Very easy and down to earth. They treat you with respect and work with you during the process. I had 2 total interviews and they were both online. ADP is looking for young and inspiring people to join their culture.
I applied online. The process took 2 weeks. I interviewed at ADP in May 2013
Interview
I heard about ADP through a friend and submitted my resume on their career website. I got a response via email a few days later requesting a phone interview. The recruiter called me promptly at the time we agreed on. After the phone interview I was scheduled for a face to face interview with the hiring manager for the following week. The manager was very professional and nice. The interview lasted about an hour and was overall quite enjoyable.
Three rounds, your regional recruiter will reach out to you for a screening call, then there's an interview with the VP or your future SE, then there's a final confirmation call.
