Oracle Ltd. recently visited our campus for the role of the application developer. There were a total of 5 rounds (online test+3 tech interviews+ hr interview).
The level of the questions was above average.
Out of around 70 students, 40 were shortlisted for the personal interviews.
- What if the difference between class and structure ?
- Why use class when we have structure?
- What are the differences between c and java?
- What is the feature that makes java platform independent?
- Detailed description(steps) of how a java code is converted into machine code.
- 3 coding questions (complete code was expected)
There are a sequence of words and the limit on the number of charachters that can be put in a line is given as 80. write code in a such a way that the given sequence of words is properly partitioned (after 80 characters
in a line, a new line has to be started ) condition:- no word has to be split (partial placing of a single word in 2 adjacent lines is not allowed).
Example:– if the sequence is “hi iam abc iam from xyz” and the limit=7, then the output should be:-
hi iam (7 characters last character is space)
abc iam(7 characters)
from (had to split xyz entirely to the next line because “from xyz” crosses the limit 7
– Modified Minimum cost path in a matrix (dynamic programming question).There is a matrix with positive and negative integers and few cells with “X” characters through which the path cannot be taken.
*Code to find the minimum cost from (0,0) to (m,n).
*Code for the actual path from (0,0) to (m,n) through which the cost is minimized (the optimized solution was expected).
-There are a sequence of characters like “ABBAAADDEEBBD”
*sort them on the order of occurrences, maintaining their order in the given string.
output :- AAAABBBBDDDEE
- Questions on internship project.
- How much would you rate yourself in coding?
- 1 coding question (complete code expected)
There is a bus stop where people have to form a queue. People forming the queue are numbered in the increasing order and are labeled with a character “E” or “B” where E says the person to stand at the end in
the queue and B says that he should go to the beginning. If in the queue any person with bigger number stands in front of any person having a smaller number then the person with a smaller number raises an
“unsatisfactory count”. For an input, string count all such unsatisfactory counts of all the persons.
Example:- input string “BEEB”.
output: -1110, because 4th person has got the label ‘B’ so he stands in front of all the first 3 persons… so all the 3 persons raise a count for the 4th person standing in front of them.
- 1 Database question
There is a car showroom which sells or rents cars of different models. A particular car model may have many number of cars (like there can be 20 Maruti alto cars). A customer can buy a car or take it for rent if he
buys a car then the total number of cars of that model has to be decremented by 1 but if a car is taken for rent the number should not be decremented.
*Interviewer:- Now, considering all the cases and conditions design a database for the system ( he intentionally did not mention any )
**so I had shown 3 tables with all possible columns, an E-R diagram for the system, a sample J2EE servlet code and few possible SQL queries)
- Write a recursive function for finding factorial ( all base cases were expected ) (this question was asked just to test my speed )
- Why is your cgpa decreasing ?
- What is your favourite subject? to which i replies mathematics
- If you have 5 0’s and can choose any mathematical operator … get 120 out of those 0’s
- Discussed about work at oracle in detail.
- Questions on internship project.
- Tell me about yourself.
- What are your strengths?
- What are the areas in which you think you have to develop?
- Give a location preference .
- Why did your cgpa drop so drastically in the fourth semester?
- What are your hobbies?
Finally , they selected 7 students .
