A cold phone call from Internet phone and chatting quality was very bad. After going through the resume and my experience, the COO just asked tons of Behavior questions to know whether your personality or some unrelated stuff was a good fit for his company culture. However, he did not know any of the technical experience in your resume and did not care about your technical skills. No time for you to ask any questions, more like an interrogation and It's true. Showing no respect for the interviewer And finally a puzzle problem. No data structure or algorithm problems, Nothing even basic language problems I think he is looking for very very smart people who focus on business, not technology
