Any casual attire that makes u feel comfortable.
Noramally, you should wear business attire.
Let me tell you about my experience with this company. I applied for a CSR position and received a phone call from them yesterday. I was on the road when the call came in so couldn't stay on the phone long. The gentleman I spoke to asked me to come in the next day at 9 am for an interview and asked me if I knew where they were located. I said I didn't and asked if he could please email it to me (he had my email thru indeed, he repeated it to me and was correct) Well, I got home later that day and went to my email and there wasn't an email from him. I continued to check my email throughout the rest of the day and the next morning and still no email. I googled their address and Boca came up and N Lauderdale came up, so I went to the location in N Lauderdale and got there 5 minutes before the interview was scheduled. I wasn't sure which building to go in to and went into the wrong building initially. I showed up wearing a dressy blouse with dressy shoes and a nice pair of jeans and I was told to leave. SO DON'T WEAR JEANS. I should have known better, but I looked nice and wish they could have made an exception since I never even received an email from them to guide me, appropriate attire, location, etc...
