Nutanix interview

I had two back to back telephonic interviews with Nutanix after initial assessment round. As per my analysis, the second interview went very well. In the first interview, i got less time in coding than brainstorming so could not complete the code, however, I partially completed it and told the interviewer my approach (even the code verbally). I was hoping for on-site call but got rejection. Hence, could anyone tell me how does Nutanix evaluate candidates?. I have asked for feedback too but not sure whether would get one.
