PAPER 2

The test was of 1 hour 30 ques. g apti and 30 of
technical.......some
ques. of g apti were very lengthy so don,t end up in solving
them.....time was less......some 15 ques. from arithmetic......and
rest
15
logical,statement interpretation,arrangement,tense
correction......and
like
that......
i am enclosing here the 2 C questions :
1. given a square matrix which consists only of 1 and 0......find
which
rows,which cols and which diagonals consist entirely of 1,s.
2. given an array of integers find all possible combinations of
the
numbers whose sum equal to 90.....
ans : knapsack problem (in data structures - aho ullman)
Note : for them solution was not the criteria.......but the
approach
was important......the solution should be generalised and
optimized........optimization was given the top priority........
here is the techincal paper :
plz try to solve them urself by trying on comp.
1. const int MAX=10;
main()
{enum a {a,b,MAX};
print MAX;
}
2. enum object is a const which can only be assigned a value at
initialization or a variable which can be assigned any value in
the
middle of
the program?
3. void *p;
what operation cannot be performed on p?
ans : arithmetic operation unless it is properly typecasted
4. char **p="Hello";
print p,*p,**p
5. main()
{char str[]="Geneius";
print (str);
}
print(char *s)
{if(*s)
print(++s);
printf("%c",*s);
}
6. what does the function fcloseall() does ?
7. main()
{printf("Genius %d",fun(123));
}
fun(int n)
{return (printf("%d",n));
}
8. difference between definition and declaration.

PAPER 3

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, so that 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.




PAPER 4

1. It contains 30 Questions of SQL + PL/SQL and the TIME allocated
is 30 minutes
STRICTLY!

2. After test (15 Mins.) a Oracle guy declared test results by announcing the full name of candidates and apologising to others. Very Polite.

3. Then another test for Programming is there.

4. After this they have to go for the round of Interviews.I remembered some questions from the Test Paper:
(I wish this will help others in their preparations)

(THESE QUESTIONS ARE IN RANDOM ORDER)

Q. DELETE FROM TABLE TempV WHERE ROWID IN
(SELECT ROWID FROM TempV WHERE ROWID IN (
((SELECT MIN(ROWID) FROM TempV
WHERE ... COUNT(*) > 1)))
UNION
(SELECT ROWID FROM TempV WHERE ROWID IN (
((SELECT MIN(ROWID) FROM TempV
WHERE ... COUNT(*) > 1)));

Q. When there is a failure in fetching the rows from a cursor...
A. %ISOPEN
B. %NOTFOUND
C. %FOUND
D. %ROWCOUNT

Q. SELECT ,ORACLE, FROM DUAL WHERE NULL = NULL;
A. ORACLE
B. NULL
C. ERROR OUT
D. NO ROWS SELECTED

Q. There is a question of Package body and Package Specification, they have provided the code for that describing the scenario of movie_tickets_sold and asked the programmer to insert a block of code...., where that code block to be inserted? In Package body? or in Package Specification?

Q. Which of the following operator is not used in Outer Join?
a. =
b. !=
c. AND
d. OR

Q. PL/SQL uses which of the following
a. Early Binding

CREATE OR REPLACE TRIGGER delete_row
ON DELETE did not remember the complete code for this ...
....

if table contains 100 rows and it is truncated, how many rows get
updated
a. 0
b. 1
c. 100
d. No rows updated
