HCL Technologies General - Interview Paper - 6

HCL TECHNOLOGIES PAPER ON 1st MARCH This is Abhisek from MCKV Institute of Engineering, I am going to share my experience about the HCL Technologies Campusing procedure which took place in our college on 1st & 2nd March 2007. It took 2 days for the whole process to end. The who process is based on ..... 1. PPT 2. Aptitude = 35 Apti questions( 1 hr ) + 20 Technical questions ( 15 mins ) 3. Technical Interview 4. HR Interview The reporting time was 9:30am ........ but the flight was late ........ so the mam along with two sirs came after a short delay ....... at abut 10-30 ....... and the PPT tated around 11. there was a nice video at first, I recognized that was a "HCL Anthem" ( http://www.hcl.in/anthem.asp )video and a bit modified from HCL s website. them mam explained the facts of HCL and 18 month bond, statistics etc. Try to listen the PPT carefully ....... though its boring, that comes handy in HR. Mam asked me only abut HCL in HR. The Aptitude part was mainly composed of ... 1. Some Puzzles( From RS Agarwal,s Non-verbal and Sakuntala Devi ) 2. Some DI problems( very easy if u focus ) 3. Some CAT standard passages ( i.e. 2 questions for 1 page long passages ) So My suggestion will be first attempt the DI,then eng, then take rest of time to solve puzzles . The paper was a bit tough ...... but DI and English was much easy though. BEWARE, THEY SAY THERE MAY BE NEGATIVE MARKING, BUT THERE ISNT ...... ITS ONLY MAY BE, SO TRY TO ATTEMPT ALL QUESTIONS The Technical part was a bit easy ...... mainly composed of C,C++,OS and mainly pointer based problems. ECE guys may hav some problems with that. 127 given d exam ....... and 86 cleared d aptitude.

HCL Technologies Whole Testpaper Paper - 4

We wer called by the hcl technologies for recuritment in their office only.
The written papre consisted of 2 sections 1-apptitude 2-branch specific.
Apti paper was damn easy.thr wer 60 questions to b done in 55 minutes.no special practice reqired 4 ths.
Kep ur eyes open mind alert and chck on the time.thts it
Some of the questions wer:-
1 if a+b means a is son of b and a-b means a is daughter of b and a*b means a is wife of b thn
p+q-r*t.wat is the relation between p&t?
2 english Rc.very easy one.4 passeges having 10 questions.
3 flow chart questions.thr wer 6 questions on flow chart.
4 pie chart question.Tht is the di section.u dnt even need to use ur pencil 4 solvin it
5 some technical questions like how s virtual memory implemnted-demand paging
1) question was on article whose option wer a,a & a,the &the,a & the,the.the answer was the,the
two meaning question wer thr whose answer wer mass killing and formal statement.
Analogy question wer thr like:-
(analogy:bmbkpfz) and 4 option wer given the relations 4 analogies wer quite simple as u can see.
Number series wer given like 122433566412864278 and question wer asked like hw many consecutive even number pairs
Are thr whose sum is a single digit ie >= 9;
All the question wer easy.jst keep the chk on the time

The second test was branch specific.each 4 computer, it and of vlsi 4 electronics students if thy want to be
vlsi specialsts.
Mine was computer test.it was a little bit tricky bt surely not difficult.
Thr wer 25 questions to b done in 20 minutes

Questions wer on c and c++ only.some of the questions i could recall wer
1-wat s the position of partition item in quick sort ansis statrtin(first)
The new malloc calloc allocate memory 4m heap
One question was on virtual base class in c++.type of error was asked bt thr was no error
One question on 2d array.
Some questions on c programs.one was insertion sort
One on binary search tree
On question on the preorder sequencing of b tree.ie 1st visit root thn visit left subtree in preorder
Again u need to keep a chk on time here also.

Thn finally thr was HR round
Same questions wer asked 4m each student and those wer vry vry general.
The questions wer 1-tell about urself 2-about family 3-why hcl? 4-academics trend i.e if ur % is decreasing thn why is it so
and if its increasing thn will u b able keep it like tht?

It dint last 4 mre thn 10 minutes.

2)Tell me about your projects done so far
3)What s a pointer and write a program to print the address of that variable.
4)How to access a pointer using structure and write a program using that
5)What s the difference between structure and union
6)Write a program using union
7)What are the advantages of pointer
8)Whats a static variable
9)What s a micro controller and the difference between microprocessor and microcontroller

10)Tell me the major advantages of microcontroller compared to microprocessor

HR Interview: female HR came to our panel.. she asked the questions so fastly and didnt wait to answer the questions fully. .I didnt expect that she ll ask technical questions in HR interview.. so BE READY FOR ANYTHING

She gave a c program and asked the output, then asked whats a pointer
1)What s ur aspiration? 2) Why HCL and wat do u know about HCL? 3) About family background...
