JP Morgan SE 3 interview experience

Summary
I interviewed for a Software Engineer 3 role at JP Morgan, but was rejected after a React-focused round.
How it went
I got a call from HR to attend SE 3 through one of the job portals without referral.
I was very excited for interview since interviewer was less than my experience too.
But there was no clarity on the type of first round from HR on whether it is DSA or JS related before.
I was expecting DSA questions but all of them were React JS related...
I was asked to change the background color of divs using useState and useRef hooks based on value added in input field.
Struggled a bit with useRef hook usage to attach the color input value to div due to use of AI tools in day to day coding activities in job.
Then, I was asked to solve a machine coding question related to fetch api usage in useEffect hook with jsonplaceholder api and display it as list of thumbnails with titles.
Few useEffect dependency array related questions were asked while solving this.
I was rejected after this round... might be due to low confident answers and minor conceptual errors in answering.
