Trinity Life Sciences Case Interview Practice: Free Case and Prep Resources

Work Trinity's own practice case first: two hypothetical drugs, patient sizing for each, a peak revenue calculation and a recommendation, in six questions. Do it out loud and timed before you open the answers Trinity shows behind each question. Then train what its cases lean on: market sizing built from disease and treatment facts, quick case math and reading exhibits, and a few behavioral stories, since Trinity says its interviews include both case and behavioral parts. On Road to Offer a free account includes 1 full AI-graded case, and our life sciences guide, sizing drills and worked cases need no account. Firm-style cases are practice cases written for Road to Offer or adapted from university consulting club casebooks, not the firm's own cases.

Start on Trinity's own site: its practice case study is free, needs no account and has an answer behind each of its six questions. On Road to Offer, the sample case on this page is a pharma-style case you can run in your browser with no account, and your first full case with the AI interviewer is free with a free account, no card. Dunmore Cargo Bikes (market sizing) and HarborHealth (a healthcare acquisition) are worked cases to read free, with a model answer for every question.

It is the one case Trinity publishes for candidates, linked from its careers and early talent pages. A mid-size pharma company with a pediatric focus considers entering dermatology or ophthalmology and is looking at two hypothetical assets, a topical drug for underarm hyperhidrosis and a biosimilar injection for wet AMD. Six questions follow: size the eligible patients for each, name the factors that decide the choice, calculate peak revenue from a table, then argue the case for each product. Use it as a timed rehearsal: answer each question out loud, write down your number, then open Trinity's answer. Our sample case on this page follows the same order with a different disease.

Trinity says most interviews are 45 minutes, held over Microsoft Teams or on campus, and combine behavioral and case components. Its published case suggests the case part: pharma patient sizing, a revenue calculation and a prioritization question. Candidates report life-science-specific cases with a lot of mental math, and some report three separate case interviews in one process. Trinity's pages do not say who leads the case, so practise both opening with your own structure and answering one question at a time.

Trinity does not give a number. Its application FAQ says selected applicants go through a series of behavioral and critical thinking or case interviews with consulting staff, usually over a few weeks, with a virtual interview and then a Superday at its offices. For the externship, its 2026 page describes a self-recorded video interview and one 45-minute Teams interview. Candidates report anything from one week to two months, most often two to four weeks, and the process differs by office and level.

Trinity looks for interest rather than a specific degree for entry roles: it says it hires undergraduate and advanced degree students, and lists science and business courses and an interest in the intersection of life sciences and business among what it looks for. Its Consultant role is for candidates with an advanced degree such as a PhD, PharmD, MD, MBA with experience or a postdoc. Either way, learn the vocabulary a pharma case uses: prevalence, diagnosed and treated patients, lines of therapy, peak share and net price.

Transition to Trinity is a three-day externship for candidates pursuing an MD, PhD or PharmD, or in a postdoc, built around a real-life project simulation of a life sciences strategy consultant's work. Trinity's 2026 page says it is first an experiential program but that Trinity may evaluate participants for full-time roles. Its interview is a self-recorded video, then one 45-minute Teams interview with case and behavioral parts. Applications were due in March for 2026, it is offered only in the US and it requires US work authorization without employer visa support, so check the current page.

Trinity's early talent page describes a nine-week internship that runs from late June to mid-August, generally for students six months to a year from graduating. Applications are due in late fall to early winter depending on the business unit, and its FAQ gives the first week of January for European internship resumes. Locations named are Waltham, New York, San Francisco, East Norriton and London, and you apply through its Careers site.

Trinity's pages do not name one. The only pre-interview step they describe is the self-recorded video interview for the Transition to Trinity externship. If you get an invitation for a test or video, follow it; the closest practice is our case math and chart drills.

Trinity does not say. Its published case is a numbered list of six questions, which reads as interviewer-led: each question is asked after the previous one is done. Practise both: open with a short structure when the question is open, and answer a directed question with a number and one sentence on what it means.

Trinity's careers page names four traits: exceptional passion for transforming healthcare, strong people skills, an innovative, results-driven and entrepreneurial spirit, and high character, including integrity. Its early talent page adds challenging yourself academically with science and business courses, leadership and teamwork outside class, and being coachable and intellectually curious. Prepare behavioral stories that show one of those, with a number in each.

Two Trinity associate consultants give advice on its early talent page: prepare with a friend or classmate because the hard part is saying your insights out loud and being comfortable with imperfections, and do many live mock cases and behavioral interviews because reading and solo practice only go so far. Do not neglect the behavioral stories either: one of them says to have a few ready that show teamwork and handling challenges.
