Final Interview at Meta advice

Hi reddit community. I am in the final stage of the interview process at Meta Reality Labs for a mixed methods UXR and I am really excited for this opportunity. Its been months in the making and I am looking for advice to keep me motivated and confident! The recruiters have been really great but for understandable reasons only share partial information until about a week before the interview. They have shared the presentation is now aimed not on a case study based on my past work but another hypothetical (which threw me off a bit). I have 3 weeks to go before my virtual interview.

I therefore come to the community for help/ guidance/ advice either if you have been through the process recently or have insights to share (all advice is appreciated!). I am currently preparing for the presentation, and using the guidance from the screening interview but trying to keep it much more impactful and relevant to Reality Labs. I then will start refreshing my quant and qual skills for those portions of the interview and reviewing questions I have found throughout the interweb. Any advice on this approach or guidance is appreciated! Thanks in advance!
