Business in Mexico City relies heavily on personal relationships, extended lunches, and a formal hierarchy. Expect meetings to start with 15-20 minutes of social small talk before any professional matters are discussed.

Master the greeting. Always use professional titles (Licenciado/a for college grads, Ingeniero/a for engineers) followed by the surname until invited to use first names. A firm handshake is expected, but wait for the other person to initiate if you are unsure.
Respect the 'Sobre-mesa'. If invited to a business lunch, never rush to the point. The meal will last 2-3 hours; the 'sobre-mesa' (post-meal conversation) is often where the real decision-making happens.
Dress formally. Mexico City is a formal business environment. Wear a dark suit and polished shoes. Appearances matter; grooming should be immaculate to show respect for your counterpart.
Manage time expectations. While you should always be on time, realize that your counterparts may be 15-20 minutes late due to the city's notorious traffic. Have a book or email to catch up on, and do not show visible frustration.
