Video interview in Nigeria is like NTA. You will surely have lines breaking even if from your end all is well, the interviewers don't care aside from starting very late. Next thing is unsuccessful email.
I once had an interview with someone in the US. Aside from choosing my own time, we started exactly at that time and it was like we were beside each other. The experience was really nice.
Why don't interviewers care about time and quality of their interview?
