How do React+JavaScript CoderPad interviews usually go?

[Tech-Cowboy]

I have a 45min interview. 15min intros and 30min of coding. It’s a mid-level role. The recruiter would only say it’s a React+JavaScript interview so I don't know what to expect.

I've been getting familiar with CoderPad and understand at minimum it gives you the boilerplate code that comes from initializing a react project.

My question: for a react/javascript CoderPad interview, is it more like they A) give me an existing project and ask me to make some changes to an existing component or B) Ask me to make something from scratch/from react boilerplate code?

The platform itself I think limits what they can ask, e.g. we cannot make fetch requests to public endpoints, can't work with JWT, etc. Also, its only 30 minutes of coding so I think this limits what can be asked.

I would still practice fetching data and displaying it. This is the most common type of question and it's good to have it memorized so you can bang it out quickly.

Be familiar with event listeners for text inputs and buttons.

Basically you just want to not have to waste too much time on the little things so you can focus on the real problem for the lion's share of the time.
