Well first off, thanks for your help everybody.
As far as dress goes, I ended up wearing some khaki capris that I found in a box under my bed, that my sister gave me last year and I had forgotten about
with a light blue and white top. The interviewer was wearing black capris, a black and white top and flip flops. There was one girl there in a strapless sundress.
But the interview itself, I was kind of meh about. The business is run by a woman and her daughter, and I just found them both to be kind of unprofessional. First off, the "interviews" were just having everyone who inquired meet at a Starbucks where we filled out applications and then they talked to us each for maybe two minutes.
I got there 10 minutes before the start time and they weren't there yet. There were a lot of applicants there already. They came in at 3, but, as this is quite a tiny Starbucks, there wasn't a table big enough for all of us, so we had to split into two groups. I don't know, but I think if it were me, I would have been there half an hour or so beforehand to get set up. Some of her application forms weren't printed on both sides because she said she wasn't very good with computers. Also, she brought her dog.
The job itself sounds like it would be easy to be taken advantage of. The pay is 3 dollars an hour less than I was making at my last job. It's a Molly Maid kind of thing where they do commercial properties early in the morning and then do homes later in the day. She told us that we don't get breaks because we get our breaks in the car on the way to the next job. Oh, and we don't get paid for travel time.
So in effect, no paid breaks, which I believe is illegal here, but...
So I haven't heard back yet, but my references have not been contacted yet, either. So I will wait and see.
