The format

What Slaughter and May's psychometric test actually looks like

There is no automated pre-interview online assessment filter. Unlike Linklaters or Freshfields, where submitting a form triggers an immediate Cappfinity or Watson Glaser test before any human reads your file, here every application is read manually first. The 'assessment stage' happens entirely in person at the selection day, not in your browser at home.

Timed sections

Most psychometric tests split into 3-5 sections, each with its own clock. Speed and accuracy both count.

Adaptive difficulty

Modern formats get harder if you answer correctly, easier if you struggle. Your final score reflects what you can actually do under time pressure.

Pass mark

Slaughter and May sets a pass mark per test type. Below it, you don't progress regardless of how strong the rest of your application is.

Completion window. If a short online critical-thinking test is used in a given cycle, sources say it can trigger within around 48 hours of submission. Otherwise, selected candidates are invited directly to the selection day, where the firm's bespoke critical-analysis and written assessments take place.

By division. Uniform across all applicants. The firm does not alter its testing by practice group: every prospective trainee is evaluated on the same core traits of independent thought, written expression and the capacity to defend an argument under pressure.

Recent changes. Sources conflict. One firm-guide source describes a timed online critical-thinking test (a bespoke analytical test or a Watson Glaser variant) after the application. Other detailed sources state the firm has never adopted an automated provider model and runs no online filter at all, deliberately preserving an interview-led framework. Treat the live selection day as the real assessment either way.

The provider

What Slaughter and May actually buys

Slaughter and May configures its own selection of In-house bespoke assessment (no external psychometric provider) modules. Below: the exact products in the suite, why they were chosen, and what the provider's reputation is across the candidate pool.

Modules in the suite

  • 60-minute written case study (commercial dossier to board report)
  • 15-25 minute current-affairs article analysis (live debate prep)
  • Behavioural / situational judgement via the HR interview and trainee tour

History at Slaughter and May. The firm has not switched providers in recent cycles because it has never adopted an automated provider. A separate source notes a Watson Glaser-style critical-thinking test in some cycles, so applicants should prepare critical-reasoning skills regardless.

Candidate reputation. The firm explicitly does not use Watson Glaser (TalentLens), Cappfinity, SHL, Aon/cut-e or Arctic Shores as a standing model, and uses no game-based assessment. It trusts its partners' collective judgement over a third-party psychometric index, prizing individuality and independence of thought.

Section breakdown

What each part of the Slaughter and May assessment tests

Each section has its own format, timer and trap pattern. Worked examples below show exactly what you will see and where candidates drop points.

Critical thinking and verbal reasoning (in-house case study)

One integrated written report · Part of the 60-minute written exercise

What it tests. Identifying assumptions, evaluating competing arguments and drawing valid inferences from dense, un-redacted text, distinguishing fact from executive opinion and speculation.

Worked example. A CFO memo may contradict an external market report on consumer trends; failing to notice and call out conflicting viewpoints signals weak critical analysis.

Common traps. Regurgitating the text by summarising what the documents say rather than evaluating them, and failing to spot inconsistencies between sources.

How to handle it. Read with a sceptical mindset: ask what each director's hidden agenda is and whether a projection is data-led or wishful. Synthesise the facts to highlight risks and opportunities, do not restate them.

Logical, inductive and deductive reasoning (strategic synthesis)

One reasoned recommendation · Part of the 60-minute window

What it tests. Deductive reasoning (applying broad economic principles to the scenario) and inductive reasoning (inferring structural risks from specific trends), with a conclusion that follows logically from the evidence.

Worked example. Choosing a definitive direction early, then structuring the report conclusion-first, supported by data, systematically dismantling the alternatives.

Common traps. Hedging your bets and concluding 'both options are good'; making logical leaps that skip the structural steps; ignoring a glaring counter-argument in the text.

How to handle it. Partners despise intellectual cowardice. Choose a direction early, state your conclusion first, then justify it and address the risks of your chosen path.

Numerical reasoning (embedded financial data)

Embedded in the report · Part of the 60-minute window

What it tests. Quantitative literacy: extracting relevant metrics from a table and interpreting what the numbers mean for the business's strategy.

Worked example. If revenue is rising but net margins are shrinking year on year, you must explicitly flag that as a sign of rising operational costs.

Common traps. Treating the numbers as separate from the narrative; over-compensating by attempting complex modelling or unnecessary ratios that drain your writing window.

How to handle it. Look for the story behind the numbers and cite key percentages or profit figures to ground your recommendation in reality.

Situational judgement and strengths (HR interview and trainee tour)

Conversational · About 30 minutes plus the tour

What it tests. Professional judgement, resilience, collaboration and cultural fit, looking for a rare combination of intellectual self-assurance and genuine humility.

Worked example. Being asked to reflect honestly on the written exercise you just completed; admitting a point you missed and how you would rectify it shows emotional intelligence.

Common traps. The arrogance trap (coming across entitled or aggressive) and the scripted trap (robotic answers lifted from a recruitment brochure).

How to handle it. Treat the trainee tour as part of the holistic assessment; trainees feed back informally. Be curious, respectful and authentic, and reflect honestly in the HR interview.

Current-affairs article analysis (the signature section)

One thesis to summarise and defend · 15 to 25 minutes reading, then a live debate

What it tests. Speed of comprehension, extracting a thesis from an editorial and engaging in unscripted, rigorous debate with two partners.

Worked example. Articles rarely require specialist legal or financial knowledge; they cover themes like the ethics of AI or state intervention in markets, so the test is pure comprehension and argument structure.

Common traps. Fearing the confrontation and staying quiet or instantly agreeing; stubborn blindness that refuses to concede a glaring flaw.

How to handle it. Identify the author's core thesis, supporting arguments and unstated assumptions, form a clear personal view, and when challenged say: 'That is a valid point, and if that holds true it would require me to modify my position as follows...'

Game-based or immersive assessments (the non-existent filter)

None · None

What it tests. Not applicable.

Worked example. The firm views gamified recruitment as an unnecessary abstraction from the real work of a corporate solicitor.

Common traps. Wasting hours practising rapid-clicking games or spatial-memory tests for this firm.

How to handle it. Direct 100% of your energy toward reading and analysing long-form qualitative and quantitative material, such as premium financial journalism.

Pass mark

How Slaughter and May scores the assessment

A holistic, human-led process with no mechanical raw score or percentile threshold. Performance across the written case study, article analysis, partner interview and HR interview is collated into a unified candidate profile.

Competitive percentile thresholds

  • Written case study. Internal qualitative matrix (Pass / Borderline / Fail) on structure, prose, synthesis and commercial pragmatism
  • Article analysis and partner interview. Live partner consensus on comprehension, articulation, agility and resilience under challenge
  • HR interview and tour. HR competency framework on motivation, firm understanding, interpersonal skill and fit

Methodology. Partners and HR aggregate qualitative assessments into a single candidate evaluation. There is no calculation where a high score in one area automatically cancels a poor score in another.

Response time. Candidates typically wait 5 to 14 working days for a final outcome (other sources cite 48 hours to 5 days for the live rounds).

Score visibility. The firm frequently offers constructive, personalised verbal feedback by phone to candidates who reach the final selection day but are unsuccessful.

How to practise

Drill Slaughter and May's exact format

Same provider, same section structure, same time pressure. With a scored report after every test so you can fix the weakest section before the real one.

  • In-house bespoke assessment (no external psychometric provider)-calibrated practice. Not a generic stand-in. The exact provider and section structure Slaughter and May uses on the day.
  • Adaptive question difficulty. Questions get harder when you nail them, easier when you struggle. Walk away knowing where you actually stand.
  • Coaching, not just a score. "You are spending too long on table-data questions" beats "you scored 68%". Specific advice per weak section.
  • Percentile benchmarking. Your score compared to the UK candidate pool, so you know if 70% is excellent or worrying for that test.

Why candidates fail

How candidates lose Slaughter and May's assessment

Specific failure patterns documented across past applicants. Most are avoidable with structured preparation.

  1. 1

    Passive summary in the case study

    Describing the fictional company's history rather than giving an actionable, forward-looking strategic recommendation.

  2. 2

    Intellectual indecisiveness

    Trying to stay neutral when asked to take a side, which signals a lack of confidence and poor commercial judgement.

  3. 3

    Failing the partner challenge

    Folding instantly (no conviction) or becoming defensive and argumentative (hard to work with) when an opinion is questioned.

  4. 4

    Poor time management

    Spending 45 minutes reading the dossier, leaving 15 minutes to write, producing an unfinished report with an abrupt or missing conclusion.

  5. 5

    Missing the distinctive structure

    Treating the firm as identical to Clifford Chance or Linklaters and missing the lockstep model and multi-specialist training.

  6. 6

    Neglecting prose quality

    Typos, run-on sentences or casual language; the firm values flawless English prose, where a single misplaced mark can alter a deal.

What works

What separates the candidates who pass

Concrete habits drilled by candidates who clear the cut-off, drawn from applicant accounts and practice patterns.

  • Immediate executive summary

    Open the report with a clear, three-sentence summary of the strategic decision and the core reason it must be taken.

  • Explicit mapping of risks

    List the top three operational or financial risks of your chosen strategy and outline practical mitigation steps.

  • Active synthesis of conflicting data

    Explicitly note where a manager's internal opinion is undermined by quantitative market data in an appendix.

  • Flawless document structure

    Use clear headings, concise bullet points and short, scannable paragraphs for a busy senior reader.

  • Exceptional listening

    Listen to the exact wording of a partner's question and address the precise point raised rather than delivering a pre-prepared answer.

From past applicants

How recent Slaughter and May candidates approached the assessment

Anonymised candidate accounts of how recent applicants approached the Slaughter and May assessment. Each covers the prep, the experience, and the outcome.

Non-law graduate, direct training contract

Prep. Anxious that a non-law background was a disadvantage with no online psychometrics to level the field.

Experience. A six-page dossier on a consumer-goods company facing supply-chain issues and an overseas acquisition. Spent 20 minutes reading and charting a SWOT, then 40 minutes typing a structured memo with headings referencing the financial appendices. The article was a surprise piece on whether public museums should charge entry; partners attacked the candidate's pro-free-entry view on fiscal-deficit grounds, and the candidate held the position by weighing long-term educational returns against short-term budget pressure.

Outcome. Training contract offer six days later.

Law undergraduate, summer vacation scheme

Prep. Found the day stripped back, with no clicking games or artificial SJT screens.

Experience. Almost ran out of time on the case study after spending too long on a complex market-share graph, forcing a punchy write-up in the final 25 minutes. The partner interview spent 25 minutes on an FT article about tech monopolies, pushing back on every sentence; when a partner pointed out a contradiction, the candidate paused, thanked him and reframed the argument. The HR interview focused on why the candidate preferred the lockstep system to merit-based pay.

Outcome. The process felt rigorous but fundamentally fair.

Practice strategy

Where to drill the Slaughter and May format

Mirror the firm's qualitative methodology. Automated multiple-choice practice offers diminishing returns here.

  • High-yield reading routine

    Read one complex opinion piece daily from the FT (Lex or the Big Read), The Economist or The Times. Run a 15-minute timed drill, then extract the thesis in under 20 words, the three supporting pillars, two unstated assumptions and a counter-argument.

  • Case study simulation

    Use strategy-consulting case materials (basic McKinsey or BCG cases) or written exercises from other elite firms. Practise turning a messy 5-page scenario into a structured, grammatically flawless 600-800 word memo within 60 minutes on an unfamiliar keyboard.

  • Free practice on Intervyo

    Drill timed written-analysis and commercial-awareness exercises in realistic formats to calibrate before the live day.

Time investment. Plan 15 to 20 hours of focused preparation over the three weeks before your assessment day, split between commercial awareness and live written and verbal argument synthesis.

Time management

Five moves that protect your score

  1. 01Set your own clock per question. Divide section time by question count. Move on when you hit your per-question budget, even if you are mid-thought.
  2. 02Read the question before the chart. Half the work in numerical is finding the right number in a table. Knowing what you are looking for cuts the time in half.
  3. 03Use "Cannot Say" generously. Verbal reasoning rewards strict reading. If the passage does not say it, the answer is "Cannot Say", not your own inference.
  4. 04Skip the impossible ones. Most tests do not penalise wrong answers more than skips. If you cannot see it in 20 seconds, flag and move on.
  5. 05Practise the exact format, not a generic stand-in. In-house bespoke assessment (no external psychometric provider) has its own rhythm, and a generic reasoning test is not the same. Intervyo's simulation is calibrated to this format, so you rehearse the real thing under real timing rather than a generic aptitude set.
