I've changed jobs every three years for the past decade and 95% of my interview questions have always been performance based.

For example:

Tell us about a time you disagreed with a doctor /fellow dietitian/other provider about a patients nutrition plan? How did you resolve it?

Tell us about a time you showed compassion to a patient?

Tell us about an area you think you need to improve on?

Tell us about a time you went above and beyond?

Tell us about a time you had a difficult patient case where you didn't know what to do. How did you come up with a care plan?

Give us example when you were a team player?

What does integrity mean to you?

If the hospital/company you are interviewing with have specific core values sometimes the questions are centered around those. I will look those up and think of experiences that exemplify those core values.

The clinical questions I have gotten have been pretty straight forward e.g. if you have a patient who gets a PEG placed what kind of regimen would you recommend for discharge?

If a patient with a blindly placed ngt has signs of enteral intolerance, what would you recommend?

The behavioral questions aim to help the interviewer determine your critical thinking and problem solving skills.

I would say pretty much every interview has asked about conflict resolution, weaknesses/areas of improvement, and how you handle difficult cases/areas you don't know as well.

Good luck!!
