how do i prepare for bioinformatics interview

[trippp]

hello all. i am preparing for recruiting interviews at two well-known east coast schools. the programs are bioinformatics phd programs. for some background information, i have a bs in math+comp sci and a ms in comp sci. my research is purely computer science-based and not bio, though i did take a number of biology classes in grad school. since leaving school, i've been working on next gen sequencing hardware/software. with respect to research, i'm interested in medical/translational genomics and statistics in relation to gene expression/biomarker discovery.

any advice for preparing for my interviews?
