms will do 3 - 5 half hour interviews back to back with different professionals from the group that you are applying to.
Job or internship offers from superdays can sometimes be given the same day but can also come weeks after the fact.
