round-1 online - Principle SDE : Online multiplayer gaming design

onsite:
round 2 - hiring manager : questions about past to check if can fit mentor role (seems got rejected here)

round 3 - SDE 3: Design hackerrank like system

round 4 - SDE 3: Design #@#@$!!!@ [still dont know what he was asking to design] ... I guess Shopify like system

round 5 - SDE 3: Design outlook scheduler like system

online round 6 : coding [this was predecided even before interviews started]

1. max average subtree in N-ary tree
2. Maxium sum pair in array with sum <= k

Any idea on how much is aceptance ratio for SDE 3 interview in Amazon India ... I was told "Its easy to get SDE3 in Amazon from outside" so I am surprised by rejection. Performance was above average only as told by Amazon recruiter.
