NVIDIA Developer Senior interview questions

5 rounds of interview out of which three rounds focused on coding. Two rounds involved architecture and design. It easier if you have an internal reference. The architectural questions involved server design and deployment approaches. The second question was around finding the median of a trillion plus integers.

Applied online, got emails from recruiter after 2 months for 3 phone interviews and then followed by 1 day onsite interview. Interview went pretty good but not sure what they are looking for. I chased recruiter several time and always got response that they will get back within week. Never got Yes or No. Felt bad as I wasted 2 days for them.
