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

Last updated: August 2026

Liberty Mutual's intern class runs to more than 400 people across nine tracks, and the company has won Handshake's Early Talent Award six times. But the timing is what makes this moment urgent: last cycle's earliest internship requisition (TechStart) was created on 14 August 2025, and as of mid-August 2026, both of Liberty Mutual's ATS boards are still empty of summer-2027 intern postings. On last year's calendar, the wave is due within days. One door is already open: Comparion's academic-year sales internship for 2026/27 is live right now.

Quick Facts

The summer-2027 corporate internship hasn't opened yet, but on last cycle's timing it's due within days. TechStart's requisition was created 14 August 2025. Liberty Mutual reviews on a rolling basis, warns that postings can be pulled once enough candidates apply, and extends offers as it goes. There's no published deadline; the risk is the posting disappearing, not a date passing.

Externships are short, remote programs where you finish a real project with a real company. The Yinan Zhao Investing & Financial Modeling Externship builds the analytical and modeling evidence an actuarial or finance application needs, and the Attronica Financial Planning Analysis Externship builds the risk-assessment vocabulary the underwriting tracks test for.

What Is a Liberty Mutual Internship?

A Liberty Mutual internship is a paid, 11-week summer placement across nine undergraduate tracks at a Fortune 95 property-and-casualty insurer with $50.5 billion in revenue and 40,000-plus employees in 27 countries. Liberty Mutual is a mutual company, policyholder-owned rather than shareholder-owned, and the 9th largest global P&C insurer.

And the internship feeds named development programs (Actuarial Development, Underwriting Training, Analyst Development and others). Liberty Mutual calls it "one of the best paths to full-time employment".

When Do Liberty Mutual Internship Applications Open for 2027–2028?

Liberty Mutual doesn't publish an opening date or a closing deadline, so you read the calendar from its behavior, which is very consistent. The TechStart internship requisition for summer 2026 was created on 14 August 2025; the actuarial requisition was public by late August; claims didn't appear until December. The full wave rolls out over about three and a half months, and every requisition is rolling.

So for summer 2027, the earliest postings are expected from mid-August 2026, roughly nine and a half months before a June start.

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

Liberty Mutual answers the deadline question inside its own requisitions: "We encourage interested candidates to apply promptly, as the role may be unposted once we've received a sufficient number of candidates. We conduct interviews and extend offers on a rolling basis." That sentence appeared in the actuarial, graduate data science and analyst development postings, three different tracks. No req states a hard deadline; the full 25-requisition corpus was searched for "deadline," "apply by," "closing date" and "applications close" with zero hits.

So the risk isn't missing a date. The risk is the posting disappearing.

And a week-one application faces the lowest competition it will ever see.

Which Liberty Mutual Internship Programs Should You Target?

Liberty Mutual names nine undergraduate tracks on its own site, plus graduate and co-op options. Which track you pick determines your skill bar entirely: underwriting and claims test negotiation and customer service, TechStart tests Java, and data science tests Python and R. The common core across all of them is analytical reasoning and communication.

See all nine tracks on the undergraduate programs page. Graduate students should look at the Graduate Data Science internship ($45–$60/hr, the premium track on both pay and PTO), and the Solaria Labs and Cybersecurity co-ops run six months with two intakes a year.

What Are the Eligibility Requirements?

Eligibility varies by track more than usual here, and the variance is the useful fact:

• GPA: 3.0 for most tracks, but it's a minimum for some (underwriting commercial lines) and preferred for others (actuarial, claims, Solaria co-ops). TechStart, Graduate Data Science and Property Risk Engineering name no number, asking only for "a proven track record of academic success."

• Class year: at least one semester remaining after the internship summer. Graduate Data Science requires a Master's or PhD in a quantitative field.

• Work authorization: most reqs (12 of 23) require permanent US work authorization. Three technology roles require full authorization without restrictions. Two of the newest reqs explicitly exclude future sponsorship, including CPT/OPT. Check the specific posting.

• Actuarial exams: preferred but not required, identically in both the 2025 and 2026 cycles. No exam count is specified.

• Experience: 0–2 years of professional experience (13 of 23 reqs).

Is the GPA a Hard Cutoff?

It depends on the track. Underwriting Commercial Lines states a minimum 3.0 GPA. Claims, the Solaria Labs co-ops and (since the 2026 cycle) Actuarial say 3.0 preferred. TechStart, Graduate Data Science and Property Risk Engineering name no number. So a 2.9 is disqualifying for some underwriting reqs and explicitly not disqualifying for others. Check the specific requisition before you rule yourself out.

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

Twenty-three Liberty Mutual corporate intern requisitions from the 2025 and 2026 cycles were read in full, and the skill map splits cleanly by track. Analytical reasoning and interpersonal skills run across nearly everything.

But below that shared core the tracks diverge completely: Java appears only in TechStart and Solaria engineering reqs, R and SAS appear only in data science, Excel appears only in finance, and negotiation appears in every underwriting and claims req and nowhere else.

So what Liberty Mutual wants from you depends almost entirely on which track you pick.

Build These Skills Before You Apply

And every bar in the chart maps to a remote Externship that ends in a finished company project.

How close is the overlap? The Yinan Zhao deliverable is investment analysis in the actuarial posting's own vocabulary, and the Attronica project builds the risk-assessment reasoning all four underwriting arms test for.

What Is the Liberty Mutual Application and Interview Process Like?

Liberty Mutual's intern hiring process, assembled from its own careers resources and community reports:

1. Apply on the campus board, not the main corporate board. Intern reqs appear only on the iCIMS campus site; the main Eightfold board (219 open roles) carries none of them. One application per requisition; multi-location reqs are a single application.

2. Join the Undergraduate Talent Network before the wave opens. Given the rolling process, this is the single highest-value pre-application action.

3. Recruiter or initial screen. Community reports describe a recruiter call before the substantive round, but no official step count is published.

4. Technical or behavioral interview, depending on track. TechStart candidates report a technical round with two coding questions (described as straightforward, not an algorithmic-difficulty test). Actuarial candidates report a behavioral-weighted panel, roughly a 30-minute introduction followed by an hour-long behavioral interview (community-reported).

5. Offer, extended on a rolling basis. Community reports place TechStart offers as early as November for the following summer.

Liberty Mutual's own interview resources page has first-party prep materials.

And no HireVue or online assessment could be confirmed for Liberty Mutual specifically.

What Students on Reddit Say

Three threads, from students who went through the process.

How Do You Stand Out in a 400-Person Intern Class?

Four moves, starting with the calendar. Join the Undergraduate Talent Network now, and apply the day the posting appears. The reqs say outright that they may be pulled once enough candidates apply. Second, pick your track before you apply and match your evidence to it. The skill map is track-partitioned: Java for TechStart, R and SAS for data science, Excel for finance, negotiation for underwriting and claims.

So a generic application matches no track well. Third, if you're targeting actuarial: sit an exam even though it isn't required. The req says exams are preferred but not required, which makes a sitting a cheap, unambiguous differentiator.

And fourth, for underwriting: say explicitly that you'll pursue the designations. All four underwriting arms require willingness to complete professional designations, and most applicants won't address it.

FAQ

Can I still apply for a summer 2026 Liberty Mutual internship?

No. The summer-2026 requisitions are closed. Liberty Mutual's campus board returns "no longer open" for every one of them.

But the next cycle is summer 2027, and those postings are expected from late August 2026 onward. One thing is open now: Comparion's academic-year sales internship for 2026/27.

When do Liberty Mutual internship applications open for summer 2027?

Expect mid-August through October 2026, starting essentially now. The summer-2026 TechStart requisition was created on 14 August 2025, actuarial by late August, and claims not until December. Applications open roughly nine and a half months before the internship starts, and the wave rolls out over about three and a half months.

Is the Liberty Mutual internship rolling?

Yes. The requisitions say so directly: Liberty Mutual encourages candidates to apply promptly because a role may be unposted once enough applications arrive, and it interviews and extends offers on a rolling basis. No requisition states a deadline, so the risk is the posting disappearing, not a date passing.

What GPA do you need for a Liberty Mutual internship?

Usually 3.0, but it depends on the track. Underwriting Commercial Lines states a minimum 3.0. Claims, the Solaria Labs co-ops and the actuarial program say 3.0 preferred. TechStart, Graduate Data Science and Property Risk Engineering name no number at all, asking instead for a proven track record of academic success.

Do you need actuarial exams to get the Liberty Mutual actuarial internship?

No. The requisition says actuarial exam sittings or passing scores are preferred but not required, identically in both the 2025 and 2026 cycles. No exam count is specified anywhere.

But sitting one is a genuine differentiator rather than a barrier, which makes it a cheap way to stand out.

How much does a Liberty Mutual internship pay?

Liberty Mutual publishes hourly ranges on its requisitions. Summer 2026: graduate data science $45–$60, technology (TechStart) $30–$38, surety underwriting $26.50–$28.50, actuarial $24.50–$31, finance $24.50–$26.50, analytics $23.50–$26.50, claims $22.50–$24.50. Every intern role accrues 15 flexible time-off days.

Does Liberty Mutual sponsor visas for interns?

Mostly no, and it varies by requisition. Twelve of the requisitions we read require permanent US work authorization. Three technology roles require full authorization without restrictions. Two of the newest reqs state that Liberty Mutual won't sponsor employment visas, including for candidates on CPT or OPT. Check the specific posting.

Do Liberty Mutual interns get full-time offers?

Liberty Mutual says internships are one of the best paths to full-time employment but publishes no conversion rate, so treat any percentage you see elsewhere as unsourced.

But structurally the pipeline is real: every track feeds a named development program, such as the Actuarial Development Program and the Underwriting Training Program.

There's no deadline to circle, just rolling review that starts the day each posting appears and can end the day Liberty Mutual has enough candidates. The corporate summer-2027 wave is expected to open within days. Join the Undergraduate Talent Network now and apply in week one. Spend the remaining runway on proof: a remote Externship turns "strong analytical skills" into a finished project a day-one application can point at.
