I applied via Campus Placement and was interviewed in Jul 2022. There were 3 interview rounds.
They will share the link of different languages for code test,
we need to select one language.
I had chosen c.
Interview questions for Embedded Software Engineer including Autosar, function definition, structure and union, microcontroller and microprocessor, and communication protocols.
Autosar is an automotive software architecture standard.
Function definition specifies the code to be executed by a function.
Function declaration specifies the function's name, return type, and parameters.
Structure is a collection of variables of ...
A program on structures using pointers to declare them.
Use the 'struct' keyword to define a structure
Use the 'typedef' keyword to create a new type name for the structure
Use the '->' operator to access structure members through a pointer
Example: typedef struct { int x; int y; } Point; Point *p;
Example: p->x = 5; p->y = 10;

I2C is a communication protocol used to connect multiple devices in a network. In Linux, the speed of I2C can be configured.
I2C speed can be set using the 'i2cset' command in Linux
The speed can also be configured in the device tree
The maximum speed supported by the hardware should be considered when setting the speed
Different devices may require different speeds for optimal performance
A pure virtual function is a function declared in a base class without implementation, which must be overridden by derived classes.
Pure virtual functions are declared with the syntax: virtual void functionName() = 0;
Classes containing pure virtual functions are called abstract classes and cannot be instantiated.
Pure virtual functions provide a way to achieve polymorphism in C++.
Example: virtual void draw() = 0; // decl...
Embedded C is a subset of the C programming language, specifically designed for programming embedded systems.
Embedded C is optimized for resource-constrained systems with limited memory and processing power.
It includes additional keywords and features for controlling hardware directly.
Embedded C often involves working with microcontrollers, sensors, and other hardware components.
Regular C can be used for general-purpos
Structure is a collection of variables of different data types while union is a collection of variables of same data type.
Structure allocates memory for all its variables while union allocates memory for only one variable at a time.
Structure is used when we want to store different types of data while union is used when we want to store only one type of data.
Structure is accessed using dot operator while union is access...

Dangling pointers can be avoided by setting them to NULL after freeing the memory they point to.
Always initialize pointers to NULL.
Set pointers to NULL after freeing the memory they point to.
Avoid accessing memory through a pointer after it has been freed.
Use smart pointers or garbage collection to automate memory management.
A program to print Fibonacci series using recursion.
Define a recursive function that takes an integer n as input
Base case: if n is 0 or 1, return n
Recursive case: return the sum of the previous two Fibonacci numbers
Call the recursive function with the desired number of terms and print the result
I applied via LinkedIn and was interviewed in Nov 2023. There was 1 interview round.
A virtual function is a function in a base class that is declared using the keyword 'virtual' and can be overridden by a function with the same signature in a derived class.
Virtual functions allow for dynamic polymorphism in object-oriented programming.
They are used to achieve runtime polymorphism by allowing a function to be called based on the type of object it is called on.
Virtual functions are declared in a base cl...
Polymorphism is the ability of a function or method to behave differently based on the object it is acting upon.
Polymorphism allows objects of different classes to be treated as objects of a common superclass.
It enables a single interface to be used for different data types or classes.
Examples include method overloading and method overriding in object-oriented programming.
