Software engineer final technical interview at Odoo

I have an upcoming final technical interview with Odoo. 3 hours with a developer.

I know they do Advent of Code and LeetCode/CodeWars easy/medium and i’m relatively experienced on those.

People also talk about a final UML/SQL business case. How should I prepare this?

Do they also ask general coding questions?

If someone has recently gone through the process I wanted some help and guidance.

Thank you
