Oracle Member Technical Staff interview questions

I had two rounds of 1:1 technical interviews by regular employees followed by a semi-HR-Tech interview by a senior member in the team. This was then followed by a final HR interview which seemed to be mostly a formality. Round 1: Basic Algorithms on linked list & Hashing and some OS questions. Round 2: Intermediate Algorithms related to trees & Graphs. Round 3: Casual discussion on future plans & technological interests.

Approached by Oracle member of recruitment team. One technical test held the next week. Interview held in the same week Friday. Offer released in 1 month after that.
