A few phone interviews with a recruiter, a director, and a manager. Then, if they like you, they invite you to read a book, make power point presentation, read a short research paper, be able to present analysis of it, and then a short writing assignment.
After that, they asked me to have a few more phone interviews with various people, called my references, and made me an offer.
This was by far one of my favorite interview processes ever. I loved making the presentation and actually being able to deliver analysis of relevant material. It took me more hours than I would normally dedicate to an interview, but it was worth it and I had fun with it.
Least favorite was them rushing me in the end. The recruiter who was supposed to call my references was pushy and wanted to speak to them all in one day. It was understandable due to internal deadlines, yet made me uneasy and uncomfortable. In particular in regards to my references. When I ask someone to speak on my behalf, I do not expect them to drop everything and do it on my timeline. They are busy people and I have to be respectful of their schedule.
Benefits package was good. Salary needed to be at least 10-15% higher to be really competitive.
