JP Morgan HRs are not responding regarding the interview status after the final round. How should I handle this?

I attended an interview with JP Morgan, and the HR team was responsive to my emails regarding scheduling and other communications until the final round. However, after the final round, they have not been responding to my calls or emails regarding an update on the interview process.

It has been 10 days now.

Should I assume that I was rejected in the final round, or does the evaluation process typically take this long?
