If you are preparing for law firm interviews or assessment centres, our Application Process hub covers every stage of the recruitment process from written applications to offers.

Competency questions are one of the most common reasons strong candidates fall short in law firm interviews, not because they lack relevant experience, but because they frame it badly, structure it loosely, or choose the wrong example for the question being asked. A well-lived experience described without structure will consistently score lower than a modest experience described with precision and clarity. This guide covers everything: how competency questions work, the STAR structure that firms expect, how to choose and adapt examples across question types, the specific qualities law firms are scoring, and the mistakes that cost candidates marks most often.

What firms are actually scoring

The premise behind competency questions is straightforward: past behaviour is the best predictor of future behaviour. When a firm asks "tell me about a time you managed competing priorities," they are not interested in what you would theoretically do in that situation. They want evidence of what you actually did, and they are using that evidence to infer how you will behave as a trainee.

Every competency question targets a specific quality, and knowing which quality a question is targeting before you answer is the first step. Many candidates answer well in the abstract but fail to connect their answer to what was actually being assessed. The qualities that appear most often at law firms are:

Teamwork — working effectively with others, managing disagreement constructively, and contributing to group outcomes even when things are not going smoothly

Communication — explaining complex ideas clearly to different audiences, adapting your style to the person and context, and listening as well as speaking

Resilience — maintaining performance under sustained pressure, recovering from setbacks without losing quality, and learning from difficulty in a way that genuinely changes future behaviour

Organisation and time management — managing multiple genuine demands simultaneously, prioritising deliberately rather than reactively, and meeting deadlines even when conditions are difficult

Leadership and initiative — taking ownership without being asked, making decisions under uncertainty, and influencing people who did not have to listen to you

Problem solving — identifying the key issue in a complex situation and taking a structured approach to resolving it

Commercial awareness — understanding how businesses operate and how legal advice connects to commercial outcomes

Attention to detail — producing accurate work and catching errors before they cause problems

Firms typically rotate through several of these in a single interview to build a picture of the candidate across multiple dimensions, which means the ability to deploy different experiences against different question types is more valuable than having one strong story that only works for one competency.

These map directly to the top skills commercial law firms look for in graduates.

The STAR structure and how to use it properly

STAR stands for Situation, Task, Action, Result, and it is the framework law firms are calibrated to score competency answers against. Assessors reviewing multiple candidates back to back rely on it to compare answers consistently, which means an answer that clearly provides all four elements will almost always outscore one with better content but weaker structure.

Situation

One specific context, described in ten to fifteen seconds. Not "during my time at X" or "I often find myself in situations where..." but a single occasion with enough concrete detail to orient the interviewer. The Situation exists to set the scene, not to tell a story, and most candidates spend too long here at the expense of the step that matters most.

Task

Your specific responsibility in that situation. What were you trying to achieve, what was expected of you, and what was at stake? This step is where many answers become inadvertently passive. "I was part of a team that..." is not a Task statement with any individual responsibility in it. "I was responsible for coordinating the outreach to external suppliers and ensuring the materials were ready by Thursday" is.

Action

This is where the mark is won or lost, and it should take up fifty to sixty seconds of a ninety to one-hundred-and-twenty second answer. The Action step is where you demonstrate the competency being assessed, and it should describe specifically what you did, how you thought about it, what decisions you made, and what judgment you exercised rather than simply what happened.

Three principles matter here more than anything else. First, use "I" not "we" throughout, because assessors cannot score a team and isolating your specific contribution is the only way to give them something to assess. Second, show the reasoning behind the action rather than just the action itself, because "I escalated the issue to my supervisor because I judged that the potential client impact outweighed the time cost of involving someone more senior" is far more useful evidence than "I escalated the issue to my supervisor." Third, be honest about difficulty, because the best Action steps describe situations that were genuinely hard and explain specifically what you did about that difficulty, which is more interesting to an assessor than a smooth story where everything went to plan.

Result

A concrete outcome followed by a genuine learning point. Results do not need to be dramatic: a process you improved, a deadline you met under genuinely difficult circumstances, an error you caught before it reached a client. What matters is that the result is clearly connected to your action and that you take appropriate credit for it. The learning point, one sentence explaining what you took from the experience and how it has changed how you approach similar situations since, is the step most candidates skip and often the most memorable part of a strong answer.

Why most answers fail before the example is even chosen

The mistake candidates make most often is choosing the most impressive-sounding experience rather than the one that best demonstrates the specific quality being tested. An experience from a prestigious internship that you cannot speak to with precision will score lower than a Saturday job you can describe in specific detail, because the Action step of the prestigious experience will be thin while the Action step of the Saturday job will be rich.

Before choosing an example for any competency question, apply three filters. Does the experience actually demonstrate the specific quality being asked about rather than a quality adjacent to it? Can you describe in concrete detail what you did, why you did it, and what judgment you exercised? And is there a result you can state clearly? If the answer to any of these is no, choose a different example regardless of how impressive the context sounds.

Building examples that work across multiple questions

The most efficient preparation is not to memorise one answer per competency but to identify five to seven strong experiences that you can adapt depending on which quality is being assessed, shifting the emphasis in the Action step to foreground the relevant competency.

Most strong experiences are versatile in exactly this way. An experience involving a difficult team dynamic might demonstrate teamwork, communication, resilience, and leadership simultaneously depending on which aspect you emphasise. A period of managing competing academic and work commitments might serve for organisation, resilience, or commercial judgment. Knowing your experiences well enough to shift the emphasis is more valuable than having a script for every possible question, and it means your answers remain natural under follow-up rather than collapsing when the interviewer probes.

When building your example bank, draw from the full range of your experience. Legal work experience (vacation schemes, law clinics, paralegal roles) is valuable but not the only source of strong material. Dissertation research, mooting, and group coursework provide genuine evidence of analytical ability and organisation. Society committee roles, sports teams, and charity work demonstrate leadership and teamwork in contexts where the stakes were real. And part-time work in retail, hospitality, or service roles, which most candidates undervalue, is often where the strongest resilience and communication evidence lives, because those environments test exactly the qualities law firms care about under genuine pressure. For specific guidance on framing that kind of experience, see our guide to retail experience and career-ready skills.

The qualities firms test most, and where candidates go wrong on each

Teamwork. The strongest examples involve a genuine challenge within the group, not a successful outcome with no friction. A team where someone was not delivering, where two members had conflicting views, or where the structure broke down and you helped fix it gives an assessor something to evaluate. A team where everything went well and you cooperated effectively tells them almost nothing. Avoid answers that describe the team's achievement rather than your individual contribution, and avoid using "we" throughout the Action step.

Resilience. Choose something genuinely difficult, because candidates who reframe an easy situation as challenging in order to seem more resilient are immediately apparent to experienced assessors. Describe what made the situation hard, what you specifically did in response, and what concretely changed as a result. The learning point is especially important here because resilience evidence without a clear learning point suggests you endured something rather than grew from it.

Communication. The most useful examples involve a genuine adaptation challenge: explaining something technical to someone with no specialist knowledge, managing a conversation with someone who was frustrated or confused, or delivering feedback that needed to be both honest and careful. A presentation or report alone is rarely strong evidence unless you can describe what was specifically difficult about the communication dimension and what you did about it.

Leadership and initiative. At graduate level this rarely means managing a large team, and most candidates who try to engineer a story about managing others come across as unconvincing. What firms are actually looking for is evidence of identifying something that needed doing and doing it without being asked: reorganising how a committee operated, stepping up when a project stalled, catching a problem before anyone else noticed it. The title of your role matters far less than the specificity of your action. For a full treatment of how to build and evidence leadership at this stage, see our leadership skills guide.

Organisation and time management. The key is making the prioritisation logic explicit, explaining not just that you managed multiple demands but how you decided what to do first and why, because that reasoning is what demonstrates genuine judgment rather than simply the ability to be busy. The strongest examples describe front-loading preparation before a pressure period begins rather than managing a crisis during one, because the former requires anticipation and the latter just requires endurance.

Problem solving. Show the structure of your thinking: how you identified the key issue, what options you considered and why you ruled some of them out, and why you chose the approach you did. The problem does not need to be complex or high-stakes, and a well-reasoned approach to a simple problem is more convincing than a vague description of handling something that sounded important.

Commercial awareness. Show that you understood the commercial context of a decision rather than just the task in front of you. Any experience where you observed or contributed to a business decision counts, whether that was a law firm, a retail environment, or a student enterprise. For a full framework, see our commercial awareness guide.

Attention to detail. The best examples are proactive: catching an error before it reached a client or supervisor, identifying a discrepancy that no one else had noticed, implementing a checking process that improved accuracy for a whole team. Describing a role where accuracy was generally required is not the same as demonstrating a specific moment where your attention to detail made a concrete difference.

A fully worked example

Question: Tell me about a time you had to manage competing priorities under time pressure.

Situation: In the second year of my law degree, I had three assessments falling within the same ten-day period: a timed contract law essay, a group moot, and a constitutional law coursework submission. I was also working Saturday shifts at a coffee shop that I could not reduce without giving four weeks' notice.

Task: I needed to deliver all three pieces of work to the standard I was capable of while maintaining my work commitment, without the kind of last-minute compression that I knew would compromise the quality of the essay in particular.

Action: I started by mapping out the ten days on paper with every commitment written in and identifying where the genuine pressure points were. The moot came first and was the only piece requiring collaborative preparation, so I spoke to my mooting partner the week before the assessment period and proposed that we front-load everything, completing our skeleton arguments and running two full practice sessions before the ten days began. That decision freed the assessment window itself for the essay and the coursework. For the constitutional law submission, I wrote a detailed plan in the week before the window so that when I sat down to write I was working from a clear argument structure rather than planning and drafting simultaneously, which I knew from experience would take significantly longer. On my Saturday shift during the busiest week, I used my commute to review notes rather than treating the journey as downtime.

Action: I submitted all three pieces on time and achieved a first in the contract essay, a distinction in the moot, and a 2:1 in constitutional law. What I took from it was something I now apply consistently: the decisions that matter most in a high-pressure period are almost always made before it starts, and investing time in preparation and structure in the days before a deadline is more valuable than any amount of effort during the deadline itself.

Notice that the Action step takes up more than half the answer, which is deliberate. The Situation and Task together take perhaps twenty to twenty-five seconds. The Action takes sixty. Most candidates invert this ratio, spending most of their time on Situation and Task and then rushing through what they actually did, which is the only part the assessor is scoring. If you find your Action step is thin, the answer is not to compress the Situation further but to go back and think more carefully about what you actually did and why.

The mistakes that consistently cost candidates marks

Choosing vague or composite examples. "I often have to manage competing priorities in my role as..." is not a competency answer. One specific occasion is required, with enough concrete detail to make the Action step rich.

Spending too long on Situation and Task. Many candidates construct a detailed backstory and then describe their actions in two sentences, leaving the assessor with nothing to score.

Using "we" throughout the Action step. If it was a group task, isolate your contribution. What did you specifically decide, propose, or do?

Skipping the learning point in the Result. An outcome alone is incomplete. What changed in how you approach similar situations since?

Memorising scripts. Rehearsed answers are immediately apparent and collapse under follow-up questions. Practise your examples until you know them well and can speak to them naturally, not until you can recite them word for word.

Choosing impressive over relevant. The experience that most directly demonstrates the specific competency being tested will always outscore a more impressive experience that only loosely connects to what was asked.
