"Why you?" is the question that asks you to make the case for yourself, and most candidates find it harder than it sounds. Not because they lack relevant qualities or experience, but because translating what they have done into evidence of what a law firm needs requires a specific kind of thinking that most people do not do naturally. The instinct is either to list achievements (which tells the recruiter what you have done without explaining what it demonstrates) or to claim qualities directly (which tells the recruiter nothing they can verify). Neither approach scores well. This guide covers how firms think about this question, how to identify and frame the evidence you have, and how to build an answer that is genuinely persuasive rather than just accurate. The why you question works alongside the why this firm question to make the complete case for your application.

What the question is really asking

"Why you?" appears in many forms across different applications and interviews. Sometimes it is direct: "What would you bring to this firm as a trainee?" Sometimes it is framed around qualities: "Describe the attributes of a successful commercial lawyer and explain how you demonstrate them." Sometimes it is comparative: "What makes you stand out from other candidates?" The wording changes but the underlying question is always the same: do you understand what this firm needs in a trainee, and can you show with specific evidence that you meet that standard?

This framing matters because it shifts the task. The question is not asking you to describe yourself. It is asking you to demonstrate, through evidence, that you are capable of doing the job. A candidate who claims to be a strong communicator and a candidate who describes a specific situation in which they had to explain a complex legal concept to a client with no legal background are claiming the same thing, but only one of them is giving the recruiter something they can actually assess.

Firms are also, through this question, assessing whether the candidate understands what commercial legal practice actually requires. A candidate who identifies resilience, analytical thinking, and commercial awareness as the qualities they want to demonstrate signals a more sophisticated understanding of the role than one who leads with enthusiasm and a willingness to work hard. Enthusiasm and work ethic matter, but they are not differentiating qualities at this level of competition.

What firms are actually looking for in trainees

Before choosing which qualities to evidence, it helps to understand what law firms are genuinely trying to assess rather than just what their recruitment brochures say. The qualities that appear most often in trainee profiles and marking criteria across large commercial firms are:

Commercial awareness — not as a separate quality but woven into everything. A trainee who understands that clients care about outcomes, cost, and risk management rather than just legal accuracy will add value faster than one who does not.

Analytical ability — the capacity to read complex material, identify the relevant issues, and present a clear conclusion. This is what legal work requires at its most fundamental level.

Communication — written and verbal, but also the ability to adapt to different audiences. A trainee who can explain the same point to a partner, a junior colleague, and a non-specialist client in three different ways is significantly more valuable than one who communicates well only in their comfort zone.

Organisation and reliability — the ability to manage multiple demands simultaneously, meet deadlines without being chased, and produce accurate work under time pressure. Partners and associates build trust with trainees who deliver what they say they will deliver, when they say they will deliver it.

Resilience — sustained performance under pressure, the ability to absorb criticism and feedback without becoming destabilised, and the capacity to maintain quality when workloads are heavy and stakes are high.

Initiative — taking ownership of tasks rather than waiting to be told what to do next, flagging problems proactively rather than after they become crises, and contributing to the team beyond the minimum required.

Most applications ask you to address two or three of these rather than all of them, and choosing the ones you can evidence most specifically will always produce a stronger answer than trying to cover every quality at a surface level.

How to identify your evidence

The most common mistake at this stage is asking "what sounds impressive?" rather than "where have I actually demonstrated this?" The two questions produce very different answers. The first produces a list of qualities the candidate wishes they had strong evidence for. The second produces the actual evidence the candidate can speak to credibly under follow-up.

Work through your experience systematically before writing anything. For each quality you are considering, ask: when did I actually demonstrate this, in a specific situation, with a specific action, and a specific outcome? If you cannot answer that question for a particular quality, that quality should not be in your answer regardless of how relevant it is to the role.

The evidence does not need to come from legal work experience. Dissertation research demonstrates analytical ability and sustained intellectual effort. A challenging part-time job in retail or hospitality demonstrates communication, resilience, and the ability to work under pressure in a client-facing environment. A mooting competition demonstrates oral communication, the ability to construct and defend an argument, and performance under scrutiny. A society committee role demonstrates initiative, organisation, and often leadership. Any of these can serve as strong evidence if framed correctly.

The difference between claiming a quality and demonstrating it

This distinction is worth dwelling on because it is where most "why you?" answers lose their persuasive force.

Claiming a quality: "I have strong communication skills developed through my work at a law firm and my involvement in the university debating society."

Demonstrating a quality: "During my placement at a high street firm, I was asked to draft a summary of a complex conveyancing matter for a client who had no legal background and was anxious about the process. I rewrote it three times after feedback from the solicitor before it was sent, which taught me how much precision of language matters when you are trying to reassure someone who does not share your technical vocabulary. That experience changed how I approach written communication in a professional context."

Both candidates are making the same underlying claim about communication skills. Only the second gives the recruiter something to assess. The first describes activities. The second describes an experience with a specific challenge, a specific action, and a specific learning point, which is evidence rather than assertion.

The rule of thumb is simple: if the sentence you have written would be equally true of a candidate with no relevant experience at all, it is a claim rather than evidence and it needs to be replaced with something specific.

How to structure your answer

Most "why you?" answers work best with two or three qualities, each supported by one specific piece of evidence, explained in enough depth that the recruiter can see both the experience and what it demonstrates. The structure for each quality is the same: identify the quality, describe the experience that demonstrates it, explain what specifically in that experience demonstrates the quality, and connect it back to why it is relevant to a trainee at this firm.

This last step, connecting back to the firm, is what distinguishes a strong "why you?" answer from a strong competency answer. The evidence might be the same, but the framing is different. A competency answer is asking "what did you do?" A "why you?" answer is asking "why does what you did make you right for this role at this firm?" The connection to the firm should be explicit, not implied.

A worked example

Communication is a core skill for trainee solicitors, particularly when working with clients across jurisdictions and practice areas. I developed this skill in practice during an internship where I acted as a point of contact between lawyers and clients from different jurisdictions, requiring me to explain legal concepts accurately and in plain language. This experience sharpened my ability to adapt my communication style to different audiences and levels of understanding. I strengthened this further through content-led work that involved translating complex business ideas into clear, engaging written material for a large readership. Together, these experiences reflect my ability to communicate with precision, clarity, and commercial awareness, qualities that are essential when advising clients in a commercial law firm.

What this answer does well

It opens by naming the quality and explaining why it matters in the specific context of a trainee solicitor, which is a stronger framing than simply claiming to possess the quality. It draws on two distinct pieces of evidence, the internship and the content work, which gives the claim more credibility than a single example. Each piece of evidence is described with enough specificity that the recruiter can picture what the candidate actually did. And it closes by connecting the evidence to the requirements of the role rather than leaving that connection implicit.

Where it could go further

The phrase "content-led work" is slightly vague and would be stronger if it named the specific context (a student publication, a legal blog, a commercial newsletter) rather than using a general description. "A large readership" could be more specific. And "commercial awareness" in the closing line is asserted rather than demonstrated within this particular example, which slightly weakens it. In a longer answer with more space, both of these could be developed further.

How development matters as much as achievement

One thing the best "why you?" answers do that weaker ones do not is show growth rather than just outcome. Firms are recruiting trainees, not finished lawyers, and they are genuinely interested in candidates who have reflected on what they have done and what it taught them, rather than ones who simply list positive outcomes.

An answer that describes a difficult experience, explains specifically what you did about it, and then articulates what changed in how you approach similar situations since signals a level of self-awareness and professional maturity that a list of achievements does not. Two candidates might have identical CVs in terms of the experiences they have had. The one who has thought carefully about what those experiences taught them will almost always present more compellingly, because they are giving the recruiter evidence of how they think rather than just evidence of what they have done.

Common mistakes

Listing achievements without explaining what they demonstrate. The recruiter is not assessing whether your experiences were impressive. They are assessing what those experiences show about how you think, communicate, and work under pressure.

Claiming qualities you cannot evidence specifically. If you claim to be commercially aware but cannot point to a specific experience where commercial awareness was relevant, the claim is hollow.

Trying to cover too many qualities. Two qualities demonstrated in genuine depth will consistently outscore five qualities stated flatly. Choose the qualities you can evidence most specifically.

Writing in a way that could describe any applicant. "I am a hardworking and motivated individual who is passionate about law" applies to every candidate in the pool. Everything in your answer should be specific to you.

Forgetting to connect the evidence back to the firm. A strong "why you?" answer is not just a list of your qualities. It is an argument for why your particular combination of qualities makes you right for this firm at this stage. The connection needs to be made explicitly.
