I applied online. The process took 2 days. I interviewed at The Broad Institute (Cambridge, MA) in Dec 2013
Interview
The interview was a full day with ~10 interviewers. Each interview lasted 30 minutes. There was also an one hour presentation of my past work peppered with questions throughout. I interviewed with the PI, other postdocs, students, project managers, staff scientists, and technicians. Questions ranged greatly between different team members.
