What a consulting interview actually probes
Expect a case interview: a business problem, often about entering a market, fixing declining profitability, or evaluating an acquisition, that you work through with the interviewer rather than solve silently and report back. Expect the interviewer to interrupt with new information partway through, testing whether you can adjust your framework rather than defend an early guess.
Market sizing shows up as its own question type, a number with no clean data available, where you're graded on the assumptions you state out loud more than the final figure. A fit interview runs alongside the case, usually structured around leadership, teamwork, and a time you influenced a decision without formal authority.
Interviewers watch closely for whether you ask clarifying questions before diving in, since a consultant who starts solving without scoping the problem first is a real red flag.
Question types to expect
Case interviews
Full business problems worked through with the interviewer in real time, testing structure and adaptability more than a single correct conclusion.
- Our client's profits have dropped 20% over two years. How would you figure out why?
- A retail client is considering entering a new country. How would you evaluate whether they should?
- Should this client acquire a smaller competitor? Walk me through how you'd decide.
Market sizing
Estimation questions with no available data, graded on the assumptions and structure behind the number more than the final answer.
- How many coffee shops are there in Chicago?
- Estimate the annual revenue of all gyms in a mid-sized city.
Fit and leadership
Behavioral questions about leadership and teamwork, usually looking for a specific moment of influence or disagreement rather than a general leadership philosophy.
- Tell me about a time you influenced a decision without having formal authority.
- Describe a time you disagreed with a team's direction and what you did about it.
Structured problem-solving
Open-ended prompts that reward breaking a vague problem into a clear framework before attempting to answer it.
- How would you decide whether a company should launch a new product line?
- Walk me through how you'd approach a problem you've never seen before.
How Intervieux helps you prepare
The comprehensive interview type mixes case-style problem-solving with fit questions in a single session, closer to how a real consulting loop actually runs, rather than practicing the two in complete isolation. The general interview type is useful for fit-focused practice on its own, particularly leadership stories that come up regardless of which firm or practice you're targeting.
Communication and Behavioral both carry real weight in scoring here, since a case interview is judged as much on how clearly you narrate your thinking as on the structure itself.
The penalty system deducts for not asking the interviewer any questions during the session, worth taking seriously in consulting practice specifically, since scoping a case by asking clarifying questions before diving in is close to the actual job, not just interview etiquette.
Practice, then apply
Practice privately, then apply for real
Practice sessions stay private, giving you room to work through a rough case framework or a shaky market sizing estimate a few times before a real interviewer hears the first version. Since case loops often move fast once a firm decides to interview you, it helps that applying costs nothing on the board and one click starts a live AI screening interview built from that specific employer's posting.

Frequently asked questions
Will the AI interviewer actually interrupt me with new information, like a real case interview?
The session moves through a real back-and-forth rather than a single monologue, giving you practice adjusting your framework as a case develops, closer to how an actual case interview unfolds than a one-shot answer would be.
Is market sizing scored on the final number or the reasoning?
In real consulting interviews the assumptions and structure behind the estimate matter more than the exact figure, and that's the part worth practicing directly rather than memorizing benchmark numbers.
Does it actually matter if I don't ask any questions during the interview?
Yes. The penalty system deducts for not asking the interviewer any questions, and in a consulting context it lines up with a real evaluation criterion, since scoping a problem by asking questions first is part of the actual job.
Can I practice fit questions separately from a full case?
Yes. The general interview type works well for fit and leadership questions on their own, useful if you want focused practice on that half of the loop before combining it with case-style questions.
