J.P. Morgan Derivatives Clearing Operations Analyst interview questions

Hiring process was such a rush. HR would rush you for an interview and sounds unprofessional in dealing with candidates. Hiring manager interview was cancelled on the spot and asked ro reschedule on the next day right away(making it sound like they are on a rush). Rescheduled interview was booked and was made to wait for more than 20 minutes in the call then receive a call from the HR "rudely" telling me I have an interview at this time and where am I? Out of nowhere the hiring manager shows up uninterested with the generic question "tell me something about yourself", they are blankly staring at my resume pretending to take down notes and most of the time too much silence from their side. By the circumstance I could obviously tell I was just a candidate to fill in the quota. Not new for the hiring practice of the company.
