I applied online. The process took 2 weeks. I interviewed at BDO (New York, NY) in Apr 2010

I applied through college or university. The process took 2 weeks. I interviewed at BDO (Dallas, TX) in Jan 2015
Interview
On campus interview with a few Directors who presented in one of my classes. Got a call a few days later to come interview in the Dallas office. They flew me out and had me interview with some associates and directors there. It was super laid back. I got a call back a week later with the job offer.
I applied through a recruiter. The process took 3 months. I interviewed at BDO (Atlanta, GA) in Oct 2013
Interview
Started with a phone interview from their recruiter, who reached out to me via Linkedin. Phone interview was basic behavioral questions. After phone interview, I was reached out to a couple weeks after. Went to their office and interviewed with 2 directors and an associate. Directors gave most interview-type questions (e.g. behavioral). Associate gave more of an overview of the job to see if I would enjoy the position. Couple weeks after got the offer. Overall process took 2-3 months.
