Solve is the McKinsey online assessment, and it mixes two or three game modules: Red Rock, Sea Wolf, and sometimes the Sustainable Futures Lab. Practice each one free with worked feedback, no account needed.
| Module | What you do | Skills tested |
|---|---|---|
| Red Rock Study | Read a briefing and two exhibits, keep a research journal, commit to one calculated number | Data interpretation, case math, signal-from-noise |
| Sea Wolf | Filter eight microbes against hard site rules, then optimize a three-microbe treatment | Constraint matching, set-level arithmetic, structured elimination |
| Sustainable Futures Lab | Rank five initiatives against stated criteria, then handle the stakeholder pushback | Prioritization, judgment under ambiguity, criteria discipline |
Module mixes are candidate-reported and vary by office; a ~65-minute invitation commonly means Red Rock + Sea Wolf, while ~85 minutes often adds SFL. Your invitation is the authority.
