L&T INFOTECH PATTERN & INTERVIEW - 23 DEC 2007

Hi Friends

I am Karthik, I have attended  L&T infotech on 23rd December 2007 at Nalanda institute of technology.

The  process consists of four rounds
1. Written test
2. GD or JAM round
3. Technical interview
4. HR round

The written test consists of 90 questions to be solved in 90 minutes,
The test consists of quantitative aptitude, verbal and non verbal reasoning and English,

Important topics:
• Pipes & Cisterns.
• Boats & Streams.
• Alligation & Mixture.
• Simple Interest.
• Profit & Loss.
• Probability.
• Problems On Ages.
• Time & work.
• Time & Distance.
• Discount.
• Problems On Numbers.
• Average.
• Plz refer Bar, Line, Pie Graphs because 6 ques will be based on any one of the graphs.

The only thing you have to do to clear the cutoff for written test is to prepare the worked out examples of RS Agarwal quantitative aptitude

Section 2 (Logical Resonning): Refer R.S.Aggarwal Verbal & Non Reasoning book.

The chapters are
• Blood Relations.
• Puzzle Test.
• Coding-Decoding.
• Statement Assumptions.
• Statement Conclusions.
• Conclusions from Passages.
• Logical Venn Diagrams.
• Arithmetic Reasoning.

This section is time consuming, so keep time management. First work out Arithmetic Reasoning.

Section 3 (Verbal Ques):
• Synonyms (5 ques).
• Antonyms (5 ques).
• Correct the Sentence.
• Analogy.
• Ques from long passage(its very easy).

Note: There is sectional cutoff.. I think its 22 out of 30..Totally app. 800 attended only abt 74 cleared written test,
There is no negative marking, time management is important

The second round was a JAM round, where we have have speak on the topic our choice for two minutes, until they ask you to stop, keep on talking, but see to it that it is not memorized,

Out of 74 they have shortlisted 37 for the technical round, In the technical round, as I am fron ece, the interviewer mainly concentration on electronics subjects like EDC, OPAMPS, Digital electronics. For CSE. and MCA, they are asking on C, Data structers (linked lists), OS, Computer networks
