McKinsey does not always send the detailed Solve score automatically. Candidates who receive it often request it from the recruiting contact associated with the assessment.

If you want the score for your own reference, wait until the assessment has been processed and send a short email asking whether they can share your Solve score and decile. Around a week after completion is a reasonable point to ask if there has been no communication.

The score is useful context, but it does not change the application by itself. Treat it as one data point rather than something you need before continuing to prepare. If useful, this guide on McKinsey Solve guide gives more detail.

I never got mine automatically either. people seem to email recruiting for it.

I'd wait around a week then ask. no harm if you're curious.

score is mostly just nice to know tbh.
