Stax Internship 2027–2028: Programs, Deadlines & How to Apply

Last updated: September 2026

Stax is a ~300-person boutique, and boutiques do not publish applicant volumes. But the math is clear: a firm this small, with a client list covering nearly 70% of the PEI 300, fills its intern class from roughly 20 target schools and expects every candidate to survive a 2-hour Excel case study that most consulting firms do not even attempt. You apply during fall 2026, you intern in summer 2027. The firm recruits on a rolling basis through campus events and its Trakstar portal, and the Chicago summer internship and Boston co-op are the two entry points. With a 4.1/5 Glassdoor rating from 178 reviews, 82% of employees recommending the firm, and full-time Associate Consultant compensation reaching $85,000–$90,000 base plus bonus, the opportunity is real but the window is narrow.

Quick Facts

Two things set Stax apart: the PE-only focus (nearly 70% of the PEI 300 are clients) and the 2-hour Excel case study in the final round. Rolling review means the class fills progressively. Apply within the first two weeks of fall recruiting for the best odds.

Externships are short, remote professional experience programs where you finish a real project with a real company. The Yinan Zhao Investing & Financial Modeling Externship and the HP Tech Ventures Deal Sourcing Externship build exactly the Excel modeling and investment analysis skills Stax tests in its interview process.

What Is a Stax Internship?

A Stax internship is an 8–10 week summer placement (or a 6-month co-op through Northeastern) that puts students on live commercial due diligence engagements for private equity clients at a global strategy consulting firm with ~300 employees. Grant Thornton Stax, as it is now formally known after the September 2025 acquisition by Grant Thornton Advisors LLC, specializes in buy-side due diligence, growth strategy, value creation, and exit planning for PE firms, PE-backed companies, hedge funds, and investment banks. The firm was founded in 1994 by Rafi Musher in Boston and operates from offices in Boston (HQ), Chicago, New York, London, and Colombo, Sri Lanka. Stax was named one of the Top 50 Consulting Firms of 2026 by The Consulting Report and one of the Top 50 Best Consulting Firms to Work For by Vault in 2024. Interns work as Associate Consultants on lean case teams alongside Managing Directors, gaining direct PE deal exposure from day one.

When Do Stax Internship Applications Open for 2027–2028?

Stax is a boutique firm that does not publish hard application deadlines the way MBB or Big 4 firms do. The firm recruits on a rolling, office-specific basis, primarily through campus events at roughly 20 target schools during the fall semester. For summer 2027, expect recruiting activity between September and November 2026, with interviews running through early 2027. The Chicago office hires summer interns from schools including Notre Dame, Northwestern, Illinois, and Chicago; the Boston office runs its co-op through Northeastern's cooperative education calendar. The Stax Academy in Colombo, Sri Lanka, is a separate 6-month program with an October 30, 2026 deadline for the January 2027 intake.

How to read this page: our dates come from tracking previous recruiting cycles and daily posting data. Treat them as informed estimates based on historical patterns, not confirmed dates. The company's official careers page is always the most current source. If a role is posted there, go by that, even if this page suggests the window hasn't opened yet.

Why You Must Apply the Week Applications Open

Stax has roughly 300 employees across five offices. The summer intern class in Chicago is small, and the Boston co-op hires one or two students per cycle through Northeastern. Rolling review rewards early applicants, and 60% of the firm's recruiting happens through campus events with a defined fall calendar. If you wait until January 2027 to apply for something that recruits in September 2026, the seats are already filled. The 2-hour Excel case study in the final round is the make-or-break element that most candidates underestimate. Practice under timed conditions before the window opens: 90 minutes with a dataset, then 30 minutes to build 3–5 slides. That exercise separates prepared candidates from everyone else.

Which Stax Internship Programs Should You Target?

Stax offers several early-career pathways, from a focused summer internship to a longer co-op and an international academy program. Which one to target depends on your academic timeline, location, and whether you want a short intensive or a deeper immersion.

See all openings on the Stax careers portal. The Chicago summer internship is the most accessible entry point for current students, while the Northeastern co-op suits candidates looking for a longer, deeper commitment.

What Are the Eligibility Requirements?

Stax has not published a rigid eligibility checklist, but patterns from recruiting sources and community data point to the following:

• Enrollment: currently enrolled in an undergraduate degree program in business, economics, finance, or a related field.

• GPA: no published minimum. Competitive candidates typically maintain a 3.5+ GPA based on the target school context and peer firm benchmarks.

• Work authorization: must be authorized to work in the United States. International students are not eligible per Vault's internship profile.

• Target schools: American University, Bentley, Boston College, Boston University, Brandeis, Brown, Colby, Dartmouth, Harvard, Howard, Northeastern, Northwestern, Princeton, Spelman, Tufts, University of Chicago, UIUC, University of Michigan, Notre Dame, and UPenn. Non-target candidates can apply but should network heavily before submitting.

• Skills: proficiency in Excel (explicitly tested in the interview), strong analytical and quantitative abilities, comfort with ambiguity, and interest in private equity and strategy consulting.

Does Stax Hire From Non-Target Schools?

Yes, but with a significant caveat. Management Consulted emphasizes that networking before applying is critical for non-target candidates. Stax is a boutique firm that recruits heavily from its ~20 target schools through campus events and info sessions. If your school is not on the list, the path involves proactive outreach: request informational interviews on LinkedIn, attend any open recruiting events, and demonstrate in your application that you understand Stax's PE-focused model and can articulate why the firm's commercial due diligence work specifically interests you. A finished financial modeling or strategy project on your resume speaks louder than a school name.

What Skills Does Stax Look For, and How Do You Build Them?

Stax sits at the intersection of strategy consulting and private equity deal work, and its intern hiring reflects that dual identity. The firm's interview process is the clearest signal of what it values: behavioral questions test consulting aptitude, PE-focused cases test investment thinking, and the distinctive 2-hour Excel case study tests whether you can actually build an analysis under pressure. Across consulting prep sources, Glassdoor interview reports, and the firm's own messaging, Excel proficiency and PE investment thinking appear in every description of what makes a successful Stax candidate.

What Is the Stax Application and Interview Process Like?

Stax's interview process is multi-round and typically takes about 11 days from initial application to final decision, per Glassdoor. The process is distinctive for its 2-hour Excel case study, which separates Stax from every other consulting firm:

1. Apply at stax.hire.trakstar.com or via LinkedIn. Network with Stax consultants through campus events, LinkedIn, and informational interviews before applying. This is critical for non-target candidates.

2. HR phone screen (20–30 minutes). A recruiter assesses background, communication skills, and motivation for consulting. Demonstrate knowledge of Stax's PE focus and service areas (CDD, value creation, exit planning). Expect: "Why consulting? Why Stax?"

3. First-round interviews (45 minutes each, 1 behavioral + 1 case). Behavioral questions include "Tell me about a time you used data to make a recommendation" and the distinctive "What company or industry would you invest in and why?" The case is PE-focused and collaborative.

4. Final round (3–4 hours total). Back-to-back interviews including the signature 2-hour Excel case study: receive a dataset, analyze it using PivotTables and formulas, build 3–5 PowerPoint slides, and present your recommendation to a panel. Plus additional behavioral and case interviews with more senior staff.

5. Partner chat (30 minutes, not always). A final culture-fit conversation with a partner or senior leader.

The Excel case study is the make-or-break round. Practice under timed conditions: give yourself 90 minutes with a dataset, build PivotTables and summary charts, then create 3–5 clean slides in 30 minutes. Lead with your recommendation, support with 2–3 data points, and end with risks and next steps. Our HireVue question guide with a free AI mock tool covers the behavioral-question format that precedes the case rounds.

What the Community Says

Stax is a boutique firm with ~300 employees, so community discussion is sparser than for MBB or Big 4 peers. The most relevant firsthand perspectives come from Northeastern co-op students and expert-network professionals who have worked with the firm.

How Do You Stand Out at a Boutique PE-Focused Firm?

Three moves, all executable before fall 2026. First, master the Excel case study. This is what separates Stax from every other consulting firm. Practice with real datasets under timed conditions: 90 minutes of analysis, then 30 minutes to build 3–5 slides. Master PivotTables, VLOOKUP, conditional formulas, and charting shortcuts. Second, prepare a PE investment thesis. Stax interviewers ask "What company or industry would you invest in and why?" and they expect a structured answer with market size, growth drivers, competitive dynamics, and risks framed within a 3–7 year PE hold period. Have a 60-second thesis ready that shows you think like an investor, not a student. Third, demonstrate that you understand the difference between PE-focused consulting and generalist strategy work. In your "Why Stax?" answer, reference the firm's CDD specialization, flat hierarchy, limited-travel model, and the Grant Thornton acquisition. Name specific service areas (value creation, exit planning) or industries (software, healthcare, industrials) that interest you. Generic "I like consulting" answers do not survive the screen at a firm where every project has an investment thesis behind it.

What Other Companies Should You Consider?

Stax competes for candidates with other strategy consulting firms that serve the PE advisory ecosystem, from healthcare-focused boutiques to global generalist platforms.

FAQ

Can I still apply for a summer 2026 Stax internship?

No. Summer 2026 internship positions at Stax have been filled. The next opportunity is the summer 2027 cycle. Stax recruits on a rolling basis through its target schools, so begin networking with Stax consultants and monitoring the firm's careers portal at stax.hire.trakstar.com during fall 2026 to position yourself for the next intake.

When do Stax internship applications open for summer 2027?

Stax does not publish fixed application deadlines like MBB firms. The firm recruits on a rolling, office-specific basis, primarily through campus events at target schools during the fall semester. For summer 2027 positions, expect recruiting activity between September and November 2026. Monitor the Stax careers portal and attend any campus information sessions or networking events.

What is the Stax Excel case study and how should I prepare?

The Excel case study is a two-hour exercise in the final round where you receive a dataset, analyze it using PivotTables and formulas, build three to five PowerPoint slides with your findings, and present a recommendation to a panel. Practice under timed conditions with real datasets. Master PivotTables, VLOOKUP, conditional formulas, and Excel charting shortcuts. Lead with your recommendation and support with data.

How much does a Stax internship pay?

Stax does not publish intern-specific compensation. Full-time Associate Consultants earn a base salary of approximately eighty-five to ninety thousand dollars per year with bonuses bringing total compensation to roughly one hundred five thousand dollars. Prorating from the base salary, a ten-week summer intern would earn approximately sixteen to seventeen thousand dollars for the program.

Does Stax sponsor visas for international student interns?

No. According to Vault's internship profile, international students are not eligible for Stax's internship program. Candidates must be authorized to work in the United States. Policies may evolve following the Grant Thornton acquisition, so international students should confirm directly with the Stax recruiting team.

What is the difference between the Stax co-op and the summer internship?

The Boston office runs a co-op program through Northeastern University lasting approximately six months, integrated into Northeastern's cooperative education calendar. The Chicago office runs a shorter summer internship of roughly eight to ten weeks, recruiting from schools like Notre Dame, Northwestern, and the University of Chicago. Both offer hands-on consulting work on live PE client engagements.

What kind of case interviews does Stax give?

Stax cases are PE-focused rather than generalist strategy. Expect scenarios about whether a PE firm should invest in a target company, how to size a market for an acquisition, or how a portfolio company can accelerate growth. Cases are collaborative and somewhat interviewer-led with data exhibits provided during the discussion. Prepare using PE due diligence frameworks covering market attractiveness, competitive position, and financial returns.

Does Stax hire from non-target schools?

Yes, but networking is critical. Stax recruits heavily from roughly twenty target schools including Harvard, Northwestern, Notre Dame, Michigan, and Northeastern. Non-target candidates can and do get hired, but Management Consulted strongly recommends proactive networking: request informational interviews, attend open recruiting events, and demonstrate deep knowledge of Stax's PE-focused model in your application.

Stax's small intern class fills on a rolling basis once fall recruiting begins. Spend the runway building proof: a remote Externship turns "interested in PE consulting" into a finished financial analysis project a fall 2026 application can point at.
