Hire candidates who read the numbers — not just the narrative around them.
Spreadsheet skills and degree grades don't prove someone can think with
numbers.
Use our 15-minute, scenario-based test to see how candidates interpret
data, calculate accurately, and draw sound conclusions - before you commit to interviews
or a hire.
Why Test Numerical Reasoning?
Numerical reasoning underpins decision-making in every data-driven role — from
finance to marketing to operations. It's not about advanced maths; it's about
interpreting numbers correctly and acting on them.
The problem? CVs can't
show you how someone actually works with data. Heroify helps you see it
early.
Without Testing
What you risk
- Decisions based on misinterpreted data or flawed calculations
- Budgets, forecasts, and reports riddled with errors
- Employees who avoid numbers and rely on gut feeling instead
- Missed insights hiding in plain sight within your data
With 
What you gain
- Employees who make confident, data-backed decisions
- Accurate reporting and forecasting you can trust
- People who spot trends and anomalies in numbers quickly
- Fewer costly errors in financial and operational processes
When to test for Numerical Reasoning?
Use this test when the role requires:
- Interpreting charts, tables, or reports to draw conclusions
- Working with budgets, forecasts, or financial data
- Calculating percentages, ratios, or growth rates accurately
- Comparing numerical options to make business decisions
- Spotting errors, trends, or anomalies in datasets
- Translating raw numbers into actionable business insights
Rule of thumb: If the role involves working with numbers regularly — even if it's not a "maths job" — use this test.
Who Should Take This Test?
Numerical Reasoning is critical for any role that requires interpreting data, managing budgets, or making decisions based on quantitative information.

Sales Managers
analysing pipeline, quotas, and revenue projections
Graduate and entry-level roles
where numerical competence is a baseline requirement
What Does The Numerical Reasoning Test Measure?
The Numerical Reasoning test shows how candidates:
Interpret numerical data presented in tables, charts, and real-world formats
Perform accurate calculations under realistic time constraints
Draw valid conclusions from quantitative information
Identify errors, trends, and significant patterns in data
Our methodology is validated by I/O psychologists and based on decades of research into cognitive assessment. Each question is designed to reveal how candidates think, not just what they know.
How It Works
We don't use abstract maths problems or school-style equations.
Our
test presents realistic business scenarios requiring candidates to interpret data,
perform calculations, and draw conclusions from numbers - just like they would on the
job.
-
Takes 10-15 minutes, not half an hour
-
Realistic work-like scenarios
-
Balanced difficulty that actually differentiates candidates
-
Scientifically validated
-
Mobile-friendly, candidates can take it anywhere
-
Benchmarking results against real candidates in similar roles
-
Cheat-resistant signals based on behaviour patterns, e.g. unusual speed or tab-switching
-
Candidates don't feel "examined". They feel challenged — in a good way
A company's Q1 revenue was £2.4M, Q2 was £2.76M, and Q3 was £3.17M. If the quarter-on-quarter growth rate remains consistent, what is the closest estimate for Q4 revenue?
