I applied online. The process took 4 months. I interviewed at Library of Congress (Washington, DC)
Interview
This was a panel interview with four interviewers. They asked questions related to the skills required in the job description. The interviewers were kind, but they were not overly friendly. Most of the time, they took notes about my responses, which is standard for a PBI in this field.
