I'm moving to a new job as a business analyst, but I have a background in PM & Data Analytics.

I few days ago, I posted that I was outsourced by an automobile company. Since I realised what happened, I started to look at companies that are actually about data analytics. After several CVs were sent, I got my first HR interview after my last job. I'm so excited for the possibilities of this new role, as a Business Analyst Jr. Do you have any advice for the new interview?
My background is mostly in volunteering related to management and mentoring, and I'm an engineer, so I don't really have the background in finance. I have done a few projects with data, and I said before I've led some STEM initiatives for volunteering.
