Hi friends, I am Anandhan. K from I.F.E.T COLLEGE OF Engineering,VILLPURAM. Recently I had appeared for off-campus interview conducted by VIT PLACEMENT PROGRAMME on 28 & 29th JAN2011 at VIT, VELLORE .
Aptitude Technical Group Discussion Technical HR Personal Interview
WRITTEN TEST (MAJOR ELIMINATION TAKES PLACE, SO, CONCENTRATE MUCH ON THIS)

I. APTITUDE
In this round, they asked 40 questions in 40 minutes which includes

Two from Venn diagram, (easy)
One from probability,
3*3 Sudoku like below, (very easy)
8 2
9

You have to fill the numbers from 1-9 in the boxes, such that it should  have 15 from top to bottom and across the diagonal, then you would have the box  as like the one below:
8 2 5
1 4 7
6 9 3

From this you might have questions like, summing up the numbers which are  right and left to the number 2. For us, three questions were asked from this:
Some four questions were asked from the four different passages. One problem based on age. (easy) Three questions based on Speed and Distance.   One from permutation Percentage ( easy ) Few questions based on functions. (very easy one)

2. GROUP DISCUSSION

CSC is mainly looking in your communication and how well you are confident at.
These guys are giving chance to everyone in putting their own points. i.e., they  are conducting it in orderly fashion. She gave us: Should sex education be  included in academic of school children. I was the first to start the GD, so, I  went with the topic and No time was given to prepare. Results were immediately  announced. In my batch, only one got eliminated.
So guys, be confident while  putting your points. GUYS dont initiate take time get some valid point then talk (100% fluency expect)
Topic:
Indian education system,valentans day,BPO services,About Bank etc....
but i got eliminated at this round they taken 10:1 ratio.. its not my Day...
but my friends are attend next round i had some remaining question forHR round....

3. TECHNICAL HR
Initially the HR was started with my project, I explained my project  entirely. And he raised few questions from that. I answered for all those. So,  you must have thorough knowledge of your project you had done.

Besides, he raised questions like difference between array and Linked list then  Stack, Queue from Data Structures, DBMS, and Operator Overloading, paging  concept from Operating System, few concepts from Mobile Computing and some more.  It took some 25-30 minutes for me.
Depending on the panel, you will get questions. You brush up all the concepts  from Data Structure, DBMS, Operating System and Programming Languages.
If you are belonging to ECE, concentrate much on Microprocessor. (This info was  given by my friend).
You just give your answers if you are sure, otherwise, you say, sorry mam/sir,  at present, I could not recollect. Do not try to give related or fake answers.
