I did 3 rounds of interviews. First one was with the recruiter and next two were with senior managers. I was never contacted or given an offer after the 3 rounds, however I did not follow up. I was no longer interested in the job. Listing my red flags below: 1. They can't digging deeper and seemed worried when I told them that a healthy culture is important to me. Very big red flag. I get the vibe ADP is cutthroat and doesn't care at all about their people. 2. I mentioned to my 3rd interviewer, who is local to my market, a direct competitor of them in our city that I interviewed with. He didn't even know who they were and sort of insulted them. 3. For a large corporation like ADP, when I show up to the interview, I expect more than a shared office space. I walked in the office building and ADP's name was no where to be found. I had to walk into another business to ask them for directions. They knew exactly where to send me because I'm obviously not the first to ask. Talk about a lot of turnover? 4. Had to end 3rd interview early because he had to go pick up his child. Which is totally understandable! Family comes first. But here's the thing: he was a jerk about it. Also, I don't get the impression that if I worked for him he'd be as understanding as I was.
