The Western University of Health Sciences College of Osteopathic Medicine of the Pacific (COMP), in Pomona, California, combines a 30-minute interview with a short Multiple Mini Interview made of two standardized-patient interactions.
The school describes its aim as ushering in osteopathic physicians who serve patients with purpose, passion, and proficiency, with a meaningful emphasis on humanistic health care.
To get ready for both parts of the day, Confetto, an AI mock interviewer for medical school and other healthcare program interviews (MMI, traditional, panel), runs MMI practice stations as well as traditional interviews with follow-up questions.
This guide covers the interview structure the school publishes, how to connect your experiences to its stated values, and how to practice.
Confetto is not affiliated with WesternU, and the practice questions below are written by us, not taken from the school.
The Western University of Health Sciences College of Osteopathic Medicine of the Pacific Interview: Format and Experience
COMP's California interview page says the college offers both online and in-person interviews, and that the choice is entirely yours with no preference by the Admissions Committee (it notes only a small number of on-campus interviews are offered).
The MMI is a required part of the process.
Online or on campus
- Online day. Online: the interview day lasts approximately 4 hours on Zoom (welcome from the Dean, an icebreaker, admissions, student affairs, pre-clinical and financial aid presentations, networking, and the interview). The MMI takes place on a different day in the same week, in a half-hour session you choose from four timeslots. After an overview you complete two 5-minute interactions with standardized patients.
- On-campus day. On campus: the day lasts approximately 6 hours and includes a welcome from the Dean, an icebreaker, financial aid and pre-clinical presentations, an OMM demonstration, a campus tour, the MMI, and the interview. Interviews take place on a Tuesday or Thursday.
The interview and the MMI
- Interview. The interview itself is 30 minutes. You are asked to draw from personal experiences to formulate your answers, and the school says questions can be challenging and thought-provoking.
- MMI. The MMI is two 5-minute interactions with standardized patients. The school says your knowledge of medicine will not be evaluated, and instructions are given for each interaction.
After the interview
The school does not publish the number of interviewers, a scoring rubric, or the scenarios.
After the interview you complete a feedback survey and receive a decision in 2 to 4 weeks (Admit, Alternate, or Deny; the school says all decisions are final). It offers one interview per application period.
Tip: in the standardized-patient interactions, listen first, respond to what the person actually says, and stay within your role. Practice saying your reasoning out loud.
Mission & Culture Fit
WesternU describes humanism as a core principle: acceptance, altruism, compassion, diversity, empathy, fairness, inclusion, integrity, kindness, and respect. COMP's program page describes students who practice on a foundation of professionalism, benevolence, and respect.
It also notes that DOs use all the standard tools of modern medicine and have additional therapeutic modalities for their patients.
Showing fit
To demonstrate fit, connect your own experiences to these values: service, longitudinal relationships, and patient-centered communication. Explain how you came to understand osteopathic medicine, what you observed, and what you still want to learn.
If your exposure was brief, say so. The on-campus day includes an OMM demonstration, so you can ask an informed question about OMM training, but do not claim skills you have not been trained in.
Local Healthcare Landscape & Policy Signals
COMP does not publish a list of policy topics or local-issue themes for its interview, and the MMI is described as not evaluating medical knowledge. You do not need to memorize statistics about California health policy.
If an interviewer asks about a healthcare issue you care about, state the issue, the competing concerns, what you would want to know, and how it affects the patient in front of you. For current numbers, use primary sources (California state agencies, the school, CDC, KFF) rather than secondhand figures.

Preparation Checklist
Use these targeted steps to practice with Confetto and turn your experiences into crisp, patient-centered answers.
- Mock interviews. Run AI mock interviews that mirror a 30-minute experience-based interview and two 5-minute patient interactions, with structured feedback on clarity and empathy.
- Listening first. Drill listening-first responses: reflect the person's concern before choosing an action, and stay within your role. Confetto's scenario variants help you avoid scripted responses.
- Your path to DO. Practice explaining your path to osteopathic medicine honestly, including what you have observed and what you still want to learn.
- Analytics. Use analytics to track pacing, completeness, and bias-aware language.
- Online setup. If you are interviewing online, test your camera, microphone, and Zoom setup, and note both your interview-day and MMI appointments.
FAQ
Does COMP use an MMI, and how is it structured?
Yes, as one part of the process. After an overview, you complete two 5-minute interactions with standardized patients; the school says your medical knowledge is not evaluated. Online applicants take the MMI in a half-hour session on a different day the same week. A separate 30-minute interview asks you to draw from personal experiences. The school does not publish the number of interviewers.
Is the COMP interview online or in person?
Both options are offered, and the school says there is no preference by the Admissions Committee. Online interviews use Zoom and last approximately 4 hours; on-campus interviews last approximately 6 hours and take place in Pomona on a Tuesday or Thursday.
How can I show alignment with COMP's mission and culture?
Connect your service, clinical exposure, and communication experiences to the school's stated values of humanism, professionalism, and respect. Be specific about what you did and what you learned.
What California policies and current issues should I be ready to discuss?
The school does not publish a topic list, and the MMI does not evaluate medical knowledge. Be ready to discuss a healthcare issue you care about and its trade-offs, using primary sources for any figures.

COMP's mission and history
COMP's mission is to prepare students to become technically competent, culturally sensitive, professional and compassionate physicians who are ready for graduate medical education, keep learning, and serve society with comprehensive, patient-centered care grounded in the osteopathic philosophy. The college says it does this through its curriculum, translational research, service, osteopathic clinical practice and osteopathic graduate medical education.
COMP was founded in 1977 in response to a shortage of primary care physicians in the western United States. In 1996 it was restructured into a university, Western University of Health Sciences. COMP shares its mission statement with WesternU's Heatherington College of Osteopathic Medicine (HCOM, formerly COMP-Northwest) in Lebanon, Oregon, and AACOM notes that HCOM uses the same application as the Pomona campus.
Facts worth knowing for a "why COMP" answer, if they connect to your own experience:
- California applicants make up most of the class: AACOM's 2024-25 profile lists 207 in-state and 18 out-of-state first-year matriculants at COMP.
- AACOM lists the same tuition for in-state and out-of-state students.
- A DO/MPH dual enrollment program with Claremont Graduate University's School of Community and Global Health.
- The curriculum is a four-year program that stresses how biological, clinical, behavioral and social sciences depend on each other, with integrated and early clinical experience.
- The WesternU Patient Care Center serves residents of the Pomona Valley and is a training site for WesternU students.
Getting to the COMP interview
COMP applies through AACOMAS and sends its supplemental application only to screened applicants. After a holistic review of the primary, competitive applicants get an invitation and a secure link. The committee says grades and the MCAT matter but also weighs a well-rounded background, work experience, letters, interest in and knowledge of osteopathic medicine, and professional promise.
- Recommended benchmarks: 3.0 science and overall GPA and a 500 MCAT.
- Supplemental opens July 15, 2026 and closes March 15, 2027. The fee is $65, waived if you had an AACOMAS fee waiver.
- AACOMAS deadline: March 1, 2027. For best consideration, COMP suggests applying at least six weeks before the deadline.
- A letter from a physician (MD or DO) is required, and only in-person shadowing counts.
- There is no Early Decision program.
Interview week logistics at COMP
The guide above covers the day itself. These are the practical points from COMP's California interview page that it doesn't repeat.
- COMP & Conversation: an informal evening social before your interview, hosted by COMP Student Ambassadors. Spouses and significant others may attend.
- Zoom links arrive three days before your interview. Times are Pacific. You can check in 10 minutes early and wait in the waiting area.
- Interviewers leave time at the end for your questions, so have a few ready.
- Your interviewers and standardized patients have your cell phone number in case your technology fails.
- You need a government-issued ID, verified at check-in.
- Once the interview is over, you can't send interviewers more information, and committee decisions are final with no appeal.
- COMP follows the AACOMAS traffic guidelines for deposits. AACOM lists a $2,000 nonrefundable acceptance deposit, applied to tuition.
