Toptal Software Engineer Interview interview questions

The online interview took place by Bluejeans, which is zoom like but not good to use. First Screening is done with codility and there are 3 questions that need to be done within 70 mins. The interviewer is a senior engineer. Firstly, the interviewer asked me where do I live and some basic questions, but the interviewer's mood is extremely bad and did not show basic respect with a person. Because of the online interview, the interviewer asked to look at the middle of the camera, otherwise he would doubt you read something.
