J.P. Morgan Data Scientist interview questions

The job was open in March on linkedin.I was interviewed by Hiring Manager in April. After i passed this round, I was supposed to have an interview with the ED. The interview was reschdeuled by atleast 3 times by the HR. Then, they scheduled it and when i joined the call, the ED did not join for 20 minutes and i left. Upon querying HR on ths, they told me that they are still reviewing the details of the JD and will reach out to me once confirmed. Its been 3 months and when i checked the status on their career portal, it says "not sected"

Interview was straightforward, online coding challenges with video explanation for your answers. Hosted via Hirevue. Follow up with a superday, three interviews for a total time of three hours back to back
