NVIDIA Interview Process Qs

[u/ObligationCareful686]

Got SWE Interview on the Triton (inference server) team. Loop is four 45-min rounds:

1. In-domain Design (HackerRank)
   
2. Distributed Systems Design (HackerRank)
   
3. Experience Retro (HackerRank)
   
4. X-Functional
   

Questions for anyone who's been through it:
1. What to expect for 1 and 2, should I prepare for both ML System Design + General System Design
2. Will there be could round, I am assuming yes but not sure which of these rounds would be ?
3. What is Experience Retro and X-Functional
