Numerical reasoning (Aon Scales Numerical)
37 questions · 12 minutes (under 20 seconds per question)
What it tests. Rapid data location, selective attention and basic financial arithmetic (percentages, ratios, currency conversion to and from GBP).
Worked example. Verify a statement such as 'The Asia-Pacific operating margin exceeded the European margin in Year 3' by locating the right tab and computing, rather than reading all six tabs first.
Common traps. The all-data trap (reading all six tabs before the first question), and confusing a statement that is likely true in the real world with one mathematically verified by the tabs; if the data does not prove it, the answer is Cannot Say.
How to handle it. Scan only the tab titles for the first 10 seconds, read the statement first, identify the key noun, click straight to that tab, and guess and move on if a calculation exceeds 25 seconds.
Verbal reasoning (Aon Scales Verbal)
49 questions · 12 minutes (roughly 15 seconds per question)
What it tests. Verbal scanning, deductive logic and semantic precision.
Worked example. If a text says 'BNP Paribas expanded its green bond issuance in 2025' and the statement claims it 'was the largest issuer of green bonds in Europe in 2025', the answer is Cannot Say: the text confirms expansion, not dominance.
Common traps. Inferring meaning beyond the text and importing outside knowledge.
How to handle it. Treat it as keyword matching: read the statement, pick the most specific noun, find the tab with that topic and cross-reference. Scan for synonyms; you cannot read every passage.
Deductive logic (Aon switchChallenge)
12 to 20 rapidly changing tasks · 6 minutes
What it tests. Deductive processing, working memory and cognitive flexibility under escalating complexity.
Worked example. With operator 2413, the symbol that was 2nd goes to 1st, the 4th to 2nd, the 1st to 3rd and the 3rd to 4th. Harder levels stack two funnels or give the output and ask for the missing code.
Common traps. Overthinking early levels and freezing on double operators by trying to track all four symbols at once.
How to handle it. Track just one or two symbols through the funnel to eliminate options instantly, and keep a scratchpad for double-funnel intermediate orders.
Situational judgement (Aon chatAssess)
Scenario-based · Approximately 20-30 minutes total
What it tests. Alignment with BNP Paribas values, commercial awareness, professional communication and task prioritisation.
Worked example. When a conflict arises, the strongest option prioritises the client outcome without breaking compliance and keeps your manager informed with a proposed solution.
Common traps. Choosing the hero option (staying up 48 hours alone) or the whistleblower option unnecessarily; both read as poor risk management.
How to handle it. Answer as a regulated finance professional: respect compliance, client confidentiality and team cohesion over short-term individual heroics.
