Hi Friends
This is Aakanksha gaur student of cdac tvm. I gave L & T IES written exam on 29th Aug 13.
The written paper consisted of 3 sections:
1. Aptitude.
2. Electronics.
3. C.
APTITUDE :
For this section we got 65 mins . It again comprises of 4 sections :
i) Quantitative apti - having 15 ques and they were damn easy.
ii) English - having 20 simple ques. Like fill up, error detecting and comprehension.
iii) Reasoning - having 15 ques. Like series, cube (almost fully pictorial reasoning).
iv) Mechanical - having 15 basic ques of engg first year physics (its mandatory for everyone ).
All I can say is it was pretty easy. and R.S.aggarwal is best for this. And there was sectional cutoff so every section was mandatory.
ELECTRONICS :
For this we got 40 mins.
As I am from electronics background I got the exam paper on electronics. if a person is from CS/IT background they will get computer paper .
It was having 40 objective type questions, which includes basic analog electronics, digital electronics and basic questions on signals and system( like lti, causal signal etc) and all were very easy so it took very less time.
C :
For this we got 20 mins for 20 output finding question. They were also not that tough.
They declared its result after one hour. and almost 60 students out of 200 were shortlisted for further round i.e, GD. And fortunately I also was shortlisted for that.
Then they arrange GD in four groups of 15 student each. from which they shortlist 28 students for technical round .
For my GD group topic was NEED OF GOOD LEADER IN INDIA and they shortlist only 6 students including me out of 15.
Then they call the shortlisted students for technical and HR round on 10th Sept, 2013.
For every student technical round was of 30 to 40 mins.
Few of technical round questions are :
1. Describe your project?
2. What is const?
3. What is volatile?
4. Diff b/w const and volatile?
5. Preprocessor directives?
6. Why and when we are using #error ?
7. What is thread?
8. What is process?
9. Scheduling techniques in os?
10. Diff b/w os and rtos?
11. Diff b/w mutex and semaphore?
12. When we r using #define?
13. Function pointer?
14. Memory leak?
15. Debugging techniques in os?
16. Isr?
17. Kernel mode?
18. Some ques related data structure?
19. File operation?
20. Practical use of volatile?
21. Adc setup?
22. Dynamic memory allocation?
23. Malloc syntax and ques?
They asked to write a programs also to every student. Few of them are:
1. Swap two no without using temp variable?
2. Add two no without using + operator?
3. Subtract two no without using " operator?
4. Prog to implement function pointer?
5. Check whether bit is set or not ?
6. Segregates a no e.g, 245 wil give 2 then 4 then 5?
All I can say is be précised with your answer and don't try to bluff them. and your project description will take your technical interview in particular direction. I mean if your project is based upon microcontroller they will start asking u ques related to that.
(if your project is based on microcontroller, be thorough with the concepts of microcontroller and with basic programming also like setting and clearing a bit in c).
After some time they declared my result and I was got shortlisted for HR round.
My HR was of 25 mins. HR was contradicting on all my answers and so all you need is to be patient.
Few HR ques which he asked me are:
1. Tell me about yourself?
2. New technologies in electronics field?
3. Strength?
4. What u have learnt by yourself?
5. About family?
And don't take HR round lightly. Its not that easy. HR person will check you from every aspect i.e, your patience level(like by asking same ques many time ), your comm. Skills , How you react on particular thing etc.
But the process was not completed in a single day so for remaining students they conduct the interview on 20th sept, 2013. and final result they declared on 25th sept, 2013. and fortunately I got placed in L & T IES

_________________________________________________________________________________ L&T ECC PATTERN - 09 APR 2007 - KOLKATA
Hi Friends
This is Abhishek Kar, student of B-Tech (Electrical 3rd year F.I.E.M)
On 9th April 2007 M/S L&T(ECC) had conducted a pool campus. Probably more than 15 colleges were there. And more than 700 students were there.
There was a WRITTEN TEST OF 96 QUESTIONS (Time:40+40=80min). AND IT WAS DIVIDED INTO TWO PARTS.
PART A : (40 min) 36 QUESTION FROM NON-VERBAL REASONING. Each was very easy. Any one can do it.
PART B : (40 min) 60 QUESTION FROM MECHANICS. To attempt this questions u need basic knowledge in Mechanics.
The Questions were very conceptual. There were 6 question from gear, 2 question from pascals law, 5 question from center of gravity and so on.
The Students were scheduled in 4 Batch (for aptitude test). There were almost 120 Students in the 1st batch. From which only 8 had cleared the aptitude test.
In 2 nd batch there were almost 150 students and only 13 had cleared the aptitude test. I dont know anything about the rest two batch.
I was eliminated from aptitude test. I attempt 52 questions (confidently). probably the cut off was more than that.
I would like to advise everyone that they recruit only the students who are technically very sound. So focus on your technical part. Example: If you are an Electrical Student Then try to focus on Electrical Machins, Power System, Machine designing, Basic Electrical etc)

Hi Friends
This is Aakanksha gaur student of cdac tvm. I gave L & T IES written exam on 29th Aug 13.
The written paper consisted of 3 sections:
1. Aptitude.
2. Electronics.
3. C.
APTITUDE :
For this section we got 65 mins . It again comprises of 4 sections :
i) Quantitative apti - having 15 ques and they were damn easy.
ii) English - having 20 simple ques. Like fill up, error detecting and comprehension.
iii) Reasoning - having 15 ques. Like series, cube (almost fully pictorial reasoning).
iv) Mechanical - having 15 basic ques of engg first year physics (its mandatory for everyone ).
All I can say is it was pretty easy. and R.S.aggarwal is best for this. And there was sectional cutoff so every section was mandatory.
ELECTRONICS :
For this we got 40 mins.
As I am from electronics background I got the exam paper on electronics. if a person is from CS/IT background they will get computer paper .
It was having 40 objective type questions, which includes basic analog electronics, digital electronics and basic questions on signals and system( like lti, causal signal etc) and all were very easy so it took very less time.
C :
For this we got 20 mins for 20 output finding question. They were also not that tough.
They declared its result after one hour. and almost 60 students out of 200 were shortlisted for further round i.e, GD. And fortunately I also was shortlisted for that.
Then they arrange GD in four groups of 15 student each. from which they shortlist 28 students for technical round .
For my GD group topic was NEED OF GOOD LEADER IN INDIA and they shortlist only 6 students including me out of 15.
Then they call the shortlisted students for technical and HR round on 10th Sept, 2013.
For every student technical round was of 30 to 40 mins.
Few of technical round questions are :
1. Describe your project?
2. What is const?
3. What is volatile?
4. Diff b/w const and volatile?
5. Preprocessor directives?
6. Why and when we are using #error ?
7. What is thread?
8. What is process?
9. Scheduling techniques in os?
10. Diff b/w os and rtos?
11. Diff b/w mutex and semaphore?
12. When we r using #define?
13. Function pointer?
14. Memory leak?
15. Debugging techniques in os?
16. Isr?
17. Kernel mode?
18. Some ques related data structure?
19. File operation?
20. Practical use of volatile?
21. Adc setup?
22. Dynamic memory allocation?
23. Malloc syntax and ques?
They asked to write a programs also to every student. Few of them are:
1. Swap two no without using temp variable?
2. Add two no without using + operator?
3. Subtract two no without using " operator?
4. Prog to implement function pointer?
5. Check whether bit is set or not ?
6. Segregates a no e.g, 245 wil give 2 then 4 then 5?
All I can say is be précised with your answer and don't try to bluff them. and your project description will take your technical interview in particular direction. I mean if your project is based upon microcontroller they will start asking u ques related to that.
(if your project is based on microcontroller, be thorough with the concepts of microcontroller and with basic programming also like setting and clearing a bit in c).
After some time they declared my result and I was got shortlisted for HR round.
My HR was of 25 mins. HR was contradicting on all my answers and so all you need is to be patient.
Few HR ques which he asked me are:
1. Tell me about yourself?
2. New technologies in electronics field?
3. Strength?
4. What u have learnt by yourself?
5. About family?
And don't take HR round lightly. Its not that easy. HR person will check you from every aspect i.e, your patience level(like by asking same ques many time ), your comm. Skills , How you react on particular thing etc.
But the process was not completed in a single day so for remaining students they conduct the interview on 20th sept, 2013. and final result they declared on 25th sept, 2013. and fortunately I got placed in L & T IES

_________________________________________________________________________________ L&T ECC PATTERN - 09 APR 2007 - KOLKATA
Hi Friends
This is Abhishek Kar, student of B-Tech (Electrical 3rd year F.I.E.M)
On 9th April 2007 M/S L&T(ECC) had conducted a pool campus. Probably more than 15 colleges were there. And more than 700 students were there.
There was a WRITTEN TEST OF 96 QUESTIONS (Time:40+40=80min). AND IT WAS DIVIDED INTO TWO PARTS.
PART A : (40 min) 36 QUESTION FROM NON-VERBAL REASONING. Each was very easy. Any one can do it.
PART B : (40 min) 60 QUESTION FROM MECHANICS. To attempt this questions u need basic knowledge in Mechanics.
The Questions were very conceptual. There were 6 question from gear, 2 question from pascals law, 5 question from center of gravity and so on.
The Students were scheduled in 4 Batch (for aptitude test). There were almost 120 Students in the 1st batch. From which only 8 had cleared the aptitude test.
In 2 nd batch there were almost 150 students and only 13 had cleared the aptitude test. I dont know anything about the rest two batch.
I was eliminated from aptitude test. I attempt 52 questions (confidently). probably the cut off was more than that.
I would like to advise everyone that they recruit only the students who are technically very sound. So focus on your technical part. Example: If you are an Electrical Student Then try to focus on Electrical Machins, Power System, Machine designing, Basic Electrical etc)
