I found out about Ajilon through a job listing they posted on the internet. They weren't upfront that they were an employment agency. I didn't really care so I went in for an interview anyway and signed up as an potential associate applying for the specific job that I saw listed. They made me fill out some forms on the computer and I waited about over an hour after my scheduled time to see a representative. During the interview, the rep made it sound so promising that I'll hear back from them the next day or two, but they never called me back. When I called back to follow-up a week later, I was forwarded to a voicemail. The next day I received a call saying that they haven't heard from their contact but they'll keep me updated. It's been almost three weeks now and I still haven't heard from them. I wouldn't rely on them to find you a job.
The office itself is located in a new office building. This Ajilon branch is very new and everything seemed new. There is no free parking, though. You have to pay $4 for parking. If you want to use their service, I'd just go to the website, instead of actually going in, to save $4. The face-to-face interview for me was short anyway; nothing you can't do over the internet (i.e. submit your resume, etc.).
