If there is no urgent deadline, give the referrer a few business days before sending one concise follow-up.

If the application deadline is approaching, include the exact date so they understand why you are checking. Do not create fake urgency or send repeated daily reminders.

Keep the message practical: thank them again, mention the deadline and ask whether they need anything else from you to submit the referral.

If you still do not hear back and the deadline is close, submit the application through the required channel rather than missing it. A referral can help, but it is usually not worth sacrificing the application itself. For more detail, see the consulting coffee chat guide.

I followed up after four business days and included the deadline. They had simply forgotten.

I would submit on time rather than wait indefinitely for the referral.

I had something similar and the useful part was clarifying the exact recruiting rule instead of relying on what classmates had heard. In my case, the exact timing around how long should i wait before following up with an mba consulting referrer mattered most.

The MBA process moves fast, so I would rather get one direct answer from recruiting than build a plan around assumptions. In my case, the exact timing around how long should i wait before following up with an mba consulting referrer mattered most.

I found that second-years who had just gone through the same process gave much better context than generic online advice. In my case, the exact timing around how long should i wait before following up with an mba consulting referrer mattered most.
