I would not treat Keep in Touch like a job, award, or formal credential on your resume. Its main value is the relationship and future recruiting opportunity, not the label itself.

Keep in Touch signals continued interest from McKinsey, but listing it publicly can overstate what the program represents. Your resume should prioritize achievements and experiences that demonstrate your capabilities.

If the program gives you access to events or development activities, those experiences may become useful talking points later. That is different from adding 'McKinsey Keep in Touch' next to work experience or education.

Use the program as intended: stay engaged, attend relevant activities, and respond to recruiting outreach. Keep your resume focused on substantive experience unless McKinsey specifically advises otherwise.

I would not put Keep in Touch next to jobs on LinkedIn.

Use the access and relationships. The label itself isn't really the achievement.
