Key Takeaways

 

The Elixirr interview rewards candidates who pair genuine commercial curiosity with a clear reason for choosing a challenger consultancy over a larger firm.

 

  • Elixirr runs a five-stage process: application, a 15-minute first interview, an assessment center, a final two-interview round, then an offer

 

  • The first interview is short and fit-focused, built around why consulting, why Elixirr, and why you

 

  • The assessment center combines a group case study with an individual presentation task and plenty of networking

 

  • Cases are commercial and practical rather than heavily quantitative, so structure and judgment matter more than speed

 

  • Glassdoor rates interview difficulty around 2.8 out of 5, with hiring taking roughly six to nine weeks

 

  • Your single biggest differentiator is a specific, well-researched answer to why Elixirr rather than a bigger name

 

What Is the Elixirr Interview Process?

 

The Elixirr interview process has five stages: an online application, a 15-minute first-stage interview with the talent team, an assessment center with group and individual tasks, a final round of two interviews with senior leaders, and an offer decision. Graduate and analyst candidates almost always go through an assessment center, while experienced hires follow a slightly different path centered on a prepared case study.

 

  1. Apply: submit your CV, an optional cover letter, and answers to a few application questions

  2. First-stage interview: a 15-minute call with the talent team covering skills, behavioral, and competency questions

  3. Assessment center: group activities, a case study, and an individual presentation task in front of Elixirr employees

  4. Final-stage interview: two separate interviews, one with a Consulting Principal and one with the Talent Acquisition Principal

  5. Offer: a decision and offer if you succeed in the final round

 

One quick point of confusion is worth clearing up first. Searches for "Elixirr" with two r's point to the challenger consultancy founded in London in 2009, not the Elixir programming language, so this guide is about the consulting firm and its hiring process.

 

Experienced hires see a different sequence. You start with a conversation with the talent team, then prepare a case study and present it to a Manager, then move to a Principal interview, and finally a Partner interview.

 

How Hard Is It to Get Into Elixirr?

 

Elixirr is moderately hard to get into, with Glassdoor candidates rating interview difficulty around 2.8 out of 5 based on dozens of submitted reviews. That sits clearly below the difficulty of an MBB case interview, but the bar is real because the firm screens for commercial instinct and culture fit as much as raw analytics.

 

The bigger challenge is stamina across the funnel. You have to perform in a fit screen, a group setting, an individual presentation, and two senior interviews, and a stumble in any one can end the process.

 

Timelines run long for graduates. Glassdoor puts the average hiring process at roughly 44 days across all roles, and analyst timelines stretch further because assessment centers cluster around September each year. In my experience coaching candidates into boutique firms, the people who get offers treat the gaps between rounds as prep time rather than waiting passively.

 

What Happens in the First-Stage Elixirr Interview?

 

The first-stage Elixirr interview is a 15-minute call with a member of the talent team that blends skills, behavioral, and competency questions. It is short, conversational, and built mainly to test three things: why consulting, why Elixirr, and why you.

 

Do not let the length fool you. Fifteen minutes is barely enough time to make three crisp points, so every answer needs to be tight and rehearsed rather than rambling.

 

Expect classic fit interview prompts like "tell me about yourself," "why do you want to do consulting," and "why Elixirr specifically." You will also get a short window to ask your own questions, so prepare two or three that show you have researched the firm.

 

This stage is where polished storytelling pays off. If you want a structured way to answer behavioral and fit questions, my fit interview course covers 98% of the questions you are likely to face in a few hours.

 

What Should You Expect at the Elixirr Assessment Center?

 

The Elixirr assessment center is a half-day event built around group activities, a case study, and an individual presentation task, with a networking lunch in the middle. You work through case materials with other candidates and then present your thinking, while Elixirr employees observe how you reason, collaborate, and communicate.

 

The group exercise is where most candidates trip up. The firm is watching whether you push the discussion forward without steamrolling others, so the same instincts that win a group case interview apply here.

 

There are a few behaviors that consistently score well in the group setting.

 

  • Structure early: propose a way to break the problem into parts before the group dives into details

 

  • Bring others in: ask quieter candidates for their view, since assessors reward inclusive teamwork

 

  • Track time: keep the group moving toward a recommendation rather than getting lost in one point

 

  • Land a view: make sure the group reaches a clear answer and that you helped get it there

 

The individual presentation rewards clarity above all. Treat it like a real client readout: open with your answer, support it with two or three reasons, and the same habits that make a strong case interview presentation will carry you here. Current analysts say the single best preparation is running a few practice cases beforehand so the format feels familiar.

 

How Does the Elixirr Case Interview Work?

 

Elixirr case interviews are commercial and practical rather than heavily quantitative, focused on whether you can break a real business problem into sensible parts and reach a defensible answer. One reported example asks you to identify the three highest costs for an airline and explain how you would reduce them.

 

Here is how I would structure that case. Start by naming the major cost buckets, then prioritize the three largest, then attack each with a specific lever.

 

Example: for an airline, the three biggest costs are usually fuel, labor, and aircraft ownership plus maintenance. Let's say fuel is the largest at roughly 30% of operating costs, so you might lower it through fuel hedging, more fuel-efficient aircraft, and route optimization.

 

For labor, you could focus on crew scheduling efficiency and productivity rather than blunt headcount cuts. For aircraft costs, you might improve fleet utilization and renegotiate maintenance contracts, then close with a clear recommendation on which lever to pull first.

 

You will not need advanced math, but you should still run clean arithmetic without a calculator. Drilling case interview math until percentages and quick estimates feel automatic frees up your attention for the actual business judgment.

 

Solid case interview frameworks give you a starting structure, and basic market sizing skills help when a case asks you to estimate a market. If you want to get case-ready fast, my case interview course can take you to a top 10% candidate in about 7 days.

 

What Questions Does Elixirr Ask in the Final Round?

 

The final Elixirr round is two separate interviews, one with a Consulting Principal who probes your problem-solving and one with the Talent Acquisition Principal who pressure-tests your fit and motivation. Experienced hires instead face a Principal interview followed by a Partner interview after presenting their prepared case.

 

The fit interviews here go deeper than the first screen. Expect personality-driven questions about how you work, how you handle setbacks, and what you want from your career, so prepare specific stories rather than generic claims.

 

A few questions come up again and again at this stage.

 

  • Why Elixirr rather than a larger consulting firm

 

  • Tell me about a time you led a team or drove a result

 

  • What companies or industries are you following right now and why

 

  • Where do you want your career to be in five years

 

That third question matters more than it looks. Several candidates report a take-home or discussion built around companies you find interesting, so walk in with a point of view on two or three businesses you genuinely follow.

 

How Should You Answer "Why Elixirr?"

 

The strongest "why Elixirr" answers connect the firm's challenger identity to a specific reason it fits how you want to work. Elixirr brands itself as the challenger consultancy, founded in London in 2009 to do things differently from the large incumbents, with consultants who own equity and help build the business.

 

Ground your answer in real facts about the firm. Elixirr listed on AIM in 2020, moved to the Main Market of the London Stock Exchange in 2025, and reported revenue of £111.3 million for FY 2024, up 30% on the prior year.

 

Then make it personal. Maybe you want broad exposure across strategy, digital, and data early in your career, or you want the ownership culture that comes with the firm's employee share scheme, where over 80% of consulting staff participate. Whatever you choose, tie it to a concrete experience of your own so the answer cannot be copied by the next candidate.

 

How Much Does Elixirr Pay?

 

Elixirr pay rises steeply with seniority, from around £35,500 for an Analyst to roughly £150,000 for a Principal in the UK. The figures below come from Glassdoor UK data as of June 2026, based on hundreds of submitted salaries, and are useful context as you weigh the offer.

Keep in mind that Elixirr layers an equity scheme on top of base pay, which is central to its ownership culture. That share component is part of why the firm pitches itself on building wealth alongside the business rather than competing purely on headline salary.

 

How Do You Prepare for the Elixirr Interview?

 

Tip #1: Build three sharp fit stories before anything else

 

The first screen and both final interviews lean heavily on fit, so your stories carry more weight here than your math. Prepare tight answers for why consulting, why Elixirr, and why you, each backed by a specific example.

 

Tip #2: Research Elixirr like a client

 

Know the firm's story cold: the challenger positioning, the 2020 AIM listing, the 2025 move to the Main Market, and recent acquisitions. As one of the more distinctive boutique consulting firms, Elixirr expects you to know why it is different.

 

Tip #3: Practice cases out loud, not just on paper

 

The assessment center and experienced-hire path both require you to present, so silent practice is not enough. Run timed case interview reps with a partner and narrate your structure as you go.

 

Tip #4: Prepare a view on companies you follow

 

Elixirr candidates repeatedly get asked which businesses interest them, sometimes as a take-home prompt. Walk in with two or three companies you can discuss with genuine opinions about their strategy.

 

Tip #5: Sharpen your CV and applications

 

The process starts with your CV and screening questions, and a weak application ends things before you ever interview. A focused consulting resume that highlights impact and leadership gets you to the first call.

 

Tip #6: Come ready with smart questions

 

Every stage gives you time to ask questions, and thoughtful ones signal real interest. Have a few strong questions to ask that go beyond what is on the website.

 

Preparing for the Elixirr interview comes down to one priority above the rest: pair a well-researched reason for choosing a challenger consultancy with enough case practice to present clearly under pressure. Nail those two things and you put yourself ahead of most of the field.

 

Frequently Asked Questions

 

Is the Elixirr interview hard?

 

The Elixirr interview is moderately difficult, with Glassdoor candidates rating it around 2.8 out of 5. That is below the difficulty you would expect at McKinsey, BCG, or Bain. The challenge comes from the breadth of the process rather than brutal case math, since you are tested on fit, a group case, a presentation, and two final interviews.

 

How long does the Elixirr hiring process take?

 

The Elixirr hiring process usually takes about six to nine weeks from application to offer, though Glassdoor puts the average near 44 days across all roles. Graduate timelines run longer because assessment centers cluster around September. Experienced hires often move faster, sometimes finishing in two to four weeks.

 

Does Elixirr ask case interviews?

 

Yes. Elixirr uses case studies at the assessment center and asks experienced hires to prepare and present a case to a Manager. The cases lean commercial and practical, for example identifying the three highest costs for an airline. You should still be comfortable structuring a problem and running clean mental math.

 

What is the Elixirr assessment center like?

 

The Elixirr assessment center is a half-day event with group activities, a case study, and an individual presentation task. You work through materials with other candidates and present to a panel of Elixirr employees. There is usually a networking lunch where you meet consultants, and the firm openly weighs how well you connect with the team.

 

Why do you want to work at Elixirr?

 

Tie your answer to Elixirr's identity as the challenger consultancy: a smaller, entrepreneurial firm where consultants own equity and build the business rather than follow a fixed methodology. Reference its growth, its 2025 move to the Main Market of the London Stock Exchange, and its acquisitions. The best answers link that culture to a specific reason it fits you.

 

What kind of firm is Elixirr?

 

Elixirr is a global management consulting firm founded in London in 2009 that calls itself the challenger consultancy. It works across strategy, digital, data, AI, and transformation, and reported revenue of £111.3 million for FY 2024. The firm listed on AIM in 2020 and moved to the Main Market of the London Stock Exchange in 2025.
