Initial HR contact asked some good technical questions which was positively surprising. Next round was doing a code review which honestly was very simplistic for a sr/staff role but easily cleared. Next round was coding which was again a very simple problem but just not a good interview question in the sense that it wasn't very scalable to sr/staff role, and it felt very subjective and focused on style rather than substance. I completed the task but they flunked me without feedback so unclear what happened.
