Three step process. First an easy phone interview, gives you the ins and outs of the company and full details of compensation. Second was a face to face interview which took a total of 20 minutes, nothing out of the ordinary. Third was an 8 hour long interview, complete with an hour and a half of interviews with different groups of people, then a 5 hour ride along with an existing sales representative, and ending with a role play. I didn't hear back from ADP after my final interview for a full two weeks, and when I called to follow up the HR rep told me that I should have gotten a call days ago.
