Don't worry about the online postings. If you have an interview, just go for it and rock it. Often MAcys has more positions available than the website will state.
Ex: Not too long ago I was looking to start working in cosmetics again, so I interviewed with Shiseido for a counter manager position at a specific location. After I passed that, they told me to apply to MACYs so I could set up an interview with them. But the position wasn't even on the website, so they told me to just apply for any beauty position for that location. Then set up an interview with them for the position (although i ended up declining to go back to MAC instead)
Good luck to you!
