Western University COMP (DO) Medicine InterviewFormat, Questions & Prep Tips

Interview September through MarchDecisions Rolling decisions
Overview

Western University of Health Sciences College of Osteopathic Medicine of the Pacific (COMP) uses a **traditional interview format** — typically two sessions (faculty and student) at its Pomona, CA campus (or the Northwest campus in Lebanon, OR). COMP is a health sciences university with programmes in pharmacy, nursing, PA studies, and veterinary medicine alongside osteopathic medicine, making **interprofessional education (IPE)** genuinely embedded in student life.

COMP requires **CASPer** for its application screening. The school's Southern California location means clinical training occurs in one of the most diverse and medically complex regions of the US — the Inland Empire has high rates of diabetes, uninsured Latinx families, and rural agricultural health challenges.

COMP is notable for its **One Health initiative** — integrating human, animal, and environmental health perspectives — and for its research programmes in musculoskeletal medicine and OMT efficacy.

Questions

Sample Interview Questions

motivation

Why osteopathic medicine, and what about the DO approach fits the kind of physician you want to become?

Ground the answer in the osteopathic tenets, the structure-function relationship, and OMT as a clinical tool. Frame DO positively and on its own merits. At COMP you can link it to the school's musculoskeletal-medicine and OMT-efficacy research strengths.

motivation

COMP sits within a multi-college health-sciences university with pharmacy, PA, nursing, dental, and veterinary programmes. Why does training in a genuinely interprofessional environment matter to you?

Show you understand that real IPE means shared coursework and team-based care, not just shared buildings. Connect it to safer, more coordinated patient care and to your own collaborative experiences.

motivation

What draws you to practising in Southern California's Inland Empire, one of the most medically underserved regions in the state?

Be specific: high diabetes prevalence, large uninsured Latinx and immigrant populations, agricultural and warehouse-worker health, and primary-care shortages. Tie it to evidenced commitment, not just the appeal of the location.

motivation

Western U's One Health initiative integrates human, animal, and environmental health. Does that framework resonate with how you think about medicine?

One Health connects zoonotic disease, environmental exposures, and human illness. If you have veterinary, public-health, or environmental experience, use it. Show intellectual curiosity rather than reciting the brochure.

ethics

A farmworker in the Inland Empire presents with heat exhaustion after a long shift in the fields. Beyond the acute management, what systemic factors do you weigh?

Heat-illness prevention rules, pesticide exposure, lack of paid sick leave, uninsurance, immigration fears, and the FQHC and promotora infrastructure. Show structural thinking and respect for the patient's constraints.

ethics

A patient declines a recommended vaccine for their child based on information they read online. How do you respond?

Respect autonomy while fulfilling beneficence and your duty to the child. Explore concerns, use motivational interviewing, share evidence without condescension, and keep the relationship intact for future visits.

ethics

You discover a senior clinician has been cutting corners on documentation in a way that could affect patient safety. What do you do as a student?

Patient safety and professional integrity outweigh hierarchy. Describe escalating through appropriate channels, the difficulty of speaking up against seniority, and how to do so constructively.

communication

Describe a time you learned something important from a non-physician clinician. How did it change your clinical thinking?

Pick a real encounter with a pharmacist, nurse, social worker, or PA. Show humility and that you value distributed expertise. This maps directly onto COMP's IPE culture.

communication

Tell me about a time you had to deliver information someone did not want to hear. How did you handle their reaction?

Empathy, clarity, allowing silence, and checking understanding. Avoid sounding clinical or detached; show you can hold difficult emotion.

academic

COMP uses an integrated, systems-based curriculum alongside a demanding OMM lab. How do you learn, and how would you keep up?

Concrete, evidence-based study strategies and honest self-knowledge. Reference COMLEX-USA (and USMLE if you plan both) accurately and how you recover from a poor result.

academic

Is there a part of your application — a grade trend or gap — you would want the committee to understand in context?

Own it, explain the lesson, and point to a sustained upward trajectory. Do not blame others.

role-play

A patient who speaks limited English has come in without a family member to translate. The clinic is busy. How do you proceed?

Use a professional interpreter (phone or video), never a child or rushed bilingual staff member. Show patience and awareness of the legal and ethical right to language access, relevant to the Inland Empire's Latinx population.

role-play

You are a student and a diabetic patient admits they have not been taking insulin because they cannot afford it. Talk to them.

Avoid judgement; explore the real barrier, problem-solve (patient assistance programmes, formulary options, social work), and rebuild trust. Demonstrate the whole-person approach.

data

You are shown county data: diabetes-related hospitalisations are far higher in parts of the Inland Empire than in coastal LA. How do you interpret it?

Look beyond individual choices to food access, insurance, primary-care availability, and built environment. Propose both clinical and population-health responses; avoid blaming patients.

motivation

What experience first made medicine feel real to you rather than idealised, and how did it shape you?

Reflective and specific. Show you have seen the difficulty as well as the reward and that it deepened, rather than dented, your commitment.

ethics

An uninsured patient needs a workup you suspect they cannot afford. How do you balance thoroughness with cost?

High-value care, shared decision-making, sliding-scale and FQHC resources, and honesty about trade-offs. Show stewardship without compromising safety.

Prepare

How to Prepare

01

Research the One Health initiative; it is distinctive to Western U and a natural interview topic.

02

Know the Inland Empire health context: diabetes prevalence, agricultural and warehouse-worker health, uninsurance, and Latinx healthcare access.

03

Complete CASPer early and reflect beforehand on ethical reasoning and professionalism.

04

Prepare concrete interprofessional stories; vague endorsements of 'teamwork' will not land in this IPE-heavy environment.

05

Have a positively-framed 'Why DO?' answer rooted in the osteopathic tenets and OMT, and be ready to discuss COMP's musculoskeletal/OMT research interests.

06

Confirm whether you are interviewing for Pomona or the Lebanon, Oregon campus and tailor your community knowledge accordingly.

07

Map your experiences to the AAMC core competencies and rehearse a clear study/learning plan that names COMLEX accurately.

Pitfalls

Common Pitfalls

Not engaging with the genuinely interprofessional nature of training; COMP expects substance, not slogans.
Treating One Health as marketing rather than understanding the human-animal-environment links.
Giving generic underserved-care answers instead of specific Inland Empire knowledge.
Leaving CASPer to the last minute or treating it as an afterthought.
Presenting DO as a backup to MD, or being unable to discuss OMT and the osteopathic tenets with depth.
FAQ

Frequently Asked Questions

One Health integrates human, veterinary, and environmental health, recognising that these are interconnected (for example via zoonotic disease and shared environmental exposures). It reflects Western U's multi-college structure, which includes a College of Veterinary Medicine alongside the osteopathic programme.

Yes. Western U/COMP uses CASPer as part of its screening, so complete it early in the cycle. Applicants apply through AACOMAS plus the Western U secondary. Reconfirm exact requirements for your application year.

COMP has its main campus in Pomona, California and a Northwest campus in Lebanon, Oregon. Confirm which you are applying to, since clinical training sites and the surrounding community context differ.

All DO students sit COMLEX-USA, which is required for licensure. Many COMP students also sit the USMLE, especially when pursuing competitive specialties, but it is the student's choice rather than a requirement.

Genuinely. COMP students share facilities and some coursework with pharmacy, PA, nursing, dental, optometry, podiatry, and veterinary students, and participate in structured interprofessional education experiences. Be ready to discuss team-based care meaningfully.

Race is not used as a factor. Holistic review weighs socioeconomic background, first-generation status, geographic and lived experience, and fit with the school's service-oriented and interprofessional mission.
