The exact Solve experience can vary by current assessment configuration, so use the timing shown in your invitation as the source of truth.

McKinsey has changed Solve games and formats over time, which is why older prep discussions can quote different durations.

Plan your environment around the full testing window, not only the nominal gameplay time, so setup or instructions do not create pressure.

Read the current invitation carefully and practice the format you are actually expecting to receive.

A strong application does not mean you can ignore the online test.

For what it's worth, I overfocused on the assessment and then had almost no time left for cases.
