Why McKinsey? A 3-Part Answer That Sounds Like You
'Why McKinsey?' looks simple but sinks many candidates. Here is a three-part structure, a worked example and a checklist for an answer that is specific, credible and yours.
What 'Why McKinsey?' is really testing
Interviewers at top consulting firms ask some version of 'Why consulting, and why us?' because the answer shows how you think. They are listening for self-awareness, evidence that you have done real research, and a motivation that will survive long hours and demanding clients. A rehearsed speech about 'impact' and 'smart colleagues' tells them very little.
This is general guidance based on how consulting fit and motivation questions are commonly assessed, not inside knowledge of any firm's scoring. The principle holds across most firms: the strongest answers are specific, honest and connected to something you have actually done.
The question can come in several forms: 'Why McKinsey?', 'Why consulting?', 'Why this office?' or 'Why not another firm?'. Prepare one core answer that flexes to all of them.
The three-part structure: field, firm, you
A reliable structure keeps your answer to around 60 to 90 seconds, which suits a live conversation and a timed video response alike. Build it in three layers, moving from the general to the personal.
Aim for roughly one sentence or two for each layer, then stop. Brevity reads as confidence.
- Why this kind of work (the field): what draws you to structured problem solving across different industries and problems, and what in your background shows you enjoy it.
- Why this firm (the specifics): two or three concrete things that distinguish it for you, drawn from your own research. Examples might be the breadth of sectors it serves, the way teams are staffed, how it develops people, or a particular practice area you want to learn from.
- Why you, and why now (the link): how your experience and goals connect to the first two points, and what you hope to contribute rather than only what you hope to receive.
Do your research without pretending to be an insider
Specifics are what separate a good answer from a generic one, but they must be accurate. Use sources you can stand behind: the firm's own website and published research, conversations with current or former staff, university careers events, and public reporting. Details about firm structure and programmes change, so check current information rather than relying on old forum posts.
Never claim to know how the firm assesses candidates internally, and avoid name-dropping a partner or report you cannot discuss in depth. If you mention a piece of published work, be ready for a follow-up like 'What did you take from it?'.
- Talk to at least one or two people who work or have worked there, and mention what you learned from them naturally ('When I spoke to someone on the…').
- Pick a practice area, sector or type of problem that genuinely interests you and be able to say why.
- Prepare a sincere answer to 'Why not another firm?'. It should rest on what you value, not on criticising competitors.
Reading about it isn't the same as doing it on camera.
Run a free timed mock interview →Use STAR to prove your motivation
Anyone can say they love solving problems. Evidence makes it believable. The STAR method (Situation, Task, Action, Result) lets you drop a compact story into the 'why you' layer. Keep the story short: this is a motivation answer, not a full competency response.
Here is an illustrative example of how the 'why you' portion might sound. It is a model for structure, not a script to copy.
'In my final year I led a student society whose membership was falling (Situation). I was asked to work out why and turn it around within one term (Task). I surveyed former members, found that events clashed with exam timetables, and proposed moving to shorter, fortnightly sessions, which I pitched to the committee with the data (Action). Attendance roughly doubled over the term, and I realised that the part I enjoyed most was breaking an unclear problem into pieces and persuading people with evidence (Result). That is why I want consulting: I want to do that daily, across industries. And what draws me to McKinsey specifically is the range of sectors and the chance to learn from people who have solved very different problems.'
Notice that the Result includes a reflection, linking the story back to motivation. That link is what makes STAR work here. Only use numbers you can verify, and never inflate outcomes.
Weak versus strong phrasing
Small wording changes make an answer sound considered rather than recited. Compare these approaches.
- Weak: 'McKinsey is the best firm in the world.' Strong: 'I want to work on problems where structured analysis changes a real decision, and I have seen that approach work in my own projects.'
- Weak: 'I want to learn a lot.' Strong: 'I want to build my skills in X, and I can see how working on Y would help me do that.'
- Weak: 'Everyone says the people are brilliant.' Strong: 'When I spoke to a consultant about her work on Z, I was struck by how much responsibility she had early on.'
- Weak: 'Consulting will open doors.' Strong: a clear reason you want the work itself, with an honest nod to your longer-term goals.
- Avoid: criticising other firms or your current employer, repeating the firm's marketing language word for word, and answering for more than two minutes.
Practise saying it out loud, on camera
An answer that looks good on paper can fall apart when spoken. Record yourself, check that you land at around 60 to 90 seconds, and listen for filler words, rambling transitions and lines that sound borrowed. Ask a friend to challenge you with follow-ups such as 'Why not a smaller firm?' or 'What would you do if you did not get an offer?'.
If you want realistic pressure, ScreenReady lets you practise timed, one-way video answers and get AI feedback on structure and delivery. Whichever method you use, rehearse until you sound natural, not memorised: know your three layers and your story, but let the wording vary.
Final checklist before the interview
Run through these points the night before.
- Can I explain why consulting in one or two sentences, backed by a real example?
- Do I have two or three accurate, specific reasons for this firm?
- Does my story follow STAR and end with a reflection that links to my motivation?
- Have I prepared for 'Why not another firm?' and 'Why this office?'
- Does my answer sound like me, and can I keep it under 90 seconds?
Frequently asked questions
How long should my 'Why McKinsey?' answer be?
Aim for roughly 60 to 90 seconds in conversation. That is enough to cover why consulting, why the firm and why you, with room for the interviewer to follow up. If they want more depth, they will ask.
Should I mention other firms I am applying to?
You do not need to volunteer it. If asked, be honest and focus on what attracts you to this firm rather than comparing or criticising others. Interviewers generally expect that serious candidates apply to several firms.
Is it a problem if I do not know anyone who works there?
No, but try to speak to someone if you can, as it gives your answer texture. University alumni networks, careers events and professional networking platforms are common ways to start a conversation. If it is not possible, rely on thorough reading of the firm's own published material.
Can I mention prestige or career prospects?
You can acknowledge long-term goals honestly, but do not make them the centre of your answer. Lead with the work, the learning and the environment, then mention career development as a supporting point.
