Before you interview, you should learn the demographics of this group or hospital. You should be comfortable with the demographic distribution because that will determine the type of practice you will have. Regardless of whether they take care of such patients, you should always state you have no personal problems seeing anyone who needs you--you just can't go wrong saying this! Many groups and hospitals are required, for example, to have a 'life-and-limb' list of doctors who rotate turns seeing uninsured emergency patients. This might also give you an opportunity to plug your special interest again.
