Turing interview questions

I scheduled a zoom interview at this company, on the interview day and a day before the interview, I received what I think are automated emails (from calendly.com) reminding me to make sure I get a quiet place, good internet connection, etc. After creating time off my schedule for the interview, I had to wait for the interviewer who did not show up in time for the interview. Eight minutes into the interview time, the interviewer canceled the calendar invite. I then contacted him (the interviewer) to inquire why the invite was canceled and whether or not we will have the call/reschedule it of which he informed me know that the interview was canceled because "I was not fit for the role". I think it is best if you let someone know before so as to avoid wasting someone's time on an interview that will not happen.

It was a code challenge interview, when the time came the interview starts immediately, it was something like Leetcode problem challenge, there was no guide to get you familiar with the framework, the counter starts immediately and there was no interviewer which I didn't expect, just six minutes before the time end I realized that there are two problems instead of one, they gave no details about the interview before it starts.
