I work at TDS...have been there since 2003 (when we were still owned by The Walt Disney Company). We were sold to The Children's Place in November 2004. Definite changes, mostly behind the scenes (so most guests don't even realize we're owned by TCP). Some product changes they've made have been good...some, well, not so good. I am glad they are bringing back more adult product. But the company really isn't the same since it's been owned by TCP.
That said, it still is a fun place to work. The part I hate the most, though? On call shifts. You'll get those, trust me. On call shifts are when you are "scheduled" in the sense that you have to call about 1-2 hours before the start of the shift to find out if you're needed. I hate that...makes it difficult for planning anything. Our DVD changes on Monday, I believe...so what you've been hearing will no longer be there (unless with the new DVD they kept part of it in, like the Peter Pan preorder stuff). This last DVD was about 40 minutes (yup, I tend to time it when I first hear it, because then I know how time is going once a new loop begin). We had one before the holidays that was over an hour...much better in terms of how often you were hearing the same thing. You tend to memorize the DVD pretty quickly. But the change more often then they used to...our last DVD change was in January and now we're changing it again. So it's not so bad anymore. You'll also learn new terminology...
Cast Member = employee (of course you already know this

)
Guests = customer
Box Office = Cash wrap/register area
On Stage = the sales floor
Back Stage = The stock room
...and more that I'm not thinking of right now.
OT, I'm looking at my Employment Application and there is a giant watermark in the middle of the paper consisting of three circles, positioned in a way to resemble a certain mouse, surrounded by another circle.
Yup, that's the TDS logo...it's also on our costumes (uniform shirt) and the merchandise as well.
Just a few tidbits if you do get the job....
1. TDS is not affiliated with Disneyshopping.com (and therefore all items they carry are exclusive to them). The website is still owned by TWDC, whereas TDS is obviously not. Questions regarding the website get asked all the time, so I thought I'd bring that up. We also no longer accept their returns for this very reason. We do, however, accept WDW & DL returns, provided they have a receipt dated within the last 60 days (the company is strict about this policy).
2. Catalogs are no longer in print, the last run was last Spring. This also tends to get asked a lot. TDS does sent out "magalogs" (basically a small booklet highlighting a few new products we have) but it's not what the catalog actually used to be. Even when it was still in print, we stopped carrying it once we were no longer affiliated with the website.
3. If you don't already, you'll want to get to know the parks pretty well as people will ask the most random questions about them. I see you're in California, which means your TDS will sell DL tickets (I'm in Kentucky...our side of the country sells WDW tix).
Good luck to you! I really do enjoy it here!
