BOSCH REXROTH


2008 Placement PAPER PATTERN for Bosch(another Exclusive u won`t get anywhere else)

Section 1:This section has only technical question. They are mainly from Pointers in C, C++, Data Structures & some questions on OS, DBMS.This section also has lots of question on bit conversions (HEX to Binary, decimal) & one question on finding 2's compliment & such others. There are few questions on finding TRUE/FALSE statement which was bit confusing. Question to calculate square root, cube root of a number were also included.
Overall, this section is easy if you are good with your basics. The questions are mainly around the basic concepts only.
Each question has four options (A, B, C, D) & we had to find the most appropriate answer. Each correct answer carries 2 marks & there is a negative marking of 1 for each wrong answer. So be careful while attempting these questions.

Section 2:This has only general English questions. No book will help you to answer these questions; instead you should have good knowledge of grammar & different English works.
There was a paragraph with some blanks in between. So we have to find the appropriate words to fill in, from the given options. Other questions include comprehension, synonyms, proverbs type question & others.
This section needs some intelligent guessing as you feel that all of the given options are correct & sometimes all are wrong.
Each correct answer carries 1 mark & there is a negative mark of 0.5.
