Oracle | SDE2 | Mar [Offer] | OCI

This was an internal transfer, I used to work for the pre-sales team at Oracle and I wanted to move to the development team of OCI. Job role - Software Engineer [OCI] So I started my prep on Leetcode, did about 3 months of solid preparation. I had 5 rounds.

Round 1:

• Top K Frequent Elements
• Generic APIs - Write a function like convert(function, input) input - binary tree output - binary tree and the function applied on it. ex(toUpper)

Round 2:

• Find First and Last Position of Element in Sorted Array input - [0,0,0,1,1,2,3,4,5,6], 1 output - 3
• Burn Binary Tree from Target Node (from Leetcode)
• Bunch of questions on OCI

Round 3:

• Reverse Linked List
• Middle of the Linked List
• Class implementation of Linked List Node
• Basic questions on Java Threads and OOPs

Round 4:

• Full round based on OCI questions:

  1. What is Load Balancer?
  2. What is a compute?
  3. How to use load balancer?
  4. Load balancer algorithms?
  5. Basic questions on Docker.

  This round was specially for me as my previous role was a solutions architect. They were purely testing my skills on the previous role I performed at Oracle.

Round 5: Manegerial + Behavioural (Bar Raiser Round)

1. Questions on previous projects
2. How to sell your product/ get people to test your innovations
3. Problems you faced while suggesting ideas
4. Scenario where your idea was good and implemented in the given product

Finally, I got the job and have been internally transferred.
