EMR Group Limited Senior Software Engineer interview questions

It consists of few assignments round and then 1 technical round and then last technical round. I am 200 percent sure I have given all answers correctly for the last technical round like 💯 sure. But I got rejected by stating it was a close call wait what close call which I don't understand person can give 100 💯 answer to question what else I can do in the interview.. One person from US and One is from UK. It seems more like being pre judgement of not selecting the correct candidate even when you answered the all questions correct. They would have saved my time and also been quicker just entering the call and rejected there itself.
