Maybe at this point a short #Kavanaugh appointment thread would be helpful. So: where are we and what does it mean? What are the Americans doing? Is this just a terrible version of House of Cards?
Justices of the Supreme Court are nominated by the US President and appointed by the President “with the advice and consent” of the Senate. Art. II Sec. 2 of the Constitution. 
The President vets candidates before nomination, discusses candidates with allies, there’s also an FBI background check. Once nominated, the confirmation hearings are held in the Senat Judiciary Committee.
In modern times the hearings involve an interview of the candidate. @BeschlossDC had a picture of Felix Frankfurter saying he was the first candidate to be interviewed. Wikipedia claims it was Harlan Fisk Stone.
@BeschlossDC The Committee then votes to move the nomination to the whole Senate, which votes on a majority (in the past you could filibuster to require a supermajority)
