With Clarity interview questions

I have received an email to interview for the front end design internship position. The person who was suppose to call me forgot we had a phone interview, so we scheduled. When trying to reschedule, they suddenly became unresponsive and became so spontaneous and scheduled it the next day I emailed a follow up. Once the date of the rescheduled interview came, the interviewer did not even call or send me an email before stating whether or not the interview is cancelled.
