NVIDIA Developer Senior interview questions

Process was 1 phone interview then onsite after a week. Onsite interview was unorganized. Interviewers were not sure about the position they were interviewing about. Each interviewer had different perspective about the position. Very technical questions, it's more of sharing my experience and knowing about company and the product. Overall it is wasting every ones time. Suggestion: Be clear about what you want, before inviting for on-site process.
