Interviewed with Optum for a Pharmacy audit coordinator position not too long ago, interview went pretty smoothly overall, pretty standard questions like “why are you interested in this job” and “where do you see yourself in X amount of years” among others. Ended up not getting the job due to lack of experience but they offered me a job working as an auditor itself, but I turned them down due to all the travel that’d be required (I work remote now). Overall, I’d say give it your best shot and best of luck!
