Perguntas de entrevista da empresa Simform

They have scheduled one hour interview with CTO , and he asked me 10-15 questions very rudely and when I finish answer of any question(most of them are right) he is not going deep in particular question and just asking random another domain question and he finished interview in 15 min without any discussion about projects and all. And they rejected me that I don't have research level algorithm experince. I mean if you are not asking research level questions how you can reject someone without evaluation on medium and hard level ..it was very rude and unprofessional experience will not recommend anyone for this company
