Key Takeaways

 

Integration Consulting runs a five stage hiring process: application, aptitude test, a first round fit and competency interview, a second round pairing one case study with one competency session, and a final assessment day with two founding partners.

 

• Glassdoor's 87 interview reports put the average process at 34 days from first contact to decision

 

• An aptitude test screening numerical reasoning, verbal reasoning, and problem solving comes before you meet a single interviewer

 

• Reported cases cluster around market sizing, cost synergies, and freight and logistics, which mirrors the firm's actual client work

 

• Interviewers score three published dimensions: problem solving, analysis, and interpersonal skills

 

• Two founding partners sit in on the final round, which is rare at a firm LinkedIn lists at 201 to 500 employees

 

• Half of reported candidates got their interview by applying online, so a strong application still matters more than a referral here

 

What Is the Integration Consulting Interview Process?

 

The Integration Consulting interview process has five stages: an online application with a CV and cover letter, an aptitude test covering numerical and verbal reasoning, a first round fit and competency interview, a second round pairing one case study with one competency session, and a final assessment day with two of the firm's founding partners.

 

1. Apply: submit your CV and cover letter online, showing leadership, problem solving, teamwork, and entrepreneurial drive
   
   
2. Aptitude test: online or offline testing of numerical reasoning, verbal reasoning, and problem solving
   
   
3. First round: a fit and competency conversation about your past achievements, plus a short problem to solve
   
   
4. Second round: two sessions, one full case study and one focused on competency and motivation
   
   
5. Final round: an assessment day where you meet two of Integration's founding partners

 

That structure comes straight from the firm's own careers page. Treat it as the spine of your prep, then adjust for your office, because reported processes vary.

 

London candidates describe three rounds rather than five stages, with a market sizing and competency interview first, two cases second, and a final competency conversation with a senior leader. Brazilian candidates more often describe a short HR screen, then a case with a manager, then partner interviews. The building blocks are identical even when the packaging differs.

 

Timing runs long. Glassdoor puts the average hiring process at 34 days across 87 submitted interviews, with analyst level roles in Brazil sometimes stretching past two months. Plan your other applications around that, and do not assume silence means rejection.

 

Who Is Integration Consulting and Why Does That Matter in Your Interview?

 

Integration Consulting is a strategy and management consultancy founded in 1995 in Sao Paulo, Brazil. Its LinkedIn page describes serving more than 870 clients across over 85 countries, with offices in Buenos Aires, Chicago, London, Mexico City, Munich, Santiago, and Sao Paulo.

 

First, a disambiguation that trips up a lot of applicants. Searching this term also surfaces roles for "integration consultants" who connect software systems using APIs and middleware. That is a different job at a different kind of company, and none of that technical material will help you here.

 

What makes this firm distinct is implementation. Integration does not stop at the recommendation slide, and its service lines run through marketing and sales, supply chain consulting, finance and management, leadership and organization, and post merger integration.

 

This shapes your cases directly. A firm that gets paid to land the change asks case questions about freight costs, warehouse networks, cost synergies, and zero based budgeting far more often than it asks about digital disruption. Candidates on Glassdoor report exactly that mix.

 

It also shapes your fit answers. Integration sits in the same competitive space as the top boutique consulting firms, so interviewers expect you to explain why a specialist implementation shop appeals to you more than a generalist brand name. "It is a great firm" will not survive a partner follow up.

 

What Is on the Integration Consulting Aptitude Test?

 

The Integration Consulting aptitude test assesses numerical reasoning, verbal reasoning, and problem solving, and the firm delivers it online or offline depending on the office and hiring cycle. It screens candidates before any human interview, so a weak score ends your process regardless of how strong your CV is.

 

Glassdoor's breakdown of reported stages backs this up. Across 87 interview reports, a skills test appeared in 14% of processes, a personality test in 9%, and an intelligence style test in 5%.

 

Numerical reasoning here means reading a chart or table under time pressure and answering questions about percentages, ratios, and growth rates. It is not advanced math. It is fast, accurate arithmetic with a clock running, which is the exact skill your case interviewers will test again later by hand.

 

Three things fix most test failures. Practice mental math daily until percentage and ratio calculations feel automatic, sit at least two full length timed practice tests so pacing stops surprising you, and learn to skip a question you cannot crack in 45 seconds rather than burning three minutes on it.

 

The personality questionnaire is not something to game. Integration builds its hiring around a published set of values, and inconsistent answers designed to look impressive tend to contradict what you say in your fit interview.

 

What Fit and Behavioral Questions Does Integration Consulting Ask?

 

Integration Consulting fit interviews focus on motivation, past achievements, and cultural alignment, and the two questions candidates report most often are why you want consulting and why you want Integration specifically. Expect follow ups on how you handle difficult situations, how you work in teams, and how you have responded to feedback.

 

Real questions reported by candidates on Glassdoor include the following.

 

• Why are you interested in consulting, and specifically in Integration Consulting

 

• Tell me about yourself and why you want to transition your career into consulting

 

• Give me an example of feedback you received and what you did with it

 

• Would you rather specialize in one type of project or rotate across many

 

• How would you describe your interpersonal relationships in a corporate environment

 

That fourth question is worth pausing on. Integration builds career paths around an annual conversation where each professional lays out the projects and experiences they want, so the question is testing self awareness rather than fishing for a "both" answer.

 

The feedback question is not filler either. The firm runs 360 degree feedback on a biweekly basis and structured evaluations on every project. Someone who cannot describe a piece of hard feedback they acted on is a poor fit for that rhythm, and your interviewer knows it.

 

Structure every answer using the STAR method so your stories land in under 90 seconds. Rambling is the single most common reason strong candidates lose points here.

 

Integration interviewers assess communication style alongside content, which raises the bar on delivery in a consulting fit interview. Practice out loud, not in your head.

 

How do you answer "why Integration Consulting?"

 

Build your answer on the firm's seven published values rather than its client list. Integration lists respect, dignity, justice, cooperation, simplicity, honesty, and truth on its culture page, and states that career progression rests on behavior as much as technical performance.

 

Here is how to translate each one into interview evidence.

 

Value	What it looks like at Integration	How to show it in the interview
Respect	Professionals are recognized as individuals, not by title	Credit teammates by name and role in your stories
Dignity	Applies to how colleagues treat each other, not just clients	Describe a conflict you handled without blaming anyone
Justice	Evaluation tied to behavior, not just output	Talk about how you allocated work or credit fairly
Cooperation	Delivery happens as part of an effective team	Use "we" for outcomes and "I" for your specific contribution
Simplicity	Solutions clients can actually implement	Answer the question asked before adding nuance
Honesty	Professionals are expected to speak up and challenge	Say "I do not know" instead of bluffing a number
Truth	Seeing reality clearly and adjusting to it	Name a failure and what it actually cost

Having coached hundreds of candidates through firm specific fit rounds, I can tell you the difference between a good and a great answer here is specificity. Naming one value and showing it through a story beats listing all seven. Candidates who recite the values back verbatim sound rehearsed, which works against the authenticity the firm says it prizes.

 

Your why consulting answer needs the same treatment. If you want a proven structure for the twenty or so behavioral questions that cover almost every consulting interview, my fit interview course walks through answer templates and example responses in a few hours.

 

Will your Integration Consulting interview be in English?

 

Possibly, and this catches candidates off guard. One Sao Paulo candidate reported that part of the interview was conducted in English specifically to assess communication and professional presence, even though the rest of the conversation was in Portuguese.

 

Integration runs seven offices across three continents and staffs projects internationally, so working English is a practical requirement. If you are interviewing outside an English speaking office, rehearse your tell me about yourself answer and your two strongest stories in both languages before the first round.

 

What Are Integration Consulting Case Interviews Like?

 

Integration Consulting case interviews are interviewer led business problems drawn from the firm's real client work, typically running 30 to 45 minutes each. You will face at least one full case in the second round, and often a market sizing question earlier, with cases weighted toward supply chain, cost reduction, and revenue estimation.

 

The most useful fact about these cases comes from the firm itself: the case you get will likely be based on a project your interviewer actually worked on for a client. That single detail should change how you prepare.

 

Real cases reported by candidates include the following.

 

• Restaurant revenue: estimate how much a restaurant makes in a year

 

• Cinema forecast: build a revenue forecast for a cinema, framed as a market sizing question

 

• Cost structure synergies: identify synergies in a combined cost structure after a merger

 

• Freight and logistics: reduce or optimize transportation costs for a client network

 

Notice the pattern. Two of those four are estimation problems, which means your market sizing technique carries more weight at Integration than at firms that lean on profitability trees.

 

The other two map directly onto the firm's supply chain and post merger integration practices. Working through a supply chain case interview or two before your second round is a better use of an evening than another generic market entry drill.

 

What four steps does Integration expect you to follow?

 

Integration publishes the exact approach it wants to see, which almost no firm does. Its case preparation page lays out four steps to solve a case: understand, structure, analyze, and conclude.

 

1. Understand: listen carefully, take notes, ask clarifying questions, summarize the problem back, and verify the objective
   
   
2. Structure: take time to think, identify and prioritize the key issues, generate a hypothesis, and communicate your approach
   
   
3. Analyze: ask questions driven by your structure rather than at random, test your hypothesis, and sanity check odd results
   
   
4. Conclude: synthesize rather than recap, refer back to your hypothesis, state a clear recommendation, and add next steps

 

Two words in that list do heavy lifting. "Verify the objective" means confirming whether the client wants to maximize profit or sales before you build anything, and "synthesize rather than recap" means your conclusion must argue a position, not replay the numbers you just calculated.

 

The firm also flags sanity checking explicitly, using the example of asking whether milk should really cost ten pounds a pint. Interviewers notice when a candidate reports an absurd answer without blinking, and that alone can sink an otherwise clean case.

 

What do Integration interviewers score you on?

 

Integration publishes three scoring dimensions and the sub criteria under each. Most candidates over invest in the first and under invest in the third.

 

Dimension	What they assess	Where candidates lose points
Problem solving	Breaking down complex problems, structured logical thinking, creativity	Reciting a memorized framework that does not fit the question
Analysis	Accurate calculations, reasonable assumptions, structured questions, useful insights	Producing a number without saying what it means for the client
Interpersonal	Synthesis, handling ambiguity, communication style and content, attitude	Going silent for three minutes or getting rattled by a challenge

That third row is where I see the most avoidable failures. The firm says outright that it wants collaborators who communicate clearly and work under pressure without losing their cool, which means how you behave when a partner pushes back matters as much as whether your math was right.

 

Custom case interview frameworks beat memorized ones here, since a freight optimization case and a merger synergy case share almost no structure. If you want to build that skill quickly, my case interview course teaches a method for structuring any case in as little as 7 days.

 

What Happens in the Integration Consulting Final Round?

 

The Integration Consulting final round is an assessment day where you meet two of the firm's founding partners. Some candidates report a second case at this stage, while others describe it as a competency and motivation conversation, so prepare for both.

 

Meeting founders at the final stage tells you something real about the firm. At a consultancy this size, the founding partners are still personally approving hires, which means culture fit is not a box being checked by a recruiter.

 

Prepare differently for this round. Founders ask about trajectory and motivation rather than technique, so your answers should connect what you have done to what you want to build over the next several years. Generic ambition reads as unserious to someone who started the company in 1995.

 

Come with three sharp questions of your own. The firm frames its process as mutual, and candidates who ask nothing at a founder meeting signal low interest, which is a common way to lose consulting final round interviews after clearing every earlier hurdle.

 

How Hard Is It to Get an Integration Consulting Offer?

 

Integration Consulting interviews rate as average difficulty on Glassdoor, with a very positive overall experience rating across 87 submitted interview reports as of August 2026. The process is more demanding than the difficulty score suggests, because it stacks an aptitude test, multiple cases, and a founder meeting into roughly 34 days.

 

Metric	Reported figure
Interview reports analyzed	87
Average process length	34 days
Difficulty rating	Average
Applied online	50% of candidates
Campus recruiting	20% of candidates
Recruiter or employee referral	11% each
Most reported role	Business Analyst, with 21 reports

The referral number is the useful one. Only 11% of reported candidates came through an employee referral, compared with half who simply applied online, so your consulting resume is doing more work here than it would at a firm where networking dominates.

 

Be prepared for silence after a rejection. At least one candidate reported receiving an automated response stating the firm does not give feedback on selection processes, so build your own review habit instead of waiting for theirs. Writing down what went wrong within an hour of each round is worth more than any feedback email.

 

A tailored consulting cover letter matters more than usual too, since the firm explicitly asks for one and tells applicants to demonstrate leadership, problem solving, teamwork, and entrepreneurial drive. Those four words are your outline. If yours needs work, my resume review service includes unlimited revisions with 24 hour turnaround.

 

How Should You Prepare for an Integration Consulting Interview?

 

Give yourself four to six weeks. That is enough time to pass the aptitude test, build a case bank weighted toward the firm's actual practice areas, and rehearse fit answers that hold up under a founder's follow up questions.

 

Tip #1: Build a case bank around supply chain and cost reduction

 

Reported cases cluster around freight, logistics, and merger synergies rather than the market entry and new product problems most casebooks over index on. Work through at least six cases in those areas.

 

Keep one profitability case interview in your rotation as a baseline, since cost reduction problems are profitability problems with the revenue side held constant.

 

Tip #2: Drill estimation until you can do it out loud

 

Two of the four publicly reported cases are estimation problems, and both were given early in the process. Practice estimating annual revenue for a restaurant, a cinema, a gym, and a supermarket until you can talk through the structure without pausing.

 

Use clean round numbers and say your assumptions out loud as you make them. The firm lists reasonable assumptions and estimates as an explicit scoring criterion, which means a defensible assumption you stated beats a precise one you hid.

 

Tip #3: Research your interviewer's project history

 

Since cases are usually drawn from work the interviewer actually did, spending 20 minutes on their LinkedIn profile before the round pays off more than another practice case. Look for their industry focus and service line.

 

If they have spent three years on beverage supply chains, skim how distribution economics work in that category. You will not predict the case, but you will recognize the terrain faster than a candidate who did not look.

 

Tip #4: Anchor your motivation in implementation

 

The firm's identity rests on delivering change rather than handing over a recommendation and leaving. If your reason for wanting Integration could be pasted into an application for any strategy firm, it is not finished.

 

Name a specific service line, connect it to something you have actually done, and say what you want to learn there. That structure survives follow up questions.

 

Tip #5: Rehearse a 60 second synthesis

 

Integration explicitly asks for synthesis rather than a recap in the conclude step, and this is where most candidates blur the two. A recap lists what you found, while a synthesis states a recommendation, gives two supporting reasons, names a risk, and proposes a next step.

 

Time yourself. If your conclusion runs past 90 seconds, you are recapping.

 

Tip #6: Practice being interrupted

 

These are interviewer led cases, which means you will be redirected mid analysis. Candidates who treat a redirect as a mistake lose composure, and composure sits inside the interpersonal criterion the firm actually scores.

 

Ask a practice partner to interrupt you twice per case and change direction once. Getting comfortable with that is one of the higher yield case interview tips for any interviewer led format.

 

Tip #7: Prepare questions for every single round

 

The careers page tells first round candidates they can ask anything they like about the firm, which is an invitation most people waste. Prepare three questions per round and never repeat one.

 

Ask a consultant about staffing and project rhythm, ask a manager about how the do's and don'ts allocation conversation works in practice, and save the questions about firm direction for the founders.

 

Preparing for the Integration Consulting interview comes down to one thing that most candidates skip: matching your practice to the firm's published criteria instead of running generic case drills. Build six supply chain and cost cases, drill estimation out loud, and write your fit stories against the seven values. Do that and you will walk into the founder round as the candidate who clearly did the work.

 

Frequently Asked Questions

 

How many rounds are in the Integration Consulting interview?

 

Integration Consulting lists five stages: application, aptitude test, first round interview, second round interview, and a final assessment day. Because the second round contains two separate sessions, most candidates experience four or five actual conversations. London candidates often describe the process as three interview rounds rather than five stages.

 

Does Integration Consulting do case interviews?

 

Yes. Integration Consulting uses case interviews in the second round and sometimes gives a shorter problem or market sizing question in the first round. The firm states that its cases replicate real consulting engagements and are usually based on a project the interviewer worked on for a client.

 

How long does the Integration Consulting hiring process take?

 

Glassdoor data from 87 interview reports puts the average at 34 days from first contact to a decision, as of August 2026. Analyst level roles in Brazil can run considerably longer. Intern processes are the fastest, sometimes wrapping up in a single day.

 

What is the Integration Consulting aptitude test?

 

It is an online or offline assessment covering numerical reasoning, verbal reasoning, and problem solving. It sits between your application and your first interview, so passing it is a prerequisite for meeting anyone at the firm. Some candidates also report a personality questionnaire at this stage.

 

Is Integration Consulting a good firm to work for?

 

Employees rate the firm 4.5 out of 5 on Glassdoor, and 90% say they would recommend it to a friend. Reviewers consistently point to the culture, early responsibility, and frequent feedback. The trade off is a smaller brand than the largest strategy firms, which matters if you are optimizing purely for exit options.

 

Do you need to speak Portuguese to work at Integration Consulting?

 

Not for the London, Chicago, or Munich offices. Portuguese helps considerably in Sao Paulo, and Spanish helps in Buenos Aires, Mexico City, and Santiago. Working English is expected everywhere, and at least one candidate reported having part of a Sao Paulo interview conducted in English to assess communication.
