A full day - 30 minutes sessions with various team leaders, senior analysts, department chair, and program director. I also had lunch, which was more casual, with a couple of analysts. The day started with HR in a separate building. After I accepted the offer I had a drug test, and not one but two tuberculosis tests. As an employee you are highly encouraged to get a flu shot, but this is not required since the department is separate from patient care areas. The on-site flu-shot clinic is stunningly efficient - gone in 60 seconds and a free lollipop.
