Oracle came to my college in October 2021 for the role of Member of Technical Staff in their Server Technologies division.
Round 1: Online Assessment
The online assessment consisted of 5 main sections (All MCQs, No negative marking):
- Advanced Aptitude (Hard)
- Logical Aptitude (Medium)
- Data Structures Fundamentals (Medium)
- Most questions were from BSTs and AVL Trees in this section.
- Computer Science Fundamentals (Medium)
- English Comprehension (Easy)
All these sections had 4-5 subsections in them, each individually timed. You get 1-2 mins per question in each section except the Data Structures one, where you get 4-5 mins per question. The overall difficulty of the assessment was hard, because of the time constraint. 42 students were selected for further process.
Round 2: Technical Interview 1
- The first interview was mostly based on my resume. First, the interviewer asked me to introduce myself, then he asked me questions related to my project, which was web development based, so he asked me questions related to Web Development, JavaScript, CSS, etc.
- Then he opened up the Hackerrank collaborative editor, and asked me to write the code for the following questions:
- You are given a set of teams {A, B, C, D, E}, and you need to give a schedule for matches in between these teams, such that, each plays against the other team only once.
- This question was rather ambiguous as it was not mentioned clearly what I needed to give as result. But I was able to do it using two for loops and returning a list of pairs as the schedule for the matches. The interviewer was satisfied with my answer.
- I was asked to write a function to perform bubble sort, which I was able to do. ( https://www.geeksforgeeks.org/bubble-sort/amp/ )
Round 2: Technical Interview 2
- The second interview was based on my CS fundamentals. The interviewer asked questions from following topics:
- Computer Organization and Architecture
- OS
- FLA and Compiler Design
- OOPS
- I was able to answer most of the questions. This interview was very interactive.
After the second round of the interview, 12-13 students were shortlisted for the third round. I was one of them.
Round 3: Technical Interview 3
- This interview was to check my Ds Algo skills. The interviewer asked me the following questions.
- https://www.geeksforgeeks.org/maximum-profit-by-buying-and-selling-a-share-at-most-k-times/amp/
- I was not able to answer this question. After some time thinking, the interviewer himself said that, let’s do a simple one. Then he asked me this question:
- https://www.geeksforgeeks.org/remove-duplicates-from-a-given-string/amp/
- I was easily able to do this question. After this, the interviewer said that he was done and asked me if I had any questions. I asked my questions and the process was over.
They released the result the next day in the afternoon and selected 8 students. I was one of them. Hope this helps somebody
