I applied through the website and was given a phone interview. Next I went in for an office interview with the VP of Sales. Lastly was the field ride and a panel style interview in front of 5 people who worked there.

Interview was VERY fast (Denver) - had 1 phone interview and 3 in person interviews within 10 days. Very intense so research ADP before going in for your interviews. They are look for more personality than technical sales experience. If you get through the interviews, expect one in person interview with the Sales VP, a drive along with someone in your potential role and then a role play session with a sales manager. RESEARCH ADP BEFORE GOING IN! And don't be socially awkward ;)

I applied online and heard back pretty immediately from the recruiter. We set up a phone screen and I loved everything she had to say and we had a great conversation. We then set up a personal interview for the very next day. The personal interview felt more like a question drilling process rather than an interview. Be prepared for hard questions over and over and not getting to know you as a person. Didn't feel right.
