First it was a phone call interview with a panel, ~30 min. About two weeks later, on-site interview invitation was received. It was about 6 hours in total, with several panel discussion and individual meetings, your presentations ~10 min.

Panel interview (myself talking to two other people) over the phone. The panel had me elaborate on every project that I'd mentioned in my resume, my programming experience (languages, expertise), exposure to the field of bioinformatics, specific experiences with various types of next-generation sequencing data and software packages. The panel also had me describe situations where I had worked in teams, and my experiences (good and bad) in those teams.
