Oracle Interview Experience for Software Engineer

This process is after clearing Online Assessment and getting qualified for Oracle Interview.

Round 1 :

The interviewer first asked me to introduce myself and go through my resume.

After this some random chit-chat like how is your day etc.

I completed my Introduction and then he asked me to say which programming language I am comfortable with and asked me to rate myself out of 10 in DSA Skills.

Then Interviewer gave me a DSA question and asked me to share my screen and solve the question step by step by explaining the idea.

Here is the question.

Question: You are given an Array A of size N where A[i] denotes the strength of ith person and you are also given two integers m and k. You need to find the number of distinct groups you can form which have a size of at least k and all the persons in that group must have strength more than or equal to m.

Then I first explained the approach and then wrote the code.

After completion of the code, as one of my projects is related to ML so he asked me a few questions related to ML. Like What are the basic steps all need to follow while doing an ML project etc.

Round 2 :

In this round, I was again asked a DSA question which is just a standard Stack Question (Parenthesis Checker), and then asked a few ML-related questions like what is variance, what is pruning, etc.

Here the interviewer is so friendly.

Round 3 : 

In this round at first, he asked me to say about myself and then he asked me whether I have an idea about recursion or not. Then I said that I have an idea of recursion.

Then he gave me a question to write in recursion.

Questions Write a recursion function that will print numbers from 1 to n and the same function must go from n to 1. Note: Not to print n to 1 while the recursion function is returning.

After writing the code he gave me an Aptitude question to solve.

Question: You bought a book for 10 Rs and sold it for 15 Rs and again bought the same book for 20 Rs and sold it for 25 Rs. What is the profit you earned from it?

I told the answer and he asked me to say the approach and how I solved it after saying my approach he asked me to think of another approach and I thought for some time and told another approach then he told me that my answer is correct and now can you try for another approach and I tried for some time but I was unable to get another approach and then he said to leave it and wrapped up the interview.
