Oracle Software Developer interview questions

I sat for campus placement for Oracle.First round was online aptitude test questions consisted of quant,verbal ,logical(containing flow charts with blank boxes comprehend the step from the paragraph given about it ),and technical aptitude questions (mainly from trees) and some c i/p o/p questions.each section had their own individual timing .quant was of moderate level.technical question of trees were lengthy and time taking to comprehend. Results of this was declared the same day . The company then visited the campus 1 day later. next round were 2 technical and two hr rounds. In the technical interview all the hr was seeking for was a good and innovative approach towards the problem.He was not impressed if one gave a generic solution.Some puzzles and basic ds,oops concept and os related questions were also asked. Those who cleared this round went ahead for the second round this time too optimised solutions for problems like longest palindromic substring were asked.The last round was hr round,which is the easiest among all .basic questions about you,your goals, why do you want to work with us were asked
