Critical thinking and verbal reasoning
What it tests. Semantic precision, isolating primary commercial drivers from background noise, and structural integrity in arguments.
Worked example. Instead of a 'true, false or cannot say' assumption test, you analyse a recent macroeconomic event or transaction affecting Sidley's clients and synthesise the legal implications of a multi-billion-pound private equity restructuring without contradicting your premise.
Common traps. Prose fluff (ornate language hiding a thin grasp of the deal) and logical leaps (claiming a regulatory shift will 'ruin the market' without mapping the mechanism, e.g. compliance costs leading to margin compression).
How to handle it. Use strict deductive logic with an empirical or legal anchor for every claim, applying the PEEL structure (Point, Evidence, Explanation, Link).
Situational judgement and professional conduct
What it tests. Resource allocation, upward management, transparency and high-stress interpersonal diplomacy.
Worked example. A partner poses a live dilemma: a senior associate needs a closing checklist by 9pm; at 8:30pm a partner asks you to research an urgent sanctions issue. Both expect total priority. How do you manage it?
Common traps. The 'hero' complex (claiming you will do both all night without communicating, a dangerous lack of risk management) and passing the buck (telling the partner to sort it out with the associate).
How to handle it. Acknowledge competing commercial priorities, communicate immediately, clarify hard deadlines, propose a structured solution (another trainee assists, or flag the partner mandate to the associate), and never compromise client delivery.
Commercial and numerical reasoning
What it tests. Financial literacy, understanding profitability drivers, and interpreting quantitative data to formulate legal-risk strategies.
Worked example. You are given a basic profile of a company divesting a subsidiary, with high-level figures on debt-to-equity or revenue multiples, and asked why a private equity sponsor might find the target attractive despite high leverage.
Common traps. Quantitative phobia (freezing at EBITDA, debt servicing or valuations) and divorcing law from finance (forgetting that debt covenants and material adverse change clauses exist to protect the parties' financial positions).
How to handle it. Read the Financial Times and LexisNexis business updates daily; understand how an LBO works, why rates affect cross-border M&A volume, and how debt structures drive a firm's transactional pipeline.
