I am Sakshi Kohli from JMIT, Radaur (3rd yr Instrumentation & Control). TCS visited our campus on 28-29 feb 2008. I wud like 2 share my experience wid u. There were around 450 students out of which 57 were selected. 290 had cleared the written test. by God's grace I was one them. There are four rounds :
1. WRITTEN TEST-
This was an online test 90 questions, 90 minutes. The test comprised of three sections in the online test you have to go in serial order for three sections. Within the section you may revert back to any question within that section. Time is limited for each section.
SECTION A - Verbal section 32 questions,20 minutes. 10 antonyms 10 synonyms, 1 sentence completion, 1 read comprehension. it is very difficult to manage time in this section. Prepare GRE barrons high frequency word list (330 words) for this section from 12th addition. Also words given in five model test papers you may not be able to score much in this section.

Assuming no error during transmission, write a formula to calculate the time taken in seconds to successfully complete the transfer of a file of size N kilobytes.
(ans:(n/1000)*(n/10)*10+(n/100). May be dis is ans u can mug it up.i cud not write dis ans dere).

Sol) log 0.317=0.3332 and log 0.318=0.3364, then
log 0.319=log0.318+(log(0.318-0.317)) = 0.3396. (a question matching to this. not same dis is just an idea).

Q-41 Question on venn diagram wid 3 sub-parts.like English, Bengali, Hindi...
Q-42 question on data interpretation (bar graph) 3 sub-parts.simple
This section is very simple if u hv prepared previous papers properly. These are availiable on dis site. Almost all questions are 4m previous papers. The figures may be changed. Do data interpretation 4m r.s.aggarwal (quant), venn diagrams 4m r.s.aggarwal (verbal, non-verbal).
SECTION C - CRITICAL REASONING
Prepare all 5 model test papers 4m GRE-Barrons (strictly 12th edition) critical reasoning part. Questions are cut, copy, paste 4m dere. prepare dis part very well. its MUST.
NOTE: WITHOUT GRE-BARRONS (12th EDITION) ITS VERY VERY DIFFICULT TO CLEAR THE WRITTEN TEST.
2. TECHNICAL (T.R.): To I&C students its my suggestion prepare atleast 1 subject really well.I prepared micro processors.They asked me to explain 8085 block diagram and also abt programming while performing practicals. Prepare C and C++ as per ur resume.they asked me differences between C and C++. Also I was asked to write a program on factorial.
3. H.R.: Here situations were given to me like on customer satisfaction. Basically they are checking ur confidence. why TCS ? why TCS should hire you? Strengths, weakness.
1. Prepare ur resume wid utmost care.
2. Refer to papers on this site. These are really very beneficial.
3. Greet them well when u go for inter-view.
4. Keep smiling.
5. Eye-contact is very important.
6. Do not argue. Remember they know much more than u do. Be polite.
7. They will be very nice and will try keep u calm.
8. Do not give excuses. just BE CONFIDENT when u answer. Confidence is most important. Also be careful wid ur mobile phones. TCS looks 4 discipline.
