Interview Preparation Tips

Round: Test
Experience: Oracle had an online test which includes 3
Sections:
1. Programming: basic C++/java programming + data structure. One need to have good hand over oops
to score well in this section.

2. Aptitude: General Aptitude Questions

3. General Maths: Very simple maths problem (+2 level) but needs very very good speed.
Tips: Individual cutoff was not declared, but different cutoff for different profile is expected.
Oracle has no GD round.

Round: Interview
Experience: In 2nd round of interview, there was more programming, less resume based question and more emphasis on will I be comfortable in an IT sector. Some apti questions were also asked.

Round: Interview
Experience: 1st round was completely on resume based. Each and every project and intern is discussed in detail. Most of the extracurricular activities were also discussed. In the 1st interview, some basic program like fibonacci series by recursion, star pattern by loop etc were asked.

College Name: IIT Roorkee

Interview Preparation Tips

Round: Test
Experience: The sections were Quantitative, Logical, Verbal and Computer Science.The three sections contained very basic questions of general aptitude while the Computer Science section contained questions on Database Management, OS, SQL and Programming Aptitude.

Round: Test
Experience: The question was to program a logic to test the correctness of a solved sudoku. We were allowed to code in C++, Java, C or pseudo code.

Round: Technical Interview
Experience: Were asked simple questions and program them like reversing string without temporary variables, finding the earlier date when entered as string and finding the difference in number of days between them.
I was asked to explain him my internship project in great detail and above all one should be prepared to answer the question 'Why IT?' if from a non IT background. Then I was asked to program a logic for 'Search and replace" tool of MS Word.

Round: HR Interview
Experience: Was asked about my background in detail and stressed again and again on 'Why IT?'. Then he asked me to prepare a summary on the merits and demerits of various Employee Data Management techniques for an organisation. For the end of the interview you should have a question which you would ask to the interviewer.

General Tips: Don't try to over emphasize the correctness of your logic if the interviewer finds a glitch. It irritates him. Be interactive in your HR round. In our case it was the VP of Oracle India who took the final round. So I asked him about his experience in the company. He was very happy to share it with me. But asses your interviewer before you put forth these queries cause your interviewer might not be as jolly as mine was.

Interview Preparation Tips

Interview preparation tips for other job seekers - Total pathetic experience. Have heard of negative reviews from a number of people, but didn't believed. Unfortunately had to share same pain with them. What job description is given to you, doesn't matters because you won't be asked for that. Your resume will get shortlisted and then it doesn't matter what u have covered up in your career path, because interview rounds will consist of questions out of your scope. Your resume doesn't needs to be shortlisted at first end if it doesn't suit thier needs. HR people, they are on another level. You share your resume to them, and they will never ever reply back to you. Not a single HR, but it seems everyone has same culture. You keep trying to connect them for support. But they will just keep finding smarter ways to avoid.
