lean on etl's. the ones who prep you are your friends and treat them like it. if you're nervous talking to them you're going to flunk with someone you don't know. your direct one will usually do your first one, but i never did it cause my store wasn't organized.
every stl/dtl has their approach. my stl didn't do interviews, he just waited till i wowed him as a tm to approve me. my dtl knew i prepped but i came off non nervous/non scripted. my friend in a different state had no interviews at all. sometimes you get grilled both times.
always look for high scope answers. i always go to this example cause its the easiest to show it. a mom and kid ask you were birthday candles are. they dont' want you to know where the candles are. they want you to strike up a conversation, talk to the kid about his birthday party, build the basket. talk how you want to create that experience that brings mom back and also that kid loves getting toys/presents from target. your creating a loyal future generation.
