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:

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.
