Candidate #1: Oracle Interview Experience for Freshers

Job Role – Member of Technical Staff

Status – Selected

A while ago Oracle has conducted recruitment on our campus to onboard the final year students for the Member of Technical Staff (MTS) and Application Engineer positions. Now, check out my Oracle Latest Interview Experience to know how the whole process went for me and what questions I’ve faced at the time of my interview.

Round 1 – Online Test/ Written Test

This will be a screening round, for candidates to get shortlisted for further rounds you need to perform exceptionally well in this Oracle Online Test round.

The Oracle Online Test has compromised of Aptitude & Technical MCQs. For aptitude basic quantitative & reasoning topics were covered. While coming Technical questions, questions from Data structures, OS, DBMS, Networking Concepts, Flow Chart Analysis, and other questions from core subjects were covered.

Note: There will be a time limit for the online test and you need to complete the exam well within the time.

Once I’ve successfully completed the online exam I got the result saying I’ve passed and along with me 40 other students were shortlisted for both roles.

Round 2 – Technical Interview Round-1

I was slightly nervous in this round, but the interviewer is very friendly and he observed my nervousness, and just to make me comfortable he asked me about the online test (How it went and all, which section I’ve performed well). Then next, he slowly started asking questions about my core subjects & my projects. To get an idea about this round, check out the Oracle Technical Interview Experience I’ve given below.

1. Explain the Dijkstra algorithm

2. What are transactions and how to implement them in SQL.

3. Explain LIFO and FIFO with examples in real life.

4. Difference between overriding and overloading.

5. Types of loops and their uses.

6. Given a scenario which Join would you use and why.

7. Use of volatile keyword in C++

8. Given an array of n numbers, find any number which is not the greatest in the array in O(1) time. (Just compare the first two terms and return the smaller term)

9. Which data structure is used for function calls and recursion.

10. 2 basic SQL queries

Round 3 – Technical Interview Round-2

First, the interviewer asked me to introduce myself (Talked about my educational background, projects & Internship experience I had, briefly about my family). And here are some of the technical questions that were asked to me in my round 2 technical interviews.

1. Write a class in C++

2. Write a copy constructor

3. What is operator overloading and write a code for it.

4. Write a factorial function using recursion

5. Explain Kadane’s algorithm.

6. Name the six steps involved in SDLC.

7. What are the four pillars of Object Oriented Programing Paradigm

8. What are the necessary conditions for a deadlock to occur in an operating system.

9. Name all OSI Layers

10. Name some methods of concurrency control in DBMS

Round 4 – Technical Interview Round-3

1. Again the interviewer asked me to introduce myself.

2. Asked me to explain Dijkstra Algorithm.

3. Square root of an integer (Given an integer x, find its square root. If x is not a perfect square, then return floor(√x).)

4. Square root of a number using the Prime Factorization Method.

5. How we can secure our data by using encryption and OTP.

After a fruitful day, I got my result stating that I’ve been selected for the Member of Technical Staff job position.

Candidate #2: Oracle Interview Experience On Campus

Job Position – Software Development Engineer (SDE)

Status – Selected

A few days ago Oracle has come to our campus to hire eligible candidates for the Software Development Engineer position. And I was one of the candidates who appeared for the interview.

Below is the recruitment process that I’ve gone through.

• Online Test
• Technical Interview 1
• Technical Interview 2
• Technical + HR Round

Round 1 – Online Test (Aptitude + Technical MCQs)

I felt this round was a bit difficult. General aptitude & reasoning topics related questions were asked and Questions from DBMS, Computer Networks, OS, Data Structures were covered in the Technical section.

Round 2 – Technical Interview 1

For me, the technical round is conducted through the Zoom platform. Foremost, the interviewer introduced himself and told me about the position he works at Oracle and then asked about me (My educational background, my projects & other details). And after some time he asked basic questions about my technical subjects. The whole interview lasted for 40-50 mins.

Here are some of the technical questions that I’ve faced.

1. Difference b/w Interface and Abstract Class.

2. What is Memory Leak?

3. What is Dangling Pointer?

4. What is this Pointer?

5. How to allocate a 2D array dynamically?

6. What is Copy Constructor and Destructor.

7. What is Multiple Inheritance

8. Explain Operator Overloading and Function Overloading. (Write a code)

Round 3 – Technical Interview 2

This round is also conducted on the Zoom platform. The interviewer generally asked me about previous rounds and what I felt about them. And then, he asked me to share my screen & open an online editor. Where he asked me to write code for the following.

1. Detect and Remove Loop in a Linked List (Write a function detectAndRemoveLoop() that checks whether a given Linked List contains loop and if loop is present then removes the loop and returns true. If the list doesn’t contain loop then it returns false.)

2. Delete a node in a Doubly Linked List (Write a function to delete a given node in a doubly-linked list.)

3. Implementation of Heap Sort

4. Inorder Tree Traversal without recursion
Step -1) Create an empty stack S.
Step -2) Initialize current node as root
Step -3) Push the current node to S and set current = current->left until current is NULL
Step -4) If current is NULL and stack is not empty then
a) Pop the top item from stack.
b) Print the popped item, set current = popped_item->right
c) Go to step 3.
Step -5) If current is NULL and stack is empty then we are done.

5. Recursively Reversing a linked list (A simple implementation)

6. What is Inline Function?
