The first round in the recruitment process of Oracle was the written test. It was an online written test. The test consisted of 6 sections: logical reasoning, aptitude, programming, English and a 5 minute quick test. I cannot recall the 6th section. In 5 minute quick test section the questions were like finding the incorrect number in the given sequence of numbers or finding the next number in the given sequence of numbers and so on. In programming section the questions were from data structure and database management. However, not a lot of weightage was given to this section, even a candidate who had performed well in the other sections but not so well in the programming section qualified for the next round.
Oracle shortlisted 40 students for the interview round.
Interview:
Round 1: Personal Interview
In the interview I was asked some programming questions and some puzzles.
