Some questions, from what I can remember-
Tell me about yourself.
Tell me about a time you helped your team achieve its goals.
Tell me about a time you gave great guest service.
Tell me about a time when you gave feedback to a peer or supervisor.
Tell me about a process that you've helped to improve.
There was basically one question pertaining to each of the 11 leadership qualities Target espouses. From what I understand, they're doing away with those now though, so these may no longer be accurate.
My best advice, think of some situations in work or school where you felt you really shined or showed leadership potential. Write them down to better organize your thoughts and sort through the details. Have a handful of really stellar examples ready that you can adapt to suit different questions (i.e. a situation where you displayed both adaptability and the ability to manage a team). Also have some 'pretty good' situations to speak to as well as a situation where you messed up. For this one, be prepared to demonstrate accountability and really speak to what you learned and how it will affect what you will do as a TL.
Prepare your own questions for your interviewers. Ask them what qualities they think are most important in a leader, where they see Target's future, how they got the position they did, what they've improved, etc. Be interested in what they have to say and converse with them about it.
In addition, and others may disagree with this advice, but presentation is everything. I went into my interviews feeling not ready and totally inadequate but I did my very best to hide that. Get a nice, new, ultra-professional red shirt, wear your best shoes and khakis, and hold yourself high. Shoulders back, firm handshake, maintain eye contact. If they ask a question that trips you up, say, "That's a good question. Let me think about that." Fully process their questions and know what you will say before you speak. Stuttering and saying, "ummm," will do you no favors. Appearing confident and charismatic will do you wonders.
