Next Order Senior Frontend Engineer interview questions

In the first call the interviewer didn't appear. The HR didn't even revert back or mentioned the reason. They had one technical round by a third party recruiter. I didn't like the approach. Within 1hour of interview they were trying to cover js problem solving, system design, html css design and javascript questions. Everywhere else all these are minimum 2 rounds. I felt the interviewer was unable to explain requirements properly due to such short time.
