I applied through an employee referral. The process took 1+ week. I interviewed at ADP (Roseland, NJ) in Apr 2015
Interview
After screen first with a senior HR executive, I then spoke to the division recruiter. Each phone screen was 10 - 15 minutes, and was focused on any questions I had about process and preparation. Read the description thoroughly and ask sharp questions about the expectations, metrics for success and you'll seem very incisive. It did take two weeks to get feedback which I got via a long VM from one of the division recruiters.
Interview questions [1]
Question 1
What are the first steps you'll take to take to get to understand the group once you're hired? How will you address the responsibilities of the job once you come in?
