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.

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: 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: 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 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.
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.

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.

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.

Western University COMP interview questions to practice

These questions are written by us for practice. They are not COMP interview questions.

“Why osteopathic medicine? What did your exploration of it change about your expectations of medical training?”
“Describe a time you learned someone's concern was different from your first assumption.”
“Tell me about a time you advocated for a person's cultural or spiritual needs.”
“What did you do when someone asked for assistance beyond your authority?”
“How do you respond when feedback identifies a weakness you had not noticed?”
Standardized-patient practice: a person arrives frustrated because instructions changed and they worry about losing wages by staying longer. You have five minutes. What do you do?
Standardized-patient practice: a person is embarrassed that they do not understand a form. How do you respond?
“Why do you want to train in California?”

Preparation Checklist

Use these targeted steps to practice with Confetto and turn your experiences into crisp, patient-centered answers.

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.
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.
Practice explaining your path to osteopathic medicine honestly, including what you have observed and what you still want to learn.
Use analytics to track pacing, completeness, and bias-aware language.
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.
