Oracle Applications Software Developer I interview questions

The first round was online written test. There were 4 major sections. 1 was math aptitute, 1 was verbal (english) , 1 was basic computer and the 4th was advanced computing. They had questions on data structures, java, sql, etc. Verbal section had reading comprehension and other basic stuff. Math apti was kinda easy with ques on basic goemetry, speed time distance etc.Even though math section is quite do able, it is tough to manage time for this section. I got selected for interview. I found out that they majorly ask puzzles in the interview. But in the first round, they dint ask many puzzles to me. they asked me very hard coding ques but since I was from electrical background it was tough for me to answer them. But i answered the puzzles which was asked after that. I got selected to next round. In next round I was asked only high level maths apti ques.I managed to solve all ques but I dint get through to the next round.
