You can apply online or at an in-store kiosk (I recommend the kiosk). If applying at the kiosk they usually have a red phone next to it, a screen might be displayed to pick up the phone and talk to an HR executive. At that point they will come out and set up an interview time. There is only one interview and it is mainly situational. They will ask questions such as "Tell me about a time when..." it's not difficult it just takes about an hour.
