Johns Hopkins Medecine is notorious for a slow, cumbersome, multitiered, and disjointed interview process in which various departments such as OccHealth, HR, and management do not always receive the necessary documentation to allow for a smooth and efficient hiring process. They also tend to place applicants through marathon interview session with multiple employees without comprehensively explaining each individual's role and how he/she may or MAY NOT interact with the new hire on any given day. I know that I interviewed with a number of people for whom I never directly worked with or for.
All that being said, while unwieldy, slow, and sometimes confusing, everyone that I interviewed with was kind, candid, insightful, and clearly interested (eventually invested) in my success.
