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.

SECTION B - Quantitative aptitude

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.

FEW POINTS:
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.
