Very relaxed and informal. They are looking mainly to make sure you are not extremely awkward. This position is very unique at UnitedHealth, and it is intended for college students. Consisted of basic behavior questions. 3 Interviews in one day each lasting about 30 minutes. In two of mine I ended up talking about stocks nearly the entire time. Have basic knowledge of UnitedHealth Groups business segments and a solid understanding of Obamacare.
