How to nail my interview with zero experience? Any tips?

Hello! I have recently been invited for a DA role interview and seeking out tips on how to nail this first interview. Abit of background, I didn't initially apply for this role but another one that is less technical in my industry. It turned out that I had impressed the talent lead during the phone screen and was put forward for this technical role with some of the transferrabke skills I had spoken about . I have always wanted to pivot into a more technical/data focused role while also applying domian knowledge i already have in my field. With this interview I feel like I'm being given a chance to make this pivot a reality. At the same time I have major imposter syndrome, super nervous and have started preparing the hell out of it.

I don't have any experience in a working environment using python, sql and power BI (never really had a chance to learn in the roles that I was in due to business needs, but I have started to learn in my own time for the last few months). The learning is super interesting but can get very overwhelming.

If anyone has any tips on how to approach the interview as someone with limited/basic knowledge in the space of DA and how I can articulate my thought process, I would be very greatful!!
