Getting a new snake

Hey so I’m getting an new snake and I’ve had snakes before as a kid and I work with snakes but still feel like this is a new experience from me and would love some judgment free tips! So I work in a pet store and an older gentleman was explaining how he didn’t want his snake anymore he got it for his grand daughter and she turned out to not want it and offered it to me I’m gonna pick it up tm and from my understanding it’s never been handled and just gets feed two mice any advice or experience with this out there is there any questions you would ask I have an idea of what I wanna ask but id just love other ideas and other people’s knowledge to help
