Psychometric Test Investment Banking: UK Guide to Numerical, Verbal and SJT Prep

Here is the part that catches out strong candidates every cycle: a well-built CV, a genuinely good motivation paragraph, and then a rejection email that arrives before anyone has read either one properly. That is what a numerical reasoning test does when you sit it cold. For large UK programmes, thousands of applicants are filtered on a handful of timed questions before a human ever opens the application form, and most of those rejections are not caused by weak candidates. They are caused by candidates who never practised extracting a number from a dense chart under a countdown clock.

Treating psychometrics as an annoying formality is the single most common way to lose a strong application. Each test type is measuring something specific, and once you know what a bank is actually checking for, the prep gets a lot more targeted than grinding through random question banks.

Where psychometric tests sit in the UK banking pipeline

Typical order after online application:

1. CV and application form screen (often automated or semi-automated)
2. Psychometric tests (numerical, verbal, sometimes SJT or personality)
3. Video interview / HireVue or first-round phone screen
4. Assessment centre or superday

Tests usually arrive within days of applying. Deadlines are often 48 to 72 hours. If you are applying to multiple banks on rolling deadlines, prep tests before portals open, not after you click submit.

Coordinate timing with our finance internship deadlines rolling guide so you are not sitting three different test batteries in one evening.

Numerical reasoning: what banks actually test

Numerical reasoning is the highest-stakes test for most finance applicants. You typically receive charts, tables, or short passages and answer multiple-choice questions under time pressure. The question types repeat across providers even when the numbers change: percentage change (revenue grew from £120m to £138m, what is the growth rate?), ratio interpretation (given EV/EBITDA across peers, which looks expensive on headline multiples?), currency or unit conversion across regions reporting in different currencies, and break-even or margin questions (if margin falls 200 basis points on fixed costs, what happens to profit?).

None of these require anything beyond GCSE-level arithmetic. What makes them hard is doing that arithmetic accurately while a clock runs and a table has three more columns than you need.

What assessors measure

• Can you extract the right number from a dense table?
• Can you perform basic arithmetic quickly without a calculator (rules vary: some tests allow on-screen calculator)?
• Do you sanity-check answers before moving on?

Prep approach (three sessions)

Session 1: Untimed practice. Focus on reading charts correctly. Mark where you misread axes or units.

Session 2: Timed sets. Accept leaving one question blank if it saves three careless errors elsewhere.

Session 3: Mixed difficulty under exam conditions. No phone, no music, same device you will use on test day.

Mental math shortcuts help: memorise common fractions (1/8 = 12.5%), practise doubling/halving chains, and round aggressively when answers are far apart.

Verbal reasoning: the underestimated filter

Verbal tests present short passages with statements marked true, false, or cannot say. They feel easier than numerical tests. Strong candidates still fail by ** importing outside knowledge** or rushing inference.

Rules that matter:

• True only if the statement is explicitly supported by the text
• False only if the text contradicts the statement
• Cannot say when the passage is silent, even if you "know" the real-world answer

Finance students often overthink with market knowledge. The test measures reading discipline, not commercial awareness. Save macro views for interviews; use our commercial awareness finance interview guide after you pass the gate.

Verbal prep drill

Read one passage per day. For each statement, underline the exact sentence that proves or disproves it. If you cannot underline, the answer is probably cannot say.

Situational judgement tests (SJT)

SJTs describe workplace scenarios and ask you to rank responses or pick the best and worst option. Banks use them to proxy ** judgement, teamwork, and client awareness** before interviews.

There is rarely one objectively "correct" answer. Providers score against a competency profile the bank wants (collaboration, integrity, commercial awareness, escalation).

Principles that usually score well:

Do not try to reverse-engineer the "bank personality." Extreme answers in either direction (too passive, too aggressive) fail. Consistency matters across scenarios.

Personality and style questionnaires

Some programmes add personality or work-style inventories. These are often not timed and look low stakes. Treat them seriously.

Guidance:

• Answer consistently, not aspirationally
• Avoid picking every "leadership" option if that is not how you behave
• Do not select contradictory extremes across similar questions
• If honest answers suggest poor fit, that may be useful information before you commit to a path

You cannot "win" a personality test with a fake persona. Inconsistency flags are common.

Retests at assessment centres

UK assessment centre formats sometimes include supervised retakes of numerical or verbal tests. Reasons include verifying online scores and comparing candidates under identical conditions.

Implications:

• Your home score should be reproducible, not a one-off with hints from forums
• Practise without notes, without pausing, on a laptop similar to test conditions
• Sleep and hydration matter on AC day as much as interview polish

If you pass online tests barely, assume retest day is where borderline scores get confirmed or rejected.

Provider formats and practical logistics

Banks use different vendors and interfaces. Before starting:

• Check calculator rules (on-screen only vs none)
• Confirm deadline timezone (UK vs US headquarters)
• Use stable internet; wired connection beats coffee shop Wi-Fi
• Complete tests in one sitting when possible; some systems allow pauses, many do not

Bank-specific application guides (e.g. Barclays, Citi, UBS) note blended assessment steps. Read the one for your target firm so test order does not surprise you.

Common mistakes that fail strong candidates

How psychometrics connect to later stages

Passing tests does not replace interview prep. It unlocks the stages where differentiation happens: HireVue, phone screens, group exercises, and case studies.

Use HireVue finance interview tips once video stages open. Use group exercise assessment centre prep and e-tray exercise finance guides when AC invites arrive.

Two-week prep schedule (if applications are open now)

Adjust if you already have live test invites: deadline beats schedule.

Track tests per application

Each bank may use different providers, deadlines, and retest rules. Tracking which stage you are at prevents missed windows and duplicate panic prep.

Complete one untimed numerical set and log every misread before you submit your next application, and only open portals when you can sit tests within 48 hours.
