FLEXTRONICS PAPER – 28 MAY 2005

FLEXTRONICS PAPER – 28 MAY 2005

I gave written test of Flextronics . I want to help You, as I have not remembered the
Questions I am just giving the pattern .

There are total Seven sets of papers . The exam duration is 1hr 40 mts.

Set 1 – Verbal Ability [15Q - 15mts]
Set 2 – Analytical Ability [15Q - 20mts]
Set 3 – Mental Ability [10Q - 10mts]
Set 4 – Technical [20Q - 20 mts] (Data Structures, Operating System)
Set 5 – paper of C/C++ [20Q - 20 mts] (Our choice , U will have only 1 paper.)
Set 6 – Reading Ability. [10Q - 15mts] (They will give a passage u have to read in 10 mts.
and they will take back passage. now they will give Question paper and u have to answer in 5 mts.)
Set 7 – Written Skills [5mts](We have to write a mail in the given context.)

All The Best for all the job searching people.

FLEXTRONICS PAPER AND PATTERN

hi ppl….THIS IS FOR THOSE WHO R WAITING TO GET PLACED  FROM  COLLEGE  CAMPUS ( 6TH  SEM STUDENTS)

im pradeep doing BE (computer science), MSRIT, BANAGLORE got placed in FLEXTRONICS, few days back………….

i want to share my experience with u people…..

selection process….

1)writtn test (it was bit tough)

2) 2 rounds of technical interview

3) HR

 

WRITTEN TEST:

1. english grammer type  -> 15 questions, 10 Q r like normal grammar very easy , last 5 r passage reading types very easy ( 15 MIN TIME)

2. ANALYTICAL -> 20 questions in 20 min, questions like

     SET THEORY PROBLEMS, AND  

     one QUESTION followed by statement 1: something and statement 2: something

     options: QUESTION CAN BE ANSWERED BY USING 1ST STATEMENT or 2ND or BOTH TYPE…….

     THIS SECTION WILL BE EASY

3. GENERAL APTITUDE -> 20 questions , bit tough , time consuming, CUBE PROBLEMS  r important , i dont know any material for this , i just used my knowledge ( guessd in fact) got the right answer at last……. remaining from R.S AGARVAL

 

4. DATA STRUCTURE AND ALGORITHMS:

    this part is really screwing,

they will give some programs and asked us to choose the output…..

most of the questions were on STRUCTURES…….

few on TREES, LINKED LIST

time cosuming, so do it as quick as possible…..

 

5. C OR C++ PAPER

   i selected C paper it was easy, most of the questions were on POINTERS, since im from CSE, i felt this paper was easy

   i heard C++ was bit tough, they askd  questions on  iostreams, and inheritence…….

  ( OTHER BRANCH  PPL  WILL HAVE LOWER CUTOFF IN  4TH SECTION, FLEXTRONICS MAINLY  WANTS  E&C , TELECOM PPL, I WAS THE ONLY ONE WHO GOT SELECTED FROM CSE BRANCH)

 

2. TECHNICAL ROUND

bacically there will be 3 round , 2 tech and 1 HR

i had only 2 rounds, in between they asked some HR questions…..

ROUND 1:

      – asked abt my project, some C questions, DATA STRUCTURE questions, mainly UNION( be good in this)

      – C++ questions like POLYMORPHISM,  RUNTIME    POLY MORPHISM, INHERITENCE etc

     – DATA COMMUNICATION questions like

                      DIFF  BETWEEN IP, UDP, TCP

                      PROTOCOLS LIKE->  HTTP, SMTP etc

                      all were abt basic knowledge abt communication…..

      -  MICROPROCESSOR question like , represent -31 in binary, how will u detemine that a processor is of this much bit( ans:by its data bus capacity)

 

ROUND 2:

     this was easy

    – abt SYSTEM SOFTWARE , like basic functions of assemblers, compilers, loaders, linkers

    – implement STACK program( very easy)

thats all…………..

 

3.HR:

   for me they asked hr questions in tech rounds itself

they were….

- did u reach to any HR round in any other company?? if s , y did they reject u????

- whats ur expectation from our company???? except salary??

   ( i told, training, work environment,)

- on what platfrom u want to work??????

   (i told development, testing and maintenence)

- any preferred place????

  ( i said NO sir)

- what r ur CO-CUURICULAR and EXTRA- CURICULAR  activities????

thats alllllllllllllllllllllllllllllllllllllll

 

(FOR PPL FROM  OTHER BARNCH  BE  PREPARED  WELL IN DATA STRUCTURE,  OPERATING SYSTEM, C , C++ , FOR TECHNICAL ROUND THEY GONNA ASK  QUESTIONS IRRESPECTIVE OF  UR BRANCH, BUT THEY PREFFER  E&C AND TELECOM…… HOW FUNNY U KNOW……!!!!!)

 

THANK U PPL……….

ALL THE VERY BEST…….
