I applied online. The process took 5 months. I interviewed at ADP (Chicago, IL) in Aug 2016
Interview
strange... first two interviews were basic screening questions. the third interview was a basic techie interview, the fourth interview was more in-depth. Never made it to a fifth interview. The whole interview process spanned almost 2 months. All interviews were within 2 days of their request. AND then it was almost 3 months before they responded back after that.
Interview questions [1]
Question 1
basic ones....how to lookup the IP of a machine, or how to view an arp table, my favorite one was when the question on how I would research an issue
