What question types are on the Bain TestGorilla test?

Numerical reasoning

Short calculations from a small table. Our practice shows the working. Example: a $60 fee is split by 3 teams, and each team also buys 10 metres at $5. One team pays 60 / 3 = 20, plus 10 x 5 = 50, so $70.

Working with data

Counts in a grid where you pick the right group before dividing. Example: Region A renewed 120 of 400 customers and Region B renewed 90 of 250. A is 120 / 400 = 30%, B is 90 / 250 = 36%, so B is higher even though A renewed more people.

Critical thinking

Separating what must follow from what only could be true. Our practice has two.

Case evidence

Choosing the fact that best supports a business decision. Our practice has one.

How is the Bain TestGorilla test scored?

Bain publishes no pass mark or weighting and says the result is one part of the review. Bain's Seoul document says results are not shared with candidates, and TestGorilla says the employer chooses whether you see them. TestGorilla says wrong answers carry no penalty but skipped ones score nothing. Cutoffs quoted online are not from Bain.

Which Bain test will I take?

Bain says that if an assessment is required, an email after you apply names Sova or TestGorilla, and requirements vary by role and office. Read it for the provider, deadline and camera rules. Bain says Sova, unlike TestGorilla, does not need one sitting.

How should I prepare for the Bain TestGorilla test?

  1. 1 week before. Read your invitation and TestGorilla's candidate guide.
  2. 5 days before. Practise numerical and data questions, writing the formula before using the calculator.
  3. 3 days before. Run a timed set where you never skip, and review each wrong answer.
  4. 1 day before. Stop new practice and test your browser, connection and any camera.

What mistakes cost the most?

Leaving a question blank. TestGorilla says it counts as wrong and cannot be reopened.

Wrong denominator. Data questions often ask for a share of one group, not of everyone.

Splitting the sitting. Bain asks for one sitting, and TestGorilla says the timer keeps running if you close the window.

Trusting a section list. Neither Bain page publishes one.

What should I do the day before?

  • Find the invitation and note the deadline.
  • Charge your laptop and unplug any second screen.
  • Put pen, paper and a calculator next to you.
  • Pick a quiet slot long enough to finish.
