The interview process was very long, it started in August and got a ding letter in November. There was two phone screenings, after which I was invited to interview at the office. The recruiter informed me that there would be two to three interviews in the morning, each an hour long, and then a break for lunch, which they would provide. At the end of lunch, they told me they liked me and therefore would proceed with the afternoon interviews for another three hours - however, I could have been eliminated at that time afterwards. Following the in-office interview "super day," I had another two interviews over the phone. The HR rep I was coordinating with was either very unorganized, or very overworked because there was a long time in between responses to emails, moving towards next steps, and clear communication in answering questions. I liked the firm and everyone I met was bright, and enthusiastic, but the needs of the team changed and no longer were they looking to fill the position.
