Oracle Interview Experience for Associate Application Developer (On-Campus) 2023

During the placement season, Oracle visited our college (MIT, Manipal) on August 2023, The CG cutoff was 7, and around 350-400 students took the Online Test.

ROUND-1 (Online Test)

• The first round comprised 20 MCQ questions including aptitude, logical, and mathematics (Test Duration: 1 hour 30 minutes).
• MCQs were mostly puzzles, probability, and some aptitude questions.
• 2 coding questions – The first question was on string manipulation – The longest increasing subsequence string, The Second question was on REST API – https://www.thejoboverflow.com/p/p1439/ .

ROUND-2 (Technical Interview – 1)

40 students were selected for a physical interview, there was a PPT before the interview process. For all, the interview duration was different mine was 1 hour 15 minutes, each interview round started with a brief introduction, and in each round the interviewer was different.

• Questions from my projects. I had 2 projects, My first project was on DJANGO, so he asked various typical questions on DJANGO such as why DJANGO, did you solve any real-life problem, how did you solve it, is there some changes you still want to make in the project, give an overview of the project and then he asked me to write some functions from the project I guess he was not convinced that I build the project but whatever the reason might be I wrote 2 functions from the project and explained its working.
• My second project was a JS API-based weather application, he asked me what the APIs I was using were and how I was using them.
• Then he asked me some questions on OOPS like what are the 4 pillars, explaining all the pillars with examples, and some questions on class object outputs.
• The remaining questions were from basic C++ like what stack overflow, and explaining different types of memories he asked me if I was familiar with Linux but I wasn’t so told him no, Lastly, he asked me if I had any questions if I wanted to ask him.

Tips: Explain using pen and paper, revise your projects thoroughly and prepare at least 3 subjects from OOPS, CN, OS, and DBMS, practice DSA thoroughly for at least till trees, not me but most of the other students were asked questions from linked list such as remove loop, find intersection of 2 linked list, add 2 number represented as linked list and store the answer in another linked list with a condition of no reversing allowed. (I used 2-3 total pages in this interview).

ROUND-3 (Technical Interview – 2)

Around 30 students were selected for this round, my interview duration was 45 minutes.

• The interviewer asked me questions on OOPS, Again some questions on function overloading and overriding.
• 1 DSA question on string reverse using the GREEDY method.
• Then some questions on pointers and reference variables.
• Some CN questions like what is the size of IPV4 and what are the 6 OSI layers?
• Lastly, he asked me if I had any questions, I asked him how my interview went, and he answered it went well and I explained everything nicely.

Tips: Again I will recommend everyone to explain everything using pen and paper.

ROUND – 4 (Technical Interview – 3)

This round was 35 minutes long.

• One puzzle was asked – Find the fastest 4 horses with a minimum number of races if there are 36 horses and 6 horses can race at a time.
• He asked me if I was familiar with OS, and I said that I was familiar with CN, OOPS, and DBMS, and as my branch was ECE so he was satisfied.
• Lastly, he asked me some probability questions, till now for every interview had answered all of the questions correctly but then he confused me with a pointer and reference output question for which my answer was wrong Again he asked me 1 more question which was about pointers and class related and I panicked and again answered incorrectly, he even said I guess you are weak with pointers.

I thought my interview was finished and I will not qualify for the next and final HR round but I did.

ROUND – 5 (HR Interview)

This round was 10 minutes long.

• She asked me to introduce myself and asked about my parents, siblings, and my hobbies.
• Lastly, she asked what is your preferred job location for which I said I was open to any location.

The whole interview process took somewhere around 9 hours 10 AM to 7 PM.

I got the mail 3 hours later. A total of 7 students were selected as Associate Application Developers.

All of the interviewers were very kind and most of the time I felt they wanted me to answer all the questions correctly, They also gave me some hints when I asked for it.

I hope my experience helped some of you, All the best for your placements. 🙂
