Oracle Interview Experience (Full time) | On-Campus 2020 (Virtual)
College/University: Indraprastha Institute of Information Technology Delhi (IIITD)
Oracle visited our campus in December for M. Tech and B. Tech students and
it was all virtual because of Covid-19. I am Rahul Maheshwari and I completed my M. Tech from IIITD.
CGPA cut-off required: 7.0
Round 0 (Online Test): This was a preliminary test that covered questions from Aptitude and Core CS Subjects (Network, OS, Database, DSA). The test was around 90–120 mins long and was a little bit challenging as it had different sections and had sectional cut-off. Out of 155 students, 36 were selected.
Round 1 (Online Assessment + Technical Interview): Round duration was about 35–45 mins.
First, the interviewer asked about me and had a look at my resume. He asked about one of my projects mentioned on my resume and how I stored the data being used in the project. The technology stack that I am familiar with and he asked me to explain what is NLP (natural language processing). Then he asked about some of my published technical articles that I wrote during my undergrad days. There were questions from CS core subjects like DBMS and OS, most of the questions were about Linux. A coding question was asked about finding and removing duplicates in a Linked List efficiently. Language choice of C, C++, Java was given. Sufficient time was given as I had to first explain the logic and then write code on the shared notepad. 25–30 students were selected for the next round.
Round 2 (Technical Interview): Round duration was about 30–40 mins.
Once again the interviewer talked about my technical articles which were published on a popular programming website and gave me a coding question similar to one of the articles I have written about. The problem given was to reverse a string in which each word is reversed maintaining the order of words without using any inbuilt library function. I managed to eventually write efficient code for this problem as enough time was given to me by the interviewer even after facing runtime errors in a few tries :D. The interviewer was very supportive and friendly.
Round 3 (HR + Technical interview): Round duration was about 30 mins:
The interviewer asked me about Cloud and oracle products, what is and how to implement Single Sign-on functionality which I was able to answer close to the correct answer but not exactly on point. In my opinion, the interviewer wanted to know my approach to a problem that is new to me.
Finally, he asked me if I have any questions for him for which I asked about his personal experience with Oracle. 13 out of 30 students were selected.
Verdict: Selected!

Note: Interviews were conducted virtually on Zoom.
Tips: Be confident while answering and believe in yourself. When asked to code first think and tell them your logic, so they can know your approach. Don’t directly jump into coding. Start coding when the logic is completely clear to you. You can ask for some hints if you find the given problem very challenging or stuck at some point. Don’t beat around the bush when asked about something. Give honest and correct answers or say no to a question if you genuinely don’t know about it. Maintain eye contact with the interviewer and try to maintain a constant pitch and tone.
