cts interview

==========================udddalakbanerjee(ubj)

###this is based on real life incident..and each of the dialogues are real ones that took place between ubj and the interviewer from CTS.


THE INTERVIEW WAS TAKING PLACE AFTER 7:30 AT NIGHT .My panel no was 6 .There were about 158 people shortlisted after the written test.Interview was taking place in alphabetical order so my name came at 19th in my panel and it was really late and I was growing very restless.Anyways finally the call to go in came.

INTERVIEWER,”COME IN ..”

UBJ,”GOOD AFTERNOON SIR..”

INTERVIEWER,”TAKE YOUR SEAT..”

UBJ,”SIR THIS IS A BOOK THAT I HAVE WRITTEN ..THIS CONTAINS POEMS AND SHORTSTORIES WHICH ARE TO BE PUBLISHED SOON IN A LEADING MAGAZINE IN THE WORLD.”
INTERVIEWER,”HMM..what does this J MEAN?”

UBJ,”SORRY SIR COULD NOT GET U .”

INTERVIEWER,”U HAVE WRITTEN UBJ ..YOUR NAME IS UDDALAK BANERJEE SO IT UB ..SO WHAT IS THIS J FOR?”

UBJ,”JEN X”

INTERVIEWER,”SO THEN..TELL ME SOMETHING ABOUT YOURSELF”

UBJ,”I AM A ROCKING HONEST AND SIMPLE PERSON WHO MAKES LIFE WORTH LIVING .i WRITE BECAUSE IT IS MY HOBBY AND FIND FULFILLMENT IN IT.I AM VERY DIRECT IN MY APPROACH AND I LOVE TO PAINT TOO.MY MOM AND DAD ARE IN BANKS AND I BEING THEIR ONLY SON AHD DEDICATED MY LIFE FOR COMPUTER ENGG AND WRITING.I HAVE A LOT OF FRIENDS AND FANS BOTH AND I LOVE THEM VERY MUCH.”

INTERVIEWER,”WHICH LANGUAGES DO YOU KNOW?”

UBJ,” WELL I know languages C,C++,VB.Net,Java,shell scripting etc..but I know them all in elementary levels only ..Actually if I say that I know these languages…it means that I know them to the fullest which again Is perhaps impossible because the ambit of these languages is very huge and to know every function is redundant for any one may be.It is impossible to learn any language to the fullest.”

INTERVIEWER,”DEFINE A STRUCTURE AND WRITE A CODE IN C FOR STRUCTURE”

UBJ,”Structure is a memory block that is used to store data of similar interreleated types.Code for structure would be
Struct C
{
Int I ;
Char c;
Float f;
}
To call:
From main :
Struct C a,b,c …and so on.;
A,b,c are structures of the type C
INTERVIEWER ,”TELL ME THE MAX APPLICATION U KNOW OF C?”

Ubj,”rockets can be launched using C .We can make functions and modules for the same.”

INTERVIEWER,”ILLUSTRATE”

UBJ,”the entire rocket launch sequence is based on the primitive equation p=mv and we need to go on differentiating this equation .but yes in C WE DON’T have any such differentiation function so we have to create functions separately to calculate float values of minor differences with a loop of time to minitor minor changes.Now then we have to break the whole thing into modules.There would be modules for propeller speed,module to calculate air drag and backward thrust exerted by air and also speed variation factor based on climate and then there would be distance calculation function that would calculate distance from earth.Apart from all this there would be a module on air density and temperature calculation which would take data from the sensors fitted on the body of the rocket and this function will be called ever pico second.With C being a middle level language all this possible because it interacts with hardware.


Interviewer,”So then tell me about hobbies now..if I give u a choice between programming and writing which one will u choose ?”

UBJ,”WRITING and not programming”

Interviewer,”why ?”

UBJ,”BECAUSE I am popular with this and I believe that I write well and now that I am beginning to get to people whom I have never met or seen I don’t want to leave this medium.

Interviewer ,”but !!ok leave it”(looks through the book)

Interviewer,”you write well..but will this give you enough living?”

UBJ,”I DON’T KNOW BUT YES ONE THING IS FOR SURE I LOVE IT.”

Interviewer,”what is ubj inventions?tell me something on this”

UBJ,”when I was in school I wanted to calculate rather extrapolate values of pi from mechanics using different values of constants and I tried hard and found various values and I have enumareted the values and methods used in these blogs.I have done some papers on AI too so that is again a part of ubj inventions.”

Interviewer,”ok but now tell me inventions or writing which will u prefer”

UBJ,”writing sir..it is part of documentation process .I love it.”

Interviewer,”ok then.It had been a pleasure meeting you.” (flips through the pages of the book)

Interviewer,”nice work someday u may be a great writer.”

UBj,”thank you sir”

Interviewer,”next”

THIS WILL PROVIDE A VARIETY IN TERMS OF PRACTICE.THE QUESTION PAPERS FROM 2000-2007 WAS HARD TO GET BUT FINALLY PROCURED THEM.AND NOW I AM UPLOADING THEM...I HOPE THIS WILL PROVIDE ENOUGH OF PRACTICE AND NEGATE THE NEED FOR ANY FURTHER TUTORIALS.


CS-2007

GATE 2010 QUESTION PAPER

THIS TIME THERE WAS APTI..AND THOSE WHO DID ATTEMPT A LOT ALEAST AROUND 60 MARKS ATLEAST DID WELL UNLIKE THAT IN 2009 WHEN THE QUESTION COMPARATIVELY WAS TOUGHER .

CS-GATE-2010

STATISTICS OF GATE

TOTAL NO OF STUDENTS THAT TOOK GATE IN COMPUTER SCIENCE AND ENGG WAS 107000 (1 LAKH 1O THOUSAND APPROX)

UNLIKE OTHER BRANCHES THE TOTAL NUMBER OF STUDENTS APPEARING GATE IN COMPUTERSCIENCE IS DOUBLE AND MORE BECAUSE COMPUTERSCIENCE AND IT ARE TWO FULL FLEDGED BRANCHES WHO TAKE GATE UNDER THE SAME BANNER.iT AND CS ARE ALSO TWO BRANCHES WHICH ARE TAUGHT IN ALMOST ALL ENGINEERING COLLEGES OF INDIA .AT PRESENT THE TOTAL NUMBER OF ENGINEERING COLLEGES IN INDIA IS ABOUT 6700 AND TOTAL NUMBER OF MBA COLLEGES STAND 3300 APPROX.AND THE NUMBER OF COLLEGES IS INCREASING AT A HEALTHY RATE EACH YEAR.

FOR TECHNICAL TRAINING THE PLACES LIKE BANGALORE AND HYDRABAD ARE MOST SUITED BECAUSE OF THE MYRIAD NUMBER OF COLLEGES THAT CROP UP FROM ALL CORNERS OF HYDRABAD AND BANGALORE AND PRESENCE OF HUGE NUMBER OF TRAINING INSTITUTES IN HYDRABAD AND BANGALORE.INCASE ANY JUNIOR READING THIS POST PLEASE OPT FOR YOUR SUMMER TRAINING IN HYDRABAD OR BANGALORE BECAUSE THEY ARE THE PLACES WHICH ARE A HUB OF TECHNOLOGY AND YOU CAN REALLY REALLY LEARN HERE BECAUSE OF THE LARGE NUMBER OF COACHING INSTITUTE WHICH ABOUND HERE SOMEWHAT LIKE KOTA WHERE PEOPLE THRONG FOR IIT JEE PREPARATION.

SO PLEASE MAKE SMALL GROUPS AMOUNG YOURSELVES AND DONT FEEL SHY OR LAZY TO GO THERE FOR TRAINING .IT WOULD PROVE REALLY BENEFICIAL TO YOU IN THE LONG RUN.

IT IS A REAL LIFE EXPERIENCE BASED COMMENTRY MODE INTERVIEW.THIS SHOULD HELP ALL JUNIORS AND VIEWERS WHO ARE PREPARING FOR BIRLASOFT OR EQUIVALENT COMPLETELY TECHNICAL LOW RECRUITING CS COMPANIES.
