Frontend developer II

Design an autocomplete component using any framework or vanilla JavaScript, focusing on modular and clean code. It should be able to take an API and fetch suggestions as the user types.

Post-completion questions:

1. What are the areas for optimization?
2. How do you handle a situation where two API requests are made, and the stale one comes in later, replacing the response of the latest one?
3. For optimization, we debounced API calls once the user stops typing for 300 ms. Can debounce work only with time, or can we add other conditions, e.g., debounce API calls after every three characters are typed?

Design a Modular, plug-and-play, Progress Bar component using React and it should be configurable as much as possible.

• Discussions on how to Scale the Frontend Codebase in such a way that if one module goes down another one is still up.
• Discussions on Micro frontend architecture it's PROs and CONs.
• Discussions on the importance of Testing (Unit, Integration, Feature) by developers and how to do Peer Reviews ?

I was asked to explain the architecture of a Backend for Frontend (BFF) application used at my current workplace using a whiteboard. It uses a JSON schema, which is served by a Node/Express server for each user role, generating the UI based on the JSON schema.

I was asked about its pros and cons. 

I was also asked how to scale it and how to add internationalization. 

Additionally, I was asked how to deploy the frontend codebase and the backend server.
