Robert Bosch Test paper and interview
This is the ‘Robert Bosch’ written test on 14 th November. This test is for freshers (direct recruitment by company with call letters) Only 60 to 70 people (mechanical) were allowed to write the test who came with call letters. Only one mechanical paper of Bosch is available in our site. So I am  sending this paper. This pattern is for mechanical students.

Duration of test is 90 minutes and  there is negative marking also.

SECTION 1.

Questions Breakdown:
out of 50 questions, 40 were from our mechanical engineering related questions and 10 from aptitude.

SECTION 2.
Total 25 questions on English.
