I recently finished the onsite for OCI and thought about sharing my experience here.

(Tech Screen)

This was 1 hour screening round and it started with some questions about my past experience. Then for the next 40 minutes, I was given a problem to solve. It was a leetcode hard problem. I explained the approach and wrote the complete code and the interviewer gave some hints and was able to run the code successfully.

(Onsite)

There was a 5 hours of onsite scheduled with 2 breaks.

Round 1 :
It was a coding round. After the initial behavioral questions, I was given a coding question to solve. It was a leetcode medium (tends toward hard imo). I solved the question but took the complete time, there wasn't any time left for Q&A.
Round 2 :
It was a system design round. It started with behavioral questions and then I was given an ambigous statement of "Design xyz system". The interviewer was friendly and asked me a lot of counter questions and helped me at many places.
Round 3 :
This was again a coding round. This also had few LP style questions. Post that I was given a coding question (leetcode medium) and it was a simple one and I coded it quickly after explaining my thought process and solution. Then the interviewer added another question to it (again a leetcode medium). I explained my approach and coded that. Then the interviewer asked me some follow up questions about the code. Overall, this round went really went.
Round 4:
This was a bar tender round and it was mostly a behavioral round. The interviewer asked me many questions regarding my past experience. At the end, i was given a simple problem to solve.
This round also went really well.
Round 5 :
This was the round with the hiring manager. It was mainly about my past project experiences and I was really grilled about anything that I said.

The overall experience was really good and I would like to give few tips if you're appearing for OCI interview :

Prepare all the Oracle tagged questions on Leetcode (especially medium & hard).
Go through all the popular system design questions (if you don't have any prior design experience)
Know your past projects really well. Prepare with all the counter questions.
OCI really values its principles and prepare multiple stories about each OCI values.
