Oracle OCI | MTS (IC-2) | Bengaluru

Current Experience : 6 months SDE intern @ Amazon
Position: OCI - IC2
Location: Bengaluru

I really loved the Interview experience at Oracle. There were 6 rounds in total. All the interviewers were very helpful and professional. The process is very smooth. All interviews were completed within span of 1-5 days.

Technical phone screen (1 hour):

This is a screening round.
Subarray sum equals k
Bottom view of Tree (because time was left)
1 SQL query (because time was left)

After 3 days I got the call that you have qualified screening process and we can schedule interviews after 1 week.

Loop Round 1 (1 hour):
count number of pairs(a,b) such that a+k = b.
Input: Unsorted array
k = integer

Loop Round 2 hiring manager (1 hour):
Discussion around internship for 30 minutes
egg drop puzzle

Loop Round 3 (1 hour 15 minutes):
LRU Cache
Questions around internship work, CN, DBMS, Hashing, Github, OOPS, and some behavioural questions.

Loop Round 4 (Bartender/Bar raiser) (1 hour)
The interviewer had 20+ years of experience.
Initially some questions around Cloud architecture, then behavioural questions, and then combination of technical + behavioural.

Loop Round 5 (1 hour 10 minutes)
He expected the interview in this way:
intro - 10 mins
2 LC hard in 35 minutes
Project discussion - 10 minutes
feedback/ questions - 5mins

First missing positive( he expected some approach, I also did it in optimised way, but he wanted that i should also do by his approach only)
At end I gave pseudo code of my approach.

He expected that after these 2 questions, we will have discussion about projects, but time was over.

I would say overall interviews went well.

EDIT : I cleared the interview and got selected, but HR said opening is on hold, fml
