ROBERT BOSCH PAPER ON 24th FEBRUARY 2008
hai, I am Devendra.s.kolkur(PDA COLLEGE OF ENGINEERING
GULBARGA, KARNATAKA). here I am submitting ROBERT BOSCH
question paper. I am from EIE background. There will be
separate papers for ELECTRONICS students and COMPUTER
students.
Friend prepare well all the topics which the is covered
since the tech paper is having all the topics
Which are related to Our engineering sudcts like
BASIC ELECTRONICS , NT,CONTROL SYSTEMS, ELETRICAL MACHINES,
DIGITAL ELECTRONICS, APTITUDE, & GEN PHYSICS & GEN ENGLISH,
C QUES PLAY KEY ROLE C & aptitude is very easy
Questions ; 60
Duration : 1 h
This paper is for EEE,ECE,EIE
Friendas just reffer the previous question papers that is
more than enough..... in this written test negative marks is
there correct answer carries 2 mrks. and wrong answer carry
1 mraks so be carefully answer.

ENGLISH section
Remaining r English ques Which contain Correction of
sentence , Synonyms & one puzzle which is very lengthy
Finally I clear the written test after the written 2
technical intervuew... I clear the first technical and out
in 2nd tech.
total appearance test :230
clear the test :21
first tech clear :8
than I dont know..... iam out in 2nd round
BOSCH ratio is 10:1 so prepare well in Technical mainly
concentrate to your academic project
Iam 2007 fresher from PDACE Gulbarga,Karnataka
Now Iam currently working in GE HEALTHCARE (GENERAL
ELECTRICAL )
And I feel tough
BEST OF LUCK
