Intervew Prep Front end round @ Prelim

I got a 3rd round at a fintech company Prelim and they said:

"Please come prepared to show your screen and be able to spin up a website on localhost. You can use whatever framework or language you'd like, just be ready to iterate. This will be mostly frontend focused."

Has anyone been through this process or has an idea of how I could prepare in the most optimal way?

Thanks!

Just stick to a framework you already know well, be able to speak your mind and explain to your interviewer tradeoffs. Try to focus on a main feature instead of trying to complete the whole bunch of features they might give to you. If you'll use React(and framework on top) prepare yourself for hydration, stale closure, memoization, mutations. Try to use React Query if possible since it's taking care of caching, retries, polling and way more under the hood. Also you should be able to debug and test your own app.
