Does your resume reflect the type of care you are giving ( comparable to Med surg)? When you are asked about your experiences, how do you describe them? You are getting interviews which is great!! So find some one to help you practice for the interviews, ask hard questions and help you fine tune your responses to questions about your skills. Maybe there is something you are doing in the interview that you need to improve. If you really believe that your experience is equal then you have to SELL YOUR SELF. Best of luck!
