Treat Keep in Touch as a positive relationship signal, but not as an offer or guaranteed interview.
The useful move is to stay genuinely connected, keep building your profile, and understand what the McKinsey Keep in Touch program is designed to do.
If McKinsey sends events or check-ins, engage naturally. You do not need to email every month just to remind them you exist. A meaningful update such as a new internship, role, degree milestone, or recruiting cycle is a better reason to reconnect.
