Pattern
=======
30 qns. technical - 30 mins. - mostly on DBMS,
Oracle(like what would be the output), C, C++,
Java(2-3 qns. on class and constructors) and data
structures.
30 qns. general - 30 mins. - 7 qns. aptitude, more
like English (filling up prepositions, same meaning,
reading comprehension, four sentences would be given -
you have to order them to form a paragraph, similarly
four questions would be given - you have to say which
one is a inference statement, which one is a
judgement,etc.)
The technical test would be easy and general test
would be little difficult.
In the interview, they asked me the following
questions.
=============
1. what are the macros other than C macros (the macros
in word,excel)
A macro in MS-word is used to group a sequence
of jobs and make it as a button or keyboard shortcut.
Suppose, if you need always to draw a table containing
2 rows and 5 cols, you can start,record a macro and
make it as a button and put in taskbar, sothat when
you press it, you will be provided with a fixed table.
2. can you delete a column from a table.
In oracle 9i, you can do it by the statement
ALTER TABLE table1 DROP COLUMN column1; In oracle
8,you can't.
3. can you store a image in oracle and by which
datatype?
Yes, you can and it can be acheived by using
a BLOB (binary large object) type and store upto 4GB
in a single column.
4. have you used reports and forms in oracle?
5. have you written applications to retrieve stored
images in a table?
6. some DOS commands and UNIX.
7. project desription (both academic and
miniprojects,if any)
8. some situation questions like what would you do if
your company is burning,etc.
Please have a look on DBMS, and some simple
queries like 'select * from dual' for the technical
test. And on the questions in the attached file. All
the best.
with wishes,
sakthi.

june 21st Oracle Bangalore test .. some questions from 9' O clock
batch.
Oracle conducted test for freshers at bangalore in their campus (near
Diary circle).
it was of 4 rounds as I know(9 AM,11AM,1PM,3PM O clock).
question paper consists of 60 questions.
QUESTIONS FROM 9 AM round
30-english and aptitude
30-SQL,C,C++,JAVA
NOTE:
I met some people who attended the test..
i am putting the details..
Please do not assume the questions as accurate, there may be some
mistakes and for some questions there may not be full options or no
answer.
My purpose is to give an over all idea about the question paper so
that it will be useful for others..
English:
analogy questions around ( you can refer to GRE book)
fill the sentence with appropriate word..(multiple choices given)
sentence correction..
Aptitude:
arithmetic questions..
some of the questions:
Q:1/3th of the passengers gotdown at first stop and 30 people got
into the bus,
1/4th of the passengers gotdown at second stop and 12 people got
into the bus.
in last stop 84 people got down from the bus.
What is the initial capacity of the bus?
Q:one person is running around a 180 sq yard filed, first 1/4 his
speed was 10KMPH second 1/4 20KMPH third 1/4 30 KMPH and the fourth
1/4 40 KMPH.
what is the average speed?
NOTE: there was a question on milk ,water ratio..
logical deductions..
Q: is x+y a prime?
a. x is prime
b. y is prime
options: 1. only "a" correct 2. only "b" correct 3. both are correct
4. both are wrong.
C,C++,JAVA
Q: There were 2 or 3 C programs and the question is to point error in
the program or to predict the answer
Q:Which one of the following is not a storage type:
1. static 2. register 3. stack 4.auto
answer: stack
Q:what is the type of the second parameter of fopen() function?
Q:Which of the following is correct about constructor?
OPTIONS: 1.void type 2. return nothing 3..... 4.....
answer 2
Q:how do we store a constant value in java?
multiple choices given..
answer: using "final"
SQL:
please be thorough with SQL, PL/SQL
There were some questions where they gave query and asked whether it
is correct or wrong if wrong what is wrong...
Q: create table...........;
{table creation query)
Roll back;
what will be the output?
options ....
This is all that i was able to get!
my view:
I think if we spend atleast 1 month seriously dedicated, then we can
clear Infosys or Oracle test with out much problem...
YOU KNOW YOU CAN DO IT
ORACLE
I attended the oracle walk-in chennai,But i failed. My exp. will be help ful for u in the future.
Test is 30 min,30 Quetions.Questions are simple. But,I think that they expect higher cutoff
i.e. above 28 is to be answered corretly.
* some questions are Code Snippet based.
* Some questions are compiler based i.e. given code snippet will compile or not, if not the
reason.
* some question are from the prfix/postfix inc/dec operation based code snippets.
* More than 3 question are based on the sorting algorithms.
* some questions are from the pointers based.
* Code snippets involving memory allocation function.
* All the questions are from c
Some of the question ,i remember, are the following
1.
#include
#define sqr(x) (x*x)
int main()
{
int x=2;
printf("value of x=%d",sqr(x+1));
}
What is the value of x?
a)4 b)5 c)None d)can not compile
Ans: 5
2. what is the wrong in the following program?
#define LBRACKET {
#define RBRACKET }
#define MAIN main
int MAIN()
LBRACKET
int x=2;
printf("%d",x);
RBRACKET
a) This program will compile
b) compilation error
3.
#include
int main()
{
int x=4;
{
{
{
int x=2;
printf("%d",x);
}
}
}
}
a) 4 b)2 c)Nesting not allowed d)dependent on the compiler
4. Go through the following code sinippet
char a[20];
a="Hello Orcale Test";
will this compile?
a) Compilation Error b) Strings are allowed in c but cannot be assigned directly.
c) dependent on compiler
d) will work fine.
5. the expression a+b*c should be conveted to +a*bc. Using tree structure,
Which traversal is the correct one?
a) Postfix traversal b) prefix traversal c) infix traversal d)None
6. what about brk, sbrk
a) system calls b) function calls c) user defined functions
7. Why the use of alloca() is discouraged?
8. Macros support multiple arguments ?
9. the header file
a) contains only compiler directives and extern variables
b) contail only structures and unitions
c) a & b
10. what about "char *(*(*a[])())();"

Yes. And Sanjay Patil, who was porting Oracle to SCO-Unix has already
gone to US! A good company, but only if you are willing to condemn
yourself to working in Oracle all your life. They work in all aspects
of Oracle, right from the internals (file system, concurrency control,
etc) to the User Interface. Quite a lot of their work is bug fixing
and stuff, but some lucky fellows might get to do a bit of porting
from one OS to another, which isn't as bad as it sounds, actually.
