I applied through a recruiter. The process took 2 days. I interviewed at ADP in Jan 2015
Interview
Not terribly difficult. 4 step process where you interview with the VP, a hiring manager, you have a ride day in the field, and then a role play at the end with the VP and hiring manager.
Really smooth process and everyone was really helpful on laying out a timeline for it. Not too difficult at all and pretty average questions. The people I dealt with were great overall.
Initial call with the recruiter, then intro call with Vice President, then pannel interview with hiring managers, after that the last step is a role play with hiring managers/Vice President
Went smoothly the recruiter was very helpful in laying out the interview process. three rounds of interviews first screening with recruiter then zoom with hiring manager then onto shadowing/role play for final interview
