From what I understand, the Remodel TL is not really a permanent store position because Target stores aren't remodeled every week; instead, you'd be leading potential store remodel projects. As target is still in the process of remodeling a lot of their stores, along with presentation, PML, VM, and some GM TMs, the Remodel ETL and Remodel TL positions were created to basically run the remodel show and partner with all of the contractors, vendors, HR, district, and any other party associated with the remodel; it's a really unique position actually. You don't really have a home base so-to-speak; you'll be shifted around. You probably can't find a lot of info about it because the position is rarely posted as they're mainly back-filled by existing ETLs and TLs looking to move up. The good thing about being in a remodel position is that it fast-tracks you, so if you lead well, you can potentially move up the target ladder faster than someone that may have been in that style TL position; this isn't always the case though.
With interview questions, just prepare for the infamous STAR method, which I'm sure you've heard of as it's unique to all business positions. There are also numerous questions on Reddit and some threads on here regarding interview questions. I also vaguely remember stumbling across some youtube videos for target leadership specifically. Just do some digging! Most TL questions are consistent across the department, so I'd just look into that; it's a lot about how you show ownership and leadership characteristics in situations and roles held in the past.
I'm not in a leadership position, and I'm not really with the company anymore. Take what I'm tying to you with a grain of salt; I'm just someone that knows where to look to find a lot of information, lol.
