Bosch embedded interview prep

Automotive supplier. Embedded teams here focus on integrating a safety-relevant AUTOSAR component on an ECU with CAN diagnostics.

Automotive supplierIndia hiring: HighSafety and standards Field and vehicle protocols C, memory and debugging Test and validation

Roles they hire for

AUTOSAR SWC and BSW developer
ECU integration and system test engineer
ADAS base software developer

What they emphasise

Classic AUTOSAR SWCs, RTE and BSW configuration with ARXML
MISRA C, ASPICE, ISO 26262 and ISO/SAE 21434
UDS diagnostics (ISO 14229) over CAN transport (ISO 15765)
Optimizing performance and memory on constrained ECUs

How the rounds usually run

A typical automotive supplier loop for embedded roles. Companies vary by team and seniority.

Written or online test

Aptitude and logical reasoning
C programming and core electronics
Sometimes basic networking and OS

Example: What is the output of a signed and unsigned comparison in C, and why?

Technical 1: Embedded C and MCU basics

Embedded C, pointers and memory
Microcontroller peripherals and interrupts
CAN fundamentals and your final-year or work project

Example: How does CAN arbitration work, and what happens on a bit error?

Technical 2: Automotive domain

AUTOSAR layers, RTE and BSW
UDS diagnostics and ISO-TP
ISO 26262, MISRA and ASPICE awareness

Example: Where does a diagnostic request travel through the AUTOSAR stack, from CAN to the application?

Managerial or process round

V-model and ASPICE work products
Estimation, customer communication and reviews

Example: How do you handle a customer requirement that conflicts with a safety requirement?

HR

Motivation, mobility and compensation

Example: Why automotive software?

Practice questions

Original questions written for Bosch's focus areas, not leaked ones.

Explain the AUTOSAR layers and where a new sensor driver would live if no standard BSW module fits it.
A UDS request arrives as a multi-frame ISO-TP message. Walk through reassembly and what can go wrong.
Name three MISRA rules you'd expect a reviewer to flag most often, and why each exists.
An ECU misses its 10 ms runnable deadline after a feature is added. How do you find where the time went?
How do you make a CAN signal safe end to end so the receiver detects corruption, loss and stale data?
