Weird interview. No one was there to let me into the suite--eventually an employee begrudgingly got up from her cubicle and let me in to the conference room, but it was clear that this was not her job. I then met with 7 people at the same time in one room, mix of associates and partners. Clear that most had not reviewed my resume, awkward interview to say the least. Followed-up with the HR person 2 weeks later and was immediately told I was not selected.

To the point, Not difficult. The hiring manager asked practical questions and offered a good idea of work hours / corporate culture. Accepted the offer after a fairly short interview process.
