After passing object oriented online assessment, I had a 20 minute phone call with a recruiter asking basic questions about resume. I was rejected 3 days later. He was nice but not incredibly engaged.

The interview process was long and well thought out. You had the opportunity to talk to many different individuals and they all spoke v highly of the firm. Each round has a unique quirk to it. They walk you through problems if you don;t know how to do it initially.
