Collective Health starts with an information session via webcam that takes place with a number of other candidates. After this, they give you a homework assignment, which comes in the form of an excel sheet and you have to answer all the questions on the sheet about benefits and other healthcare terminology that you should make yourself familiar with. If you did most of it right, you move on to 2 video interviews, back to back, which are standard behavioral interviews. If you get past those, they invite you on-site to interview. You meet with 5 or so people, all of which are behavioral except for one, which is a case study of sorts. It's similar, but not the same, as the homework assignment they give you. You can ask for information and they help you a little, but you should really resolve the problem yourself. After that, I was not given an offer, but the whole experience was pretty positive and it happened over the course of 2+ months while I was still in school.
