Robert Bosch Interview (Online test + Technical round + HR)

The selection procedure for Robert Bosch job is done in the following steps:

1. On-line written test
2. Technical interview
3. HR round

On-line written test

• Few aptitude questions
• Technical questions on microcontroller, digital electronics, analog electronic - opams, CMOS,etc.
• C language questions

Technical Round Questions

1. Draw full wave rectifier circuit. Which is better bridge rectifier or centre tapped? 
2. How to verify the health of the 1kb RAM without using checksum.
3. Write a code for moving average when the input is analog data.
4. Draw a memory map for accessing external ROM and write a code to access the external ROM.
5. A puzzle: 2 buckets measuring 3 and 5 litres respectively. How do you measure 4 litres?
6. Design a mod3 counter asynchronous.
7. Transfer characteristics of a clipper was given and told to design the circuit.
8. Draw the output waveform for a RC (also RL) circuit with a step input taking the outputs across R and C separately.
9. Write a code to find the value of the 5th bit in a 8 bit register.(C code using static)
10. Draw the architecture of 8051.
11. Memory structure of RAM.
12. Write a program to show the usage of stack operation.
13. Define the types of storage classes in C and write a program for each.
14. More questions on transfer curves. We need to design the circuit for it.
15. Design a system by using any sensors, microcontroller if required (If you are using a microcontroller write a C program to interface the same )
Problem statement: A bulb should glow whenever the bike driver accelerates the accelerator handle with the following conditions.
• Bulb on when accelerating
• Bulb off when decelerating.
• Bulb off when accelerated and maintained a constant acceleration.
16. More emphasis on projects :
• If I have used a microcontroller I should justify why I have chosen that microcontroller and not any other.
• How do you interface IR sensor to a microcontroller.
• Block diagrams and in depth understanding of each blocks.

This is the best book to learn Digital Design using Verilog HDL, VHDL and System Verilog

I suggest going through these books for Digital Electronics preparation:

HR round: (To read more about HR questions in other tech companies read here)

1. Tell me about yourself and your family.
2. Why should Robert Bosch hire you? (Tell 3 strengths with suitable examples to substantiate the same)
3. Why do you want to work for Robert Bosch?
4. Do you have any plans for further studies?
5. What are your achievements in college so far?
6. Have you participated in the Robert Bosch Inscribe? Tell me about the paper you submitted.
7. Do you have any specific questions regarding the job?

This is a book that I highly recommend for anyone to improve on their soft skills. This will not just help in your interviews but also in your day-to-day work.
