Roamly Call Center: An online travel platform's overloaded national call center
A digital operations transformation case with a driver-tree calculation, the kind of structured problem solving and quantitative analysis Capgemini Invent says its case interview assesses. The full version is TravelLine Call Center Optimization, a library case of ours, not a Capgemini Invent case. Capgemini Invent (opens in a new tab), read
1Step 1: Read the case
Roamly, an online travel booking platform, has closed its twelve regional service offices and moved all of its customers to one national call center. Customers now wait more than 20 minutes on the phone and satisfaction is falling fast. The CEO wants to know why, and what to do about it.
2Step 2: Ask clarifying questions
Open a question to hear the interviewer's answer.
What changed, and why was it done?
Interviewer: Service moved from twelve regional offices to one national center over about a year, to cut cost and make service more consistent.
How many customers are there, and how often do they call?
Interviewer: About 780,000 active customers, all migrated now, and each contacts the center 2.5 times a year on average.
How long does a call take, and how many agents are there?
Interviewer: Talk time averages 210 seconds plus 90 seconds of wrap-up. There are 45 trained agents.
How much of an agent's week goes on calls?
Interviewer: Agents work 40 hours, but about 78% of that is working time after breaks, meetings and admin, and about 55% of that is spent on calls. For this practice case, treat the 55% as covering talk time and wrap-up together.
Can the company simply hire more agents?
Interviewer: Training takes eight weeks and the hiring budget is limited. There is no data yet on why people call or on self-service options.
What does the CEO want from us?
Interviewer: A diagnosis of the root cause and a recommendation. There is no wait-time target and no deadline.
3Step 3: Structure your answer
Take two minutes. Lay out how you would find out why the center is overwhelmed and what to do, then say where you would start.
2:00
Show what a strong structure covers
Plays the problem back: one national center, 780,000 customers, 45 agents, waits of 20 minutes and rising, and a request to diagnose and recommend.
Builds the diagnosis as demand against capacity: calls per week on one side, what an agent can handle per week on the other, and the gap between them.
Breaks demand into customers, contacts per customer and seasonality, and capacity into agents, working hours, time on calls and handling time per call.
Names the levers in three groups: lower demand (self-service, fixing why people call), raise capacity per agent (tools, shorter wrap-up) and add agents (hiring and its lead time).
Flags constraints early: eight weeks to train, a limited budget and no data yet on call reasons.
Says what it would do first and in what order, for example size the gap, then pilot the quick levers while hiring starts.
4Step 4: The interviewer's next question
Using the numbers you have, how many agents does the center need to handle an average week?
Show what a strong answer does
Demand: 780,000 × 2.5 = 1.95 million calls a year, or 37,500 a week. Capacity: 40 hours × 78% × 55% is about 17 handling hours, and at 300 seconds a call that is about 206 calls per agent per week. 37,500 divided by 206 is about 182 agents against 45 today. A strong answer says the gap out loud, notes this is an average week, so the summer peak needs more, and moves to the levers.

Capgemini Invent's description of itself and its four teams, with the note that the steps depend on the country and role.
Worked: Example problem: an automaker and electric and self-driving vehicles, in Capgemini Invent's six case tips
An automotive client asks what it should do about electric and self-driving vehicles. Capgemini Invent's page lists four asks: estimate the market opportunity in North America, say how the client could position itself against competitors, name the value it would offer customers and recommend which customers to target and how to find out. Read the official case (opens in a new tab)(read )
How you might work it is ours, not Capgemini Invent's answer key.
1
Take your time
Before you speak, write the four asks as four boxes and a one-line goal: where to play in electric and self-driving vehicles, and how big and attractive it is. Say how you will order them: market size first, then competitors, then customer value, then targets.
2
Understand the question and clarify
Ask what the client makes and sells today, what the decision is (enter, grow or invest), the time frame, and whether electric and self-driving are one market or two. Ask what the client already knows about its customers, since the last ask is how to find that out.
3
Take notes throughout
Keep one page per ask: your assumptions, the numbers you computed and the questions you still have. The notes are what lets you summarize in step four without starting over.
4
Size the market, then position and choose customers
Size each vehicle type separately: new vehicles sold a year, times the share that is electric or self-driving, times the price, with a second route from households as a cross-check. Then compare competitors on the few things buyers pay for, name the customer value in one sentence and pick the segments where the client's strengths and the demand overlap.
5
Summarize the key issues and findings
Give three points: the size of the opportunity and the assumption most likely to be wrong, where the client can win against competitors, and which customers to go after first.
6
State your recommendation, then next steps and impact
Recommend one move, name the main risk and how you would reduce it (the page lists risks and mitigation as a skill), then close with next steps and the result you expect, such as testing the target segment with customer interviews before committing capital.

The Capgemini Invent interview process, and what trains each step
1
Application and one pathway (UK graduates)
For the UK Accelerate graduate programme you submit a CV, a cover letter and an online application with motivational questions, and can apply for only one role per recruitment season. Capgemini says applications are reviewed first come, first served, so apply early.
Successful UK applicants answer a series of questions on camera to show their passion for Capgemini Invent and the role; a demo with mock questions is available, and Capgemini says it does not review the demo answers.
Capgemini Invent describes a guided case interview of about 45 minutes that assesses critical thinking, problem-solving and communication style in a client situation, and strongly encourages every candidate to practise first. Its tips: take your time, clarify, take notes, summarize, state recommendations and outline next steps and expected impact.
The UK process ends in a half-day assessment centre with a group exercise, a 1:1 strengths-based interview, icebreakers and a short presentation about Capgemini Invent and your chosen pathway. Capgemini says candidates are not competing with each other and need to collaborate.
Phone and Teams interview with a case, onsite group case, final interview (Sweden)
Swedish graduates get an initial phone and Teams interview plus a case; a select group is then invited to a half-day visit in Sweden, Denmark or Finland to work a group case and present it to senior consultants, and those who progress meet a Capability Unit Manager or equivalent. Experienced hires typically have three interviews, with cases often used to test analytical skills.
Virtual interview, then an in-person round with a case study (Germany)
In Germany a preselection on your qualifications leads to a virtual interview on personal fit, which may include a case study; the in-person round at one of the offices covers your motivation and past achievements and ends with a subject-specific case study. Capgemini says the process has three interview rounds and that you get a first answer within ten working days of a complete application.
Missing from Capgemini Invent's pages: who leads the case, how the case is scored, whether Invent's US and global process includes a group case or assessment centre, group size and reading time, whether any online test is used, how long each round lasts outside the 45-minute case, and when offers are made.
12 Capgemini Invent-style interview questions
In our words, not Capgemini's, grouped by Capgemini Invent's six case tips and skills, plus the group exercise some countries use and the fit interview, with what a strong answer does.
Take your time and clarify (tips 1 and 2)
Capgemini Invent: take your time organizing your thoughts, and ask for clarification if you need it.
1A manufacturer wants to fit sensors to its factory machines to cut unplanned downtime. What do you play back before you start?
What a strong answer does: Restates the real decision (is the investment worth it, not how sensors work), fixes the scope of plants and machines, states one or two assumptions out loud and asks one or two questions before laying out a plan.
2A retailer's online orders ship late and returns are rising. Which two clarifying questions do you ask first, and why?
What a strong answer does: Asks where in the chain it breaks (picking, packing or carrier) and when it started, because each answer removes whole branches of the tree; it does not ask for everything at once.
Capgemini Invent lists analysis of both numbers and qualitative information among the skills it assesses.
3A call center takes 37,500 calls a week and one agent handles 200 calls a week. How many agents does it need?
What a strong answer does: Divides to 187.5, rounds up to 188, then says that is an average week with no slack, so a seasonal peak or an absence needs more, and asks what share of time is actually on calls.
4After a chatbot launch, a utility's service cost per contact fell 20% while contacts per customer rose 10%. Did the total service cost fall?
What a strong answer does: Multiplies the two changes, 0.8 times 1.1 is 0.88, so about 12% lower if the customer count is flat, and asks whether the cost per contact includes the chatbot's own running cost.
5Estimate how many electric cars are sold in North America each year.
What a strong answer does: Picks one route, such as total new vehicle sales times an electric share by segment, names a cross-check from households and vehicle life, and says which assumption it would test first.
Capgemini Invent lists thinking holistically, including identifying risks and mitigation tactics.
6You recommend moving a bank's reporting systems to a cloud platform. What are the three biggest risks, and how would you reduce each?
What a strong answer does: Names data security and regulation, disruption during the migration and cost or adoption overruns, and pairs each with a mitigation (controls and a regulator check, a staged cut-over with a rollback, and a budget with a stop point).
7The client's plan needs a new system live in six months; the delivery team says twelve. What do you recommend?
What a strong answer does: Gives a recommendation first, such as a phased launch with the must-have features at six months, then the trade-off, the main risk and the next step, and stops talking.
The UK assessment centre includes a group exercise and Sweden's onsite visit a group case presented to senior consultants.
8You are in a group of five reading the same materials, and you have two minutes before anyone speaks. What do you do?
What a strong answer does: Writes a short structure alone first, then offers it as a proposal ("here is one way to split this, what would you change?"), so the group gets direction without feeling led.
9Two teammates disagree about which market to enter. How do you help the group decide?
What a strong answer does: Restates both positions fairly, proposes two or three criteria the materials can settle, points to the data that decides it and moves the group to a recommendation before time runs out.
Personal fit (digital, virtual and in-person interviews)
Capgemini asks about your motivation, achievements and strengths, and in Germany often your thesis or project work.
10Why Capgemini Invent, and why this team or pathway?
What a strong answer does: Names something specific Capgemini Invent says about itself (its four teams, digital innovation and transformation) and ties it to something you have done, in under a minute.
11Tell me about a project where your team hit a problem and the plan changed.
What a strong answer does: Tells one short story with a moment of choice in it, what you did, the result and the lesson learned, the three things Capgemini's interview tips ask you to share.
12Walk me through your thesis or your last project, and what you would do differently.
What a strong answer does: Gives the question, the method and the one result in a minute, then a real lesson; in Germany Capgemini says technical questions usually follow thesis or project work.

A Capgemini Invent prep plan, day by day
The order follows Capgemini Invent's own pages; the timing is our suggestion.
Days 1 and 2
Read Capgemini Invent's own pages
Read the case interview section, its example problem and six tips, then your own country's recruitment page, and check your invitation for the format.
Time the four asks of the electric and self-driving vehicle example at about 45 minutes, using the six tips, then write a three-point summary and one recommendation with a next step.
With two or three friends, read one case pack silently, then discuss it for 30 minutes. Practise offering a structure as a proposal and bringing in the quiet person.
Prepare a specific Why Capgemini Invent answer, two or three stories with numbers in them and a one-minute walk through your thesis or last project, and say them out loud.
How do I prepare for the Capgemini Invent case interview?
Start with Capgemini Invent's own case interview page: it describes a guided case of about 45 minutes, gives one example problem (an automaker deciding what to do about electric and self-driving vehicles) and six tips, but no worked answer, so work the example out loud yourself. Then train what it names: a clear structure, numbers and qualitative analysis, explaining your thinking under pressure, and the big picture with risks and how to reduce them. On Road to Offer a free account includes 1 full AI-graded case, such as TravelLine Call Center Optimization, a digital and operations transformation case; the 8 practice cases for Capgemini Invent cover operations, technology and growth. Firm-style cases are practice cases written for Road to Offer or adapted from university consulting club casebooks, not the firm's own cases.
Where can I practice Capgemini Invent-style case interviews for free?
On Road to Offer, TravelLine Call Center Optimization is a digital operations transformation case you can run out loud with an AI interviewer or step by step; your first full case is free with a free account, no card. A worked case with a model answer for every question, Corvane Air Operations, is free to read with no account. Capgemini Invent's own page gives one example problem and six tips but no solution, and its page lists outside practice links. Firm-style cases are practice cases written for Road to Offer or adapted from university consulting club casebooks, not the firm's own cases.
What is Capgemini Invent's own case interview preparation, and how should I use it?
It is the case interview section of Capgemini Invent's students and graduates page, with four parts: what a case interview is (a client scenario worked in real time, guided, about 45 minutes), an example problem statement, six tips and three outside links for more practice. The example asks you to estimate the North American market for electric and self-driving vehicles, position the client against competitors, name the value it offers customers and say which customers to target. Treat it as a checklist, not a case with an answer: work the four asks out loud in about 45 minutes, using the six tips (take your time, clarify, take notes, summarize, recommend, outline next steps and expected impact).
How long is the Capgemini Invent case interview?
About 45 minutes, according to Capgemini Invent's students and graduates page, which calls the session guided. Candidates report 30 to 45 minute individual cases and, in some countries, a longer half-day or full-day assessment centre. Capgemini's UK, Swedish and Australian pages describe the assessment centre as a half day (UK, Sweden) or a full day (Australia), so check your own invitation.
Is the Capgemini Invent case interview candidate-led or interviewer-led?
Capgemini's page calls the case interview guided and does not say who leads, and candidate reports describe a candidate-led second round. Plan for both: open with your own structure and then say which branch you will start with, and also be ready to answer one directed question at a time with a number.
Does Capgemini Invent have a group case or an assessment centre?
In some countries. The UK graduate process ends in a half-day assessment centre with a group exercise and a 1:1 strengths-based interview; Sweden invites a select group to a half-day onsite visit to work a group case and present it to senior consultants; Australia invites graduates to a full-day assessment centre with interviews and case-solving exercises. Capgemini's German site says it deliberately forgoes an assessment center and uses personal conversations instead. Candidates report groups of four to six with a pack of materials; Capgemini's pages give no group size, so follow your invitation.
How many interview rounds does Capgemini Invent have?
It depends on the country. The UK graduate programme has three steps: an online application, a digital interview and a half-day assessment centre. Sweden has three stages for graduates: a phone and Teams interview with a case, a half-day onsite group case and a final interview. Germany says its process has three interview rounds. Experienced hires in Sweden and Australia typically have three interviews, and cases are often used to assess analytical skills.
Does Capgemini Invent have an online test?
Capgemini Invent's pages describe no test for its consulting roles. The UK graduate process has a digital interview, where you answer questions on camera, and Capgemini's UK recruitment page says the process may also include assessments or presentations depending on the role. Candidates report data exercises in some interviews. Road to Offer has no Capgemini Invent test simulator; the closest practice is our case math and chart drills.
Does Capgemini Invent ask market sizing questions?
Its own example does: the first ask in Capgemini Invent's example problem is to estimate the market size opportunity in North America for electric and self-driving vehicles. Expect an estimate to feed a decision, then positioning, customer value and target customers. Practise sizing with a clear route, a cross-check and a stated assumption you would test first.
What does the Capgemini Invent fit interview cover?
Capgemini's German pages say the in-person round covers why you apply, what motivates you and what you have achieved, and the UK assessment centre includes a 1:1 strengths-based interview. Capgemini's interview tips ask you to tell your story: how your experience fits the role, achievements, challenges you overcame and lessons learned, and to research the role and Capgemini's values. Prepare a specific answer on why Capgemini Invent and why your pathway or team, and two or three stories with numbers in them; Road to Offer's fit practice asks the questions with follow-up probes, 1 session free with a free account.
What kinds of cases does Capgemini Invent ask?
Capgemini's page shows one example, an automotive client deciding what to do about electric and self-driving vehicles, and gives no list of case types. Capgemini Invent describes itself as the home of digital innovation, design and transformation, with teams in customer experience and design, intelligent industry (engineering, supply chain and manufacturing), enterprise transformation and individual industries, so cases about technology, operations and transformation are a sensible thing to practise. Candidate reports add the usual strategy case types.
Can I apply to more than one Capgemini Invent role?
For the UK Accelerate graduate programme, no: Capgemini says candidates can apply for only one role per recruitment season (September to August) and should contact the team if another pathway seems a better fit during the process. Other countries and experienced-hire roles may differ, so check your own vacancy page.
