I was referred through a current employee. I didn't have an initial phone screen. I had one phone interview with a current Senior Associate. They seemed to be looking for if you were able to talk and if you had experience and were comfortable reaching out to people you don't know. Immediately after that, I was emailed with a case to review with 3 days that I received on a Friday morning. After completing the fairly straightforward case, I had a phone review with a research manager. The research manager is looking for you to have looked outside the box and told me what he has impressed where I, and others, have thought to include. After that I was invited for an on-site interview, but I declined because of another offer.
