Why This Firm? How to Show Real Motivation in a BigLaw Lateral Interview

Quick answer: In a BigLaw lateral interview, every answer, especially "why this firm," needs to point back to a specific, logical reason you are moving: a step toward a named specialization, exposure to larger or more sophisticated clients, or a clearer path to the work you actually want to do. A hiring partner cannot hire on a feeling. They need a reason they can repeat to their colleagues when they advocate for you behind closed doors, and vague enthusiasm does not survive that conversation.

"I Want to Work Here" Is Not an Answer

Every lateral candidate says some version of "I'm really excited about this opportunity." It is true for almost everyone in the room, which means it tells the interviewer nothing. The candidates who stand out are the ones who can finish the sentence: excited about this opportunity because.

That "because" is the entire interview. It is the difference between an answer that makes a partner nod politely and an answer that gives them something to actually use.

Every Answer Needs a Stated Internal Motivation

Hiring partners are not just evaluating whether you can do the work. They are evaluating whether your move makes sense, because a move that does not make sense is a retention risk. Before the interview, decide which of these is genuinely true for you, and build your answers around it:

• A logical step toward advancement. You are moving because this role is a clear progression from where you are, not a lateral step in name only.
• Better or more sophisticated work. You want matters with higher stakes, more complexity, or more responsibility than your current seat gives you.
• Exposure to larger clients. You want to work on the scale of deal or dispute that only certain platforms and practice groups see regularly.
• Mastering a specific specialization. You have identified a narrow, named area, not "corporate" or "litigation" broadly, and this firm is where people actually build that expertise.

Pick one as your throughline. When you are asked "why are you leaving your current firm," "why this practice group," or "where do you see yourself in five years," the answer should trace back to the same motivation. Interviewers notice when a candidate's reasons shift depending on which question is asked. Consistency reads as conviction; a different justification for every question reads as improvisation.

Give the Hiring Partner a Script They Can Defend

Here is the part most candidates miss: the partner interviewing you is not the only person who has to be convinced. After you leave the room, they have to justify bringing you on to other partners, to a hiring committee, sometimes to an entire practice group. If your answer to "why this firm" was "I want to work here," they have nothing to repeat. If your answer was specific, they can say it back almost verbatim.

Compare these two:

• Weak: "I want to work here because it's a great firm with a great reputation."
• Strong: "I want to join this firm because I want to specialize in cross-border technology licensing, and this is one of the few groups in the market that runs that work at scale."

The second version gives the partner a sentence they can use. It is concrete enough to survive being repeated by someone else, in a room you are not in, days after your interview ended. That is the actual bar for a good answer, not whether it sounds good in the moment, but whether it still makes sense secondhand.

Other versions of a defensible reason:

• "Because this firm's culture, from what I've seen and heard, is exactly what I'm looking for at this stage of my career."
• "Because the group has built a team of people whose work I genuinely respect, including yours on [a specific matter]."
• "Because I want the kind of client exposure this platform gives associates at my level, which my current seat does not."

Each of these names something specific enough that a partner could write it down.

Rapport Has to Be Real, Because Forced Enthusiasm Shows

Interviewers form an impression before you finish your first sentence, and a large part of that impression comes from whether your interest in them and their practice reads as genuine or performed. This is not about pretending to like someone. Faked enthusiasm is usually more obvious, and more damaging, than mild neutrality.

The fix is preparation, not performance. Before the interview, research the specific person across the table the same way you would research the firm:

• Read their bio for background you can genuinely connect with: a shared law school, a past clerkship, a career path similar to the one you are considering.
• Look at their recent matters, publications, or speaking engagements for something you find genuinely interesting, not just impressive on paper.
• Note pro bono work, board service, or writing that actually resonates with you, and be ready to say specifically why.

The goal is to walk in already able to name one or two real reasons you find this person's practice, background, or approach worth respecting. When that respect is genuine and specific, it comes through naturally in how you ask questions and respond to what they say. When it is manufactured on the spot, it tends to come through just as clearly, in the other direction.

Put It Together: A Simple Answer Framework

When you are asked why you want to join a firm, structure the answer in three parts:

1. State the motivation. Name the specialization, the type of work, or the client exposure you are moving toward.
2. Explain why this firm specifically is the logical place to get it. Not firms in general, this one, based on something you can point to.
3. Connect it to something real about the firm or the person you are speaking with. A matter, a practice group structure, a piece of writing, something that shows you did the work before walking in.

That structure is what turns "I want to work here" into a sentence a partner can defend on your behalf, which is the actual job of a good interview answer.

Frequently Asked Questions

Q: What if I don't have one clear specialization yet?

A: You do not need a narrow specialization locked in for every interview, but you do need a clear direction. "I want to build deeper expertise in technology transactions, and I've focused my last two years of matters in that direction" is specific enough. Vague answers like "I'm open to anything" give the interviewer nothing to work with, even if it is honestly how you feel.

Q: Is it manipulative to research an interviewer so I can find things I respect about them?

A: No, as long as what you say is true. Research is simply preparation, the same as researching the firm's recent deals or practice group structure. The line is honesty: point out things you actually find impressive or relatable, not flattery you do not mean. Interviewers can tell the difference, and false praise tends to backfire more than saying nothing at all.

Q: How specific should my answer to "why this firm" actually be?

A: Specific enough that it would sound strange coming from someone applying to a different firm. If your answer to "why this firm" could be copy-pasted into an interview at three other firms without changing a word, it is too generic. Name the practice group, the type of matter, or the person's own work.

Q: What if my real reason for leaving is just better pay or better hours?

A: Those can be real factors, but they are rarely the full story, and leading with them makes the move look transactional rather than strategic. Find the underlying reason: better hours because it lets you take on more complex work without burning out, or better pay because it reflects a level of responsibility you are ready for. Frame the answer around the work and the trajectory, not the paycheck.

Q: Should I use the same "why this firm" answer at every interview during my search?

A: Use the same core motivation, since that consistency is what makes you credible, but tailor the specific firm-level reason to each conversation. The throughline (your specialization, your reason for moving) should stay constant. The evidence you point to for why this particular firm fits that goal should be different every time, because it is based on real research into that specific firm.
