Transparency and honest with perspectives residence wanting to attend a two-year postdoctoral fellowship is critical. The time commitment and academic and clinical rigors need to be discussed openly and honestly. Moreover, no guarantees of post-attendance employment should ever be implied. This is not to say you should not talk about employment opportunities...you should. I think the education of why your program is "decidedly and distinctly different" is appropriate and market responsive.
The interview should be a discovery session between you and the prospective candidate to your institution.
