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

Last updated: September 2026

MassMutual is a Fortune 500 mutual life insurance company founded in 1851, managing over $800 billion in total assets under management and administration, with approximately $42 billion in annual revenue and around 10,000 employees. Its actuarial internship is one of the most respected in the life insurance sector, feeding directly into the Actuarial Development Program (ADP), a multi-year rotational pipeline with full SOA exam support. The company holds an AA+ financial strength rating from S&P and has paid dividends to policyholders every year since 1869. Applications for summer 2027 are expected to open around September–October 2026 based on prior-cycle patterns. MassMutual reviews on a rolling basis, so the actuarial and data science tracks fill early. With intern pay of approximately $25–$32/hr for actuarial roles on Glassdoor and a strong conversion pipeline, this is a top-tier opportunity for quantitative students.

What Is a MassMutual Internship?

A MassMutual internship is a paid, 10-week summer placement that puts college students into real roles across Actuarial, Finance, Technology, Data Science, Investment Management, and Marketing at a Fortune 500 mutual life insurance company managing over $800 billion in assets. Founded in 1851 in Springfield, Massachusetts, MassMutual is owned by its policyholders rather than public shareholders, which means long-term stability and less quarterly-earnings pressure. The actuarial internship is the flagship program, serving as the primary pipeline into MassMutual's Actuarial Development Program (ADP), a multi-year rotational program with full SOA exam support including study time, materials, and bonuses for each exam passed. Interns receive structured mentorship, networking with senior leaders including credentialed actuaries (FSA/MAAA), community service projects, and present a capstone project. MassMutual holds a 3.8/5 Glassdoor rating with actuarial intern reviews averaging 4.0–4.3/5.

When Do MassMutual Internship Applications Open for 2027–2028?

MassMutual is a mutual company, so it publishes less recruiting-calendar detail than publicly traded peers. Based on prior-cycle patterns, summer internship postings typically appear on the Workday portal in September–October for the following summer. The actuarial track is the most competitive and fills earliest, while technology and data science roles may remain open into the winter. For summer 2027, you should expect to apply in fall 2026, roughly 8–10 months before the June start, with rolling review that prioritizes early applicants. Springfield MA hosts the majority of actuarial interns, while the Boston office has grown as MassMutual's data science and technology hub.

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

MassMutual's actuarial internship is one of the most respected in the life insurance sector, and it serves as the primary pipeline into the Actuarial Development Program. That means the actuarial seats attract highly qualified candidates with multiple SOA exams, strong GPAs, and prior quantitative experience. Rolling review rewards the earliest applicants, and the actuarial class fills before the holiday break in most cycles. Do not wait until January 2027 to apply for something that posts in September or October 2026. Early application plus shown quantitative skills, including at least two SOA exams and a finished financial modeling or analytics project, is the formula. The mutual company structure means less turnover pressure and more deliberate hiring, which makes every seat that much more intentional.

Which MassMutual Internship Programs Should You Target?

MassMutual runs a multi-track summer internship program with approximately 100–150 interns across the company each summer. Which track to target depends on your academic background and whether you want the actuarial pipeline or a broader business role.

See all openings on the official MassMutual Workday portal. The actuarial internship is the most structured entry point, while technology and data science tracks suit candidates with strong programming backgrounds.

What Are the Eligibility Requirements?

MassMutual has published eligibility criteria in prior-cycle postings and career site guidance. Here is what to expect:

• Enrollment: current full-time undergraduate or graduate student pursuing a degree in a relevant field.

• GPA: 3.0 minimum preferred for most tracks; 3.2–3.5 preferred for actuarial and data science based on prior JD language.

• Actuarial track: actuarial science, mathematics, statistics, or related quantitative major; must have passed or be sitting for at least one SOA/CAS exam (Exam P/1 or FM/2); multiple exams preferred.

• Work authorization: no visa sponsorship available for internship positions. International students requiring sponsorship are excluded.

• Availability: full-time, 40 hours/week for the 10-week duration. On-site or hybrid at the designated location.

Does MassMutual Have a Hard GPA Cutoff?

The 3.0 minimum is stated as preferred, not as a hard cutoff, based on prior-cycle JD language. However, competitive tracks like actuarial and data science effectively require 3.2 or above because the applicant pool skews quantitatively strong. What matters more in practice is shown quantitative capability: SOA exam progress, Python or R proficiency, and a finished modeling or analytics project. If your GPA is below 3.2 but you have two SOA exams passed and a data project on GitHub, that evidence speaks louder.

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

MassMutual sits at the intersection of traditional life insurance and modern data science, and its intern hiring reflects that dual identity. Across prior-cycle job descriptions and program descriptions, the pattern is clear: actuarial and quantitative skills appear in every track, while communication and analytical thinking are baseline expectations. The company's investment in AI/ML and digital transformation means technology and data science tracks increasingly emphasize Python and cloud platforms alongside traditional actuarial tools like Excel, SAS, and VBA.

What Is the MassMutual Application and Interview Process Like?

MassMutual's hiring process for interns follows a standard insurance industry pattern, with some actuarial-specific elements:

1. Monitor the Workday portal starting September 2026. Navigate to massmutual.wd5.myworkdayjobs.com and search for "intern" or filter by student positions. Also check massmutual.com/careers/early-careers.

2. Apply online. Create a Workday profile, submit your resume and transcript, and complete application questions. Actuarial applicants should list SOA/CAS exams passed and scheduled.

3. Recruiter phone screen (weeks 1–2). A 20–30 minute call covering your motivation, work authorization, availability, and for actuarial candidates, exam progress and career interests.

4. Technical and behavioral interview(s) (weeks 2–4). Expect STAR-method behavioral questions plus technical questions relevant to your track. Actuarial candidates face questions on probability, statistics, and SOA exam content. Technology candidates may encounter coding challenges.

5. Hiring manager or team interview (weeks 4–6). Final round with the team you would join. May include a case study or analytical exercise for actuarial and data science tracks.

6. Background check and offer (weeks 6–8). Offers include details on compensation, Springfield or Boston placement, and start date.

The process is described by candidates as moderate difficulty and more behavioral than technical compared to consulting or tech firms. Actuarial candidates report that showing SOA exam progress and genuine interest in the life insurance industry matters more than LeetCode performance. Our HireVue question guide with a free AI mock tool covers the same behavioral-question pressure and format.

What the Community Says

The actuarial subreddit and broader finance communities discuss MassMutual regularly. Here is what candidates and early-career actuaries report.

How Do You Stand Out at a 175-Year-Old Mutual Life Insurer?

Three moves, all executable before fall 2026. First, pass at least two SOA exams before applying. MassMutual's actuarial JDs say one exam minimum, but the candidate pool at a top-tier life insurer skews competitive; having Exam P and Exam FM both passed signals commitment and gives you a concrete edge. Second, connect your skills to life insurance specifically. MassMutual's actuarial work centers on mortality, morbidity, and longevity risk. Reference specific life insurance concepts in your interview: mortality tables, lapse rates, policy reserves, or annuity pricing. Showing you understand the difference between life/health and P&C actuarial work demonstrates genuine interest. Third, highlight your Springfield willingness. Many candidates overlook MassMutual because Springfield is not Boston or New York. Frame this as a positive: lower cost of living means your compensation stretches further, the office is smaller and more collaborative, and you get direct access to credentialed actuaries (FSA/MAAA) who are less stretched across hundreds of interns.

FAQ

Can I still apply for a summer 2026 MassMutual internship?

No. The summer 2026 class started in June 2026 and those postings closed earlier in the year. The next open cycle is summer 2027: based on prior-cycle patterns, MassMutual posts summer internships around September to October 2026, so monitor the Workday portal now and apply in the first week postings appear.

How much do MassMutual interns get paid?

Actuarial interns earn approximately $25 to $32 per hour based on Glassdoor data. Technology and data science interns may earn $28 to $35 per hour. MassMutual also provides relocation assistance or a housing stipend for interns who need to move to Springfield, typically ranging from $2,000 to $4,000.

Where are MassMutual internships located?

Most internships are based at MassMutual headquarters in Springfield, Massachusetts. Some data science and technology roles are in Boston. The company operates a hybrid model with interns expected on-site multiple days per week. Springfield offers significantly lower cost of living than Boston or New York.

What departments offer MassMutual internships?

MassMutual offers internships across Actuarial, Finance, Technology and IT, Data Science, Investment Management through its Barings subsidiary, and Marketing and Communications. The actuarial track is the largest and most formalized, serving as the primary pipeline into the Actuarial Development Program.

What are the requirements for the actuarial internship?

You need at least one passed SOA exam, a quantitative major such as actuarial science, mathematics, or statistics, and a 3.0-plus GPA. Multiple exams and strong Excel, SQL, and Python skills improve your odds. MassMutual does not sponsor visas for internship positions.

What is the MassMutual internship interview process like?

Expect a recruiter phone screen followed by one or two interview rounds. Actuarial candidates face behavioral questions using the STAR method plus technical questions on probability, statistics, and SOA exam content. The process is described as moderate difficulty and more behavioral than technical compared to consulting or tech firms.

Do MassMutual interns get return offers?

Most actuarial interns who perform well receive offers to join the Actuarial Development Program upon graduation. While MassMutual does not publish an official conversion rate, community reports suggest a strong majority of actuarial interns receive ADP offers. Non-actuarial tracks also extend return offers but the pipeline is less formalized.

Does MassMutual sponsor visas for interns?

No. MassMutual's internship postings have historically stated that visa sponsorship is not available for internship positions. International students who require work visa sponsorship are effectively excluded. Full-time positions may have different sponsorship policies depending on the role and business needs.

MassMutual's actuarial seats fill early on rolling review once postings go live. Spend the runway building proof: a remote Externship turns "interested in actuarial science" into a finished quantitative project a fall 2026 application can point at.
