First technical interview was creating a React type-ahead component from scratch given a mocked fetch endpoint. Basic styling required to match a rough wireframe. Second techical interview, I was given a rough wireframe of a bank check and asked create a "check preview" component, with pure JS (no React) which allowed the user to enter a numeric amount in a textbox. I was then asked to write a function that took the numeric value and returned the spelled out words of the amount on the screen. Third round was general UI architecture.
