New McKinsey Solve Game: 2025 Sea Wolf Update

Welcome to the most comprehensive walkthrough of the Sea Wolf game, the newest addition to the McKinsey Solve Game (Problem Solving Game) in 2025.

In this video, we walk you through the full gameplay using Prepmatter’s interactive simulation. The Sea Wolf game (Ocean Treatment or Ocean Cleanup) challenges candidates to select and evaluate microbes to clean up contaminated sites. We’ll guide you step by step as you solve the game alongside us.

New: If your score is below the top quartile (75%) and McKinsey cites your Solve performance as a reason for rejection, you’re eligible for a 50% refund. Just submit the official email from McKinsey within 60 days of purchase.

At 15:41, you said there's no need to worry about having an equal distribution between sites. However, I still don't understand why, during the second phase of choosing microbes, you prioritized keeping the two microbes from 18:10-18:55 in Site 1 rather than moving them to Site 2. You explained that the rationale was that they met 2 out of 4 requirements. But since we’ll be selecting more microbes for the prospect pool later on, why not take the chance and move them to Site 2, given that they have the desired trait?

To put it differently, I’m also wondering: why are we keeping microbes that only meet 2 out of 4 requirements, instead of raising the bar to 3 out of 4?

At 08:02, how is Aprofilum's Permeability within Site 1's range? The former has a Permeability of 9 while Site 1 has a range of 2-4!

At 09:48, Under submitted microbes why is the efficiency score 0% for attributes Mobility and energy? The average falls in the given range right?

Allocate 10 minutes to each, and be fast - time flies. Not as easy as it looks, just get as much practice in as you can.

I recently did this in the McKinsey Solve test, however, there were no perfect averages for the charactersitics (only 2/3). Did I do something wrong in the selection process or was this just a test in choosing a solution from imperfect data?

[amandaphasha]

where is the required range of 24-30, 24-30 and 12-18 coming from?

Is there no link between the microbes you choose to keep in the current pool in the initial selection and the 6 microbes shown in the pool in the next stage? If there is a link, how do they randomly generate the 6 out of the 8 that you chose to keep?

Is the MIC and Camera turned on during the Test ?

At 25:15, how did you arrive at the ranges of 7-13, 5-11 and 2-8?

How did you get the range 24-30 and 12-18?
