Interview Preparation Tips

Round: Resume Shortlist
Experience: I had a standard resume for this company as per the norms of our institute’s placement cell. For Oracle I laid emphasis on my programming skills and projects related to it.

Round: Test
Experience: The first round was the written test that comprised of 5 sections – vocabulary, aptitude, pattern matching, logical reasoning and programming. The questions in the programming section were asked from data structures and C++. The questions in the programming section were mainly from trees (from data structures). Around 400 students appeared for their written test out of which around 100 were shortlisted.

Round: HR Interview
Experience: The next round was the interview round. They gave me some puzzles to solve and a program to write. One of the puzzles that I remember was that if I were to be given an egg then how would I determine its durability, i.e. how would I determine that from which floor do I need to throw the egg from so that the egg does not break if thrown from any floor below it.
For the coding question I was given a mathematical formula and I was asked to devise a code such that the program uses the formula and gives the output.
Tips: Prepare for Data Structures as well as the commonly asked puzzles for Oracle.

College Name: IIT ROORKEE
Motivation: Oracle is a reputed company in the space of software and ITeS. It had come to our campus with five profiles. The best means to know about all of them is to attend the pre-placement talk of the company.
