Test was of 1 hour 30 questions. g aptitude and 30 of technical.......some questions. of g aptitude were very lengthy so don't end up in solving them.....time was less......some 15 questions. from arithmetic......and rest 15 logical, statement interpretation, arrangement, tense correction......and like that...... 

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 :

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 datastructures.

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 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.
