Received an employee referral into ADP, had an initial phone interview from their corporate recruiter who is based in California. After the interview, he was to schedule an interview with the local hiring Sales Executive. I literally had to call him every week to get it scheduled and he would either make an excuse about not being able to answer the phone, or there were scheduling conflicts with the local team. After weeks of scheduling and rescheduling, I finally was able to sit down with the local Manager(s). There are two Sales Executives (managers) that I interviewed with, both one on one interviews, one right after the other. Overall, was very unorganized process, and it took over 3 months to finally get an offer letter.
Also, while still employed, I referred a friend to ADP and the process was very similar, she did not opt to choose to pursue employment with ADP.. Leads me to believe my experience is a common occurrence.
