I did a "phone interview" in which the woman mumbled the whole time. It was simple questions like if I could work in the U.S. and specifics about the job. They also asked me at least (at least!) three times if I've ever stolen anything. I'm not sure why they wouldn't just do a background check if they were that concerned. They told me everything sounded good, and that I just needed to come into the office.
An appointment at my closest office was cancelled because people keep calling off (this is exactly what I was told over the phone), and I was told that I would have to go to an office that was an hour and a half away from me. The appointment was made for a week out, and the woman on the phone huffed and puffed when I asked for a specific time instead of just a date. She was hacking loudly in my ear the entire time, not even attempting to keep the phone away from her mouth, and not even apologizing. She also kept putting me on hold, like scheduling appointments is some kind of complicated process. I got scheduled and was told to complete "pre-employment documents". This was a disaster. I was an IT helpdesk agent in the early 2000s and I continue my computer education, but I was completely unable to figure out how to get to their online documents without spending at least half an hour doing ridiculous work-arounds. They offered no assistance other than to make sure I had Adobe downloaded (which I do, and it works fine). I decided the frustration wasn't worth it. I called back the next day to cancel, and was badgered about why I would cancel my appointment. I reiterated to please cancel my appointment and then I hung up. I then got a very unprofessional and demeaning email questioning why I cancelled. From the way I was treated, I'm betting they get commission for placing people. I assume any business who uses this company to hire, does so because they are probably the cheapest.
I have an acquaintance who has been working for Adecco for about two years, and she has a tendency to be unnecessarily rude to everyone she meets. It seems to me that this is how everyone at Adecco acts.
