The position I interviewed for was a part-time Renal R.D. and the most difficult part of the interview was getting the interview itself. I submitted my resumee according to the process listed on the website but it took a long time to secure the interview. My recommendation if you are in the same spot is to be assertive and call the recruiter repeatedly, or perhaps contact the unit FA directly to express your interest. The interview was not long--less than an hour--and took place with the FA of the unit and another USRC unit FA.
