I gave only one round for Nutanix, 1st was DSA. The next scheduled were LLD and HLD and managerial.
My first round went really well, and I got good feedback after it.
Problem asked- https://leetcode.com/problems/increasing-triplet-subsequence/description/
I discussed Brute force, sub optimal and optimal approaches and finally was able to solve with the most optimal O(N) solution for the problem. Interviewer asked me to give running solution, it had one bug which I was able to find and give running code which he tested on all the edge cases that worked fine.
Then for scheduling the next round, the HR started ghosting me. After a week or two I was finally able to get a response and they said they moved forward with someone else.
Not the experience I had expected, but it is what it is.
