Quick but not too difficult. Had to prepare a case that I disagreed with and explain why it was not something I agreed with. Very nice people interviewing me. I was asked very thought provoking questions.

Was contacted for a phone interview then invited to the office for an interview with 3 partners. Spent 2 hours in interview. Was told that I would be contacted in two weeks regarding the position. Was never contacted and reached out to the HR Coordinator after 3-4 weeks. She told me they were still in the interview process. That was months ago. Will never understand why it's so hard for some places to send a simple email saying they went with another applicant. It's common courtesy.
