PartnerRoundMcKinsey Solve, BCG Casey and Bain SOVA practice simulations
Digital assessments now screen out a large share of candidates before anyone reads a CV. These are working simulations (not screenshots and not a written description) built with the same constraint and scoring logic the real tasks use.
TL;DR
- 6 simulations, all free for now with unlimited runs, playable in your browser with no download.
- Four cover McKinsey Solve (Red Rock, Sea Wolf, the Sustainable Futures Lab and Ecosystem Building), one the BCG Casey online case and one the Bain SOVA test.
- Each runs full screen on the real clock, enforces the real rules, and ends with a scored review of every answer.

Study a 21-species guidebook, switch on four of seven monitors and compare six survey sites on a map of the Tarnmoor Plateau, then place three producers and five animals at one site. Your ecosystem is run through the eating rules turn by turn and scored on how many species survive against the best possible, and on how you investigated.

Three polluted sites, worked in order. At each one, categorise ten microbes against the site's ranges and traits, routing some ahead on a single clue about the next site. Then add four prospects from a reserve and average three microbes into a treatment that has to land inside every range. The best treatments lean on microbes that fail a range on their own.

McKinsey SolveFree35 minProduct + process
A study and its exhibits, with highlighted figures to drag into a research journal. Answer the analysis from the journal alone, build the report's chart and recommendation from your own answers, then work three short cases on the same 35-minute clock. Every figure is true and half of them change nothing.

McKinsey SolveFree20 minFour competencies
Join a five-person team on a five-year mission to bring a polluted, flood-prone river back to health. Rank actions against the board's brief, choose how to answer teammates, farmers, residents and a water company, and adapt as new briefings change the picture. Every decision is scored on one of four competencies and reviewed at the end.

BCG Online CaseFree20 minPer question
A complete case through a chat interface: structuring, maths, exhibit reading, hypotheses and synthesis. Each answer is typed against its own clock and scored on its own rubric.

Bain Online TestFree35 minAccuracy + speed
The four parts most candidates report from the SOVA test some Bain offices send: numerical reasoning from exhibits, logical sequences and deductions, true, false or cannot say passages, and situational judgement. Scored on accuracy and on pace, which reports say the real test weighs too.

A note on what these are
PartnerRound is independent. These simulations are built from publicly described formats so you can practise the underlying skills. They are not the firms' own assessments, they are not licensed from them, and no firm endorses them.
The scenarios differ from the ones you will sit. That is deliberate: the transferable thing is the method, not the content, and memorising a specific ecosystem would not help you.
