Applied the night before, got a call the day after to schedule an interview, with a small, psuedo-phone interview beforehand (small screening questions). Scheduled for the following day, and was told to wait in the break room for the supervisor who was going to interview me, which was a little awkward. After a few minutes, I was called back for a one-on-one interview. Many of the questions used were standard fare. He then asked me if I had any questions, and seemed pleasantly surprised when I actually did. I asked "what will the training be like?", "what is the criteria for qualifying to be a full-time employee? (everyone starts off part-time)", "will I be needing any external certifications to use the equipment on this job?" etc.
After I had run out of questions, the interviewer gave me a "contingent job offer," the contingency being a background check. I filled out a form, handed it in to the proper personnel... and then waited. This process apparently tends to take a while for most everyone. Get ready to wait for a solid week, if not more, especially if you interviewed right before a weekend like I did.
After a week and several potential other interviews had passed, I started to grow a little nervous. I called into the store to see the status of the background check. Interestingly, it had just come through and I was "the first on the list to call" that day. From there, they schedule your first day, which involves reviewing company policy, setting up your payment method, and briefing you on the clock system.
Tips to potential interviewees: 1) ask questions, 2) try to remember names, 3) it's okay to call to ask for more information, 4) be sure all your information is correct, as this may cause background checks to take longer, 5) strong eye-contact, 6) review the questions but don't rehearse too much, and 7) RELAX.
