I think everybody's very keen to know about the GD-PI and written test.
My bros!! this is straight from the horses mouth.
It was feb 21st 2006,warm weather,the trains were on time.

The time given to me was 2pm.The whole process takes about 3hrs only,and i tell u SIES is very puntual and systematic.
As raheel said,the written test is very easy if u had studied for CET,its so easy that u'll come out smiling,but as soon as u realise that everyones smiling..u'll stop smiling

,so the point is- its VERY easy..

My personal suggestion would b gear up up for the GD-PI.
TIPS -
1.Read newspaper daily,especially the financial news and the world news.
2.if u have an experience, review what u had done in ur job projects,dont exaggerate on that as sometimes u generate questions for the interviewer through ur extra blabber.
3.lastly make sure u r confident about what u have written in ur forms eg.hobbies,projects,activities etc,review all that bfore the interview.
I had 2 gds and 1 PI,the process may slightly modify this year but not much.
A group of 10/12 students would b given a mentor(i may b one of them

& he/she will guide u through the process.
The process is smooth!!..
ALL THE BEST!..will meet u in feb.
Regards.
