l & t infotech 1. a( [ b ( [a^ c]] where '(' and '^' are symbols related to set and '^' is not exact symbol , it is curved not conical(due to limitation of key board ), represents"union" a. has no sense b.it is associative as well as commutative 2.2's complement of given binary number 3. octal equivalent of a binary number 4.given -ac + ab + bc = a. ac -b. bc+ac 5. question related to linked list given a program coding in c++ and asked what it is doing.class definition not given choices were a. deleting a node b. adding a node at head c. adding a nde at end i think it is adding a node at the head of the node. note:you must go through linked list verywell both class definition and program to adding the node ,deleting the node , initialising the linked list etc.. 6.some questions related to data structures like traversing through queue tree etc. 7.evaluate given polish prefix expression ( i am not remembering the expression) 8. list| sort | more a. lists the files after sorting and diplay "more" b. list or sort the file and ask for any more files ( i do remember only these two choises ) 9. copy queue/sort txt.axb queue/ajith cd queue/ajith ren txt*.axb txt*.ayb del *.ayb dir what are the files listed? choices a. only '.' and '..' b. all files starting txt c. no files listed 10. 1 simple question from cobol a) what is reverse engineering. b) octal of some binary number(comes to 165 in decimal after conversion). c) a cobol prog with an integer array(i guess coz i did not have cobol in my syllabus). d) a problem on depth first search(very simple). e) question on grammar's frm theory of computer science. f) something like select the correct option when

a subset of (b subset of ( a intersection b) if b is completely contained by a. g) a question on memory(quite simple). h) a couyple of questions on c(one on pointers). these r all i can remember. part 1:-> ekt(engg knowledge test) [technical] -concentrate more on datastructure like sorting methods thier timings,simple unix command like touch, simple c programs on strings.. the ekt test consisted of 40 objective type questions which we had to solve in 40 minutes.a majority of the questions were based on mathematical logic such as "reflexivity", "tautology","p^q->r" etc.the technical paper usually contains questions related to data structures, operating systems,c,c++,unix and many more comp.sci dept.the technical paper usually contains questions related to data structures,operating systems,c,c++,unix and many more comp.sci dept.it also contains questions from cobol, lisp, c, discrete structures, databases etc.there is a question on finding the hamming code. some questions : 1) what is a smith chart used for 2) how is impedance matching done and why do we need it (basically can talk about ideal power supply needing a low internal resistance and high load to function properly. so one stage of transistor amplifier has to have low o/p resistance and high i/p resistance for next stage- do look up all basic electronics) ( also about sinking high currents without damage) 3) name all flipflops u know and working esp. master slave. 4) c progaming - program to find how many 1's are present in an integer variable using bitwise operators. something about dynamic allocation, static functions, macros 5) c++ virtual functions 6) what types of control r there 7) qpsk ----------------------------------------------------------------------------------------------------------------------1. what is an inode in unix? 2. small program in pascal to add a node to a linked list. (you have to tell what the program does) 3. c strcmp program (you have to tell what the program does) 4. set of dos commands testing basic familiarity with dir, ren *.t?t, cd etc. 5. what is the order of binary search? 6. what is the order of strassens matrix multiplication? 7. you have to maintain the sorted order of integers and insert integers . which data structure would you use? (tree, list, queue, array?) 8. there are two lists of integers to be merged. which method would you not use? 9. in an online database system when is data written to disk? (on pressing enter, when commit or update is encountered, at end of data, all of the above) (was clueless! ) 10. small prolog function which prints 2345true. you need to tell output. 11. convert this binary into octal. 010 100 101 12. lisp program given. what does it do? (gcd, lcm, multiplies mxn?) 13. what is paging?

14. what is segmentation? 15. 2/3 questions on equivalence class, associative and commutative properties. 16. question on poset. 17. one figure given, give regular expression for it (very basic) ------------------------------------------------------------------------------------------------------------------------part 2:-> the second part is of 30 minutes and covers various (imho irrelevant) topics. some more questions. remember all are multiple choice questions with either 4 or 5 options so you have at least a 20-25% chance of being right even if you are clueless. no negative marking. determining the next figure 3x3 matrix.they willnot give any example problems.u have to find ur way. prepare well in that go through rs agarval verbal and non verbal reasoining and in reasoning there was only one kind of questions. that is, find the next match among a group of figures. figure matrices: in figure matrices, 9 figures are arranged in the form of a matrix with one figure missing and the candidate is required to analyse the the complete sets, find out the common rule and then on its basis, find the missing figure in the incomplete set.it consisted of 36 questions on figure matrices which we had to solve in 30 minutes. the questions were easy but generally you don't get time to solve each and every problem. t was very easy with 36 questions (40 minutes)of advanced progressive matrices there was negative marking also.all questions were similar to the questions given in rs agarwal verbal & non verbal reasoning .first 27 questions were very eas.last 9 were bit tuff .8 figures will be given and we should find similar 9th figure.it was very easy.gave the results just after half an hour.called for tech interview. just prepare figure matrix in rs agarwal verbal & non verbal reasoning more than enough for written test then after a long waiting there was tech interview for more than 40 minutes.two persons were there per each panel.they asked me in which subjects r u confident i said it oop\'s.they asked based upon oop\'s concepts basics. polymorphism virtual functions what is the difference between array and linked lists. linked lists,stack and queues(and there structure declaration) and recursion , they asked qns on computer networks also osi model and tcp/ip which is the better option some basics functions of each layer. at last after some general qns they said.all the best for the next round. after waiting for 3 hours there was a hr interview it was cool .with as usual general qns. the person said they will informing within 1 week. hi ,

the written test pattern of l&t infotech has been put up here already so i am just going to mention my interview details. my interview was in blore. duration about an hour. basically the questions are from every single subject you would have covered in your engineering. there were 2 people in the panel that interviewed me, one person was focussing more on software concepts, the other asked me about communication, microwave, control systems. some of the questions were like: 1) what is a smith chart used for 2) how is impedance matching done and why do we need it (basically can talk about ideal power supply needing a low internal resistance and high load to function properly. so one stage of transistor amplifier has to have low o/p resistance and high i/p resistance for next stage- do look up all basic electronics) ( also about sinking high currents without damage) 3) name all flipflops u know and working esp. master slave. 4) c progaming - program to find how many 1's are present in an integer variable using bitwise operators. something about dynamic allocation, static functions, macros 5) c++ virtual functions 6) what types of control r there 7) qpsk 8) though i did mention that i was most comfortable with digital systems, microprocessors, i was asked only one or 2 questions on this topic like what is program counter, stack operation, etc. 9) a lot about final year project. 10) all electives, and subjects mentioned in cv. 11) cv as in most companies, is inspected very carefully during interview. so be careful what u put there lest they ask u something u are not prepared for. i am sorry i cant remember any other questions but i hope this gives u atleast a rough idea about what subjects to cover. also ur written test marks are very important. the order in which they call the people also indicates where u stand so try and compensate by doing well in interview if ur name is towards the end of the list. u would improve ur chances i believe. hr interview was only for around 10 minutes, they call if u have cleared tech interview. they asked about what i had been doing for the past 6 months, my plans, how l&t would help me. why l&t etc. the proceedure in mumbai however was totally different i think. they had gd, and hr interview i hear was gruelling. ur gk(number of states in our country, number of lady cms in india,etc.) is tested thoroughly. the form that u are given to fill before the interview, is reqiured to be filled in your neatest handwriting (i really think this is imp.) and do take a lot of trouble to write things that would put u in good light. lots of luck to all u chennai people trying for l&t infotech. though they have a 2 year bond, this company is really worth going for. do hope this information helps you a bit. (paper submitted by : aparna shenoy) hello

i had been to their entrance test in mumbai on nov 28 for the post of set( sofware engg trainee). since it has been almost a month i gave those exams i don't remember the questions but i remember the pattern which they had followed, there were two tests one was the ekt(engg knowledge test) and the other test was totally on figure matrices. 1. ekt(engg knowledge test) - the ekt test consisted of 40 objective type questions which we had to solve in 40 minutes. a majority of the questions were based on mathematical logic such as "reflexivity", "tautology","p^q->r" etc. then there were questions based on cobol, sql, prog in c et. there was a question on finding the hamming code. 2.figure matrices: the another test was on figure matrices, in figure matrices, 9 figures are arranged in the form of a matrix with one figure missing and the candidate is required to analyse the the complete sets, find out the common rule and then on its basis, find the missing figure in the incomplete set. it consisted of 36 questions on figure matrices which we had to solve in 30 minutes. the questions were easy but generally you don't get time to solve each and every problem. please reach early at the test venue on the day of the test. the sooner you get to write the test.

here is the test pattern for set(software engineer trainee): . the paper is in two parts in the first one there are 40 questions of visual reasoning and in second there are 50 questions from miscellaneous 30,40 topics question paper is here: part 1:-> psychometric test. easiest thing in the world. eight figures with you having to predict the ninth. just use some common sense and u r thru this test. a word of caution tho; plz. do not waste time on a question if u r not sure ,just come back later n then do it. (36questions- 40minutes.) part 2:-> engineering syllabus based technical test now this sectin is a bit tricky. warning: absolutely do not waste time on any question. u hardly get any time to think. (40 questions n 30 minutes.) some of the questions r a s follows:a) what is reverse engineering. b) octal of some binary number(comes to 165 in decimal after conversion). c) a cobol prog with an integer array(i guess coz i did not have cobol in my syllabus). d) a problem on depth first search(very simple). e) question on grammar's frm theory of computer science. f) something like select the correct option when a subset of (b subset of ( a intersection b) if b is completely contained by a. g) a question on memory(quite simple). h) a couyple of questions on c(one on pointers). these r all i can remember. next round was the gd. by the way out of the 21 ppl who attended the test with me only 9 including myself were selected.the gd was amere formality i guess. we were given the topic "do u think women make better managers?" a debatable topic , but we merely agreed with each other and no big problem with it. (paper submitted by : n.khanna) l&t infotech paper - 2003 there are 2 parts 1. technical 2. aptitude ( whole based on related

figures not mathematical questions )

aptitude: identify the unknown figure from given related figures> 3 sets of figures(shapes ) are given .each set having three figures last shape of third set will be missing and you have to identify it by checking other combinations a1 b1 c1

a2 b2 c2

a3 b3 x

find x?

given 8 number of choices. (some times x is decided by whole combinations ie, a1, a2 ,a3,b1,b2,b3,c1,c2) some combinations will be complicated .so be calm and quite when attendung the aptitude test.care must be taken to utilize the allocated time perfectly since you have only 30 minutes for 36 questions and you have to deal with some complex figures (i think in the middle part given combinations were complex ;complex means very complex). my advise is to be practise well before attending the test.since tchnical part is not hard your fate is decided by aptitude test only. technical: there are 40 questions and 4 choises for each duration : 30 minutes -----note :------------------------------------------------------------------------------------------------------------i list here some questions and some choices that i do remember, as it is. some times there may be mistakes in questions and choices.my intension is to present how the test would be. -----------------------------------------------------------------------------------------------------------------------1. a( [ b ( [a^ c]] where '(' and '^' are symbols related to set and '^' is not exact symbol , it is curved not conical(due to limitation of key board ), represents"union" a. has no sense b.it is associative as well as commutative 2.2's complement of given binary number 3. octal equivalent of a binary number 4.given -ac + ab + bc = a. ac b. bc+ac 5. question related to linked list given a program given choices were b. c.

coding in c++ and asked what it is doing.class definition not a. deleting a node adding a node at head adding a nde at end

i think it is adding a node at the head of the node. note: you must go through linked list verywell both class definition and program to adding the node ,deleting the node, initialising the linked list etc..

6.some questions related to data structures like traversing through queue tree etc. 7.evaluate given polish prefix expression

( i am not remembering the expression)

8. list| sort | more a. lists the files after sorting and diplay "more" b. list or sort the file and ask for any more files ( i do remember only these two choises ) 9.

copy queue/sort txt.axb cd queue/ajith ren txt*.axb txt*.ayb del *.ayb dir

queue/ajith

what are the files listed? choices a. only '.' and '..' b. all files starting txt c. no files listed 10. 1 simple

question from cobol
