Their sign states that if you are more than 15 minutes late, you will not be seen, but they don't' mind leaving you sit there waiting to be seen an hour after your appointment time.
Stay away from this company. Prior to even speaking with you, they will strong arm you into providing your social security number. If you choose not to provide unless an offer of employment is extended, they will not even meet with you. Be very careful about who you provide this information to, as each office is owned independently and your information is only as secure as the employees trustworthiness that they will hire for the next 7 years.
They will encourage during your interview that there are numerous options for placement, but in my experience, once I walked out the door, I never heard from them again, despite emailing my recruiter and leaving messages for her. When I finally called for the last time, I requested my application be shredded and my social security number be removed from their records, they refused and the call ended with me being hung up on.
There are a lot of staffing agencies out there that conduct themselves with professionalism. This is not one of them.
