Bosch Test Paper & Interview Pattern

•Duration of Test: 80 min

•Number of questions: 75

•Number of sections: 2

•No of questions in section 1: 50 (Technical)

•No of questions in section 2: 25 (General English)

NOTE:

1. This patter below is for computer science (CS) students only.

2. There was another set of paper for MECH branch students.

Section 1:

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

Section 2:

This had only general English questions. No book will help you to answer
these questions; instead you should have good knowledge of grammar and different
English works.

There was a paragraph with some blanks in between. So we had to find the
appropriate words to fill in, from the given options. Other question included
comprehension, synonyms, proverbs type question and others.

This section needs some intelligent guessing as you feel that all of the
given options are correct and sometime all are wrong. Each correct answer
carries 1 mark and there is a negative mark of 0.5. Hope the information given
by me here was useful to you.
