Respiratory Therapist Interview Questions & Answers
10 questions employers ask respiratory therapists, and what a strong answer looks like.
Expect questions about technical knowledge (such as mechanical ventilation management), safety and how you work with people. Use the STAR method (Situation, Task, Action, Result) and practice out loud. Below are 10 common questions with guidance on strong answers.
Respiratory Therapist-specific questions
1. Describe a time you handled a respiratory emergency.
Use a structured story with your actions and the outcome.
2. How would you respond to a high-pressure ventilator alarm?
Mention checking the patient first, then secretions, kinks and tube position.
3. How do you interpret an ABG?
Walk through pH, PaCO2 and HCO3 step by step.
4. How do you teach a patient to use an inhaler?
Describe demonstrating, teach-back and checking technique.
5. Which credentials do you hold?
List CRT/RRT and life-support certifications.
General and behavioral questions
6. Why do you want to be a respiratory therapist?
Connect a real motivation to the work itself. Mention what drew you to respiratory therapists’ day-to-day tasks (for example, assess patients’ breathing, oxygen levels and lung sounds) and show you understand the challenges as well as the rewards.
7. Tell me about yourself.
Give a 60–90 second summary: your background, the training or experience that prepared you for this role, and why this employer. Keep it relevant to respiratory therapist work.
8. Describe a time you made a mistake. What did you do?
Pick a real, low-stakes example. Explain how you owned it, fixed it and changed your process. Employers want honesty and learning, not perfection.
9. How do you handle stress or a heavy workload?
Describe a specific system: prioritizing safety-critical work first, communicating early when you are behind, and staying organized. A short example from school or work makes it credible.
10. What questions do you have for us?
Always ask two or three: what training looks like for new hires, how success is measured in the first 90 days, and what the team likes most about working there.
Speak the language
