Interview preparation tips for other job seekers - Overall good

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.
