I applied online and within 2 or 3 days, had a phone interview. After speaking with the manager over the phone, I was asked to come in for a formal interview. I showed up a little early and had to wait for a different manager to become available. Finally, I was shown back to the employee area (faced with numerous interruptions) where I was asked "What do you know about Michaels, Why do you want to work here, Do you like arts&crafts?" I was hired on the spot! When I went in for orientation, it was painful. I took an overly detailed and exhausting tour of the store ("this is the yarn aisle. So if anyone asks about yarn, knitting, crocheting, uh... that kind of stuff, go here. If someone knits an afghan or a hat or a blanket or slippers, they come here. If they crochet afghans, hats, blankets or slippers or anything, show them this aisle. If they need yarn, this is it ETC ETC") Then I sat in front of the computer doing video training and safety training. The manager came in as I was working on that and kept saying to skip this or that because it wasn't important. I had to rush through the manual and training so that the other hire could begin the process. After that, I was told to watch the cashiers work and see how it's done. After about 10 minutes of standing there creepily, the cashier tells me to stand behind the register and see what she does. She then proceeded to tell me how much she hates her job, how bored she is, I watched her check FB and text and she kept saying "I'm not gonna show you this, you'll learn later." After watching her for 5 minutes, the manager asks if I'm ready to begin and puts me on a register for about 15 minutes. After that, I was told to go home and look over my packet of info. (The packet tells you more or less how to do your job, but not company policies or anything super helpful.)
If you have prior cashiering experience, don't want a lot of hours or a high paycheck, go for it. Otherwise, stay away. You will be on your own with very little knowledge of how to do your job.
