FEV Interview Questions and Answers
Q1. what is interrupt service routine, watchdog timer, lambda function, baud rate, CAN frame format, spi, Autosar related questions some
Interrupt service routine handles interrupts, watchdog timer resets system if it hangs, lambda function is an anonymous function, baud rate is data transfer rate, CAN frame format is used in Controller Area Network, SPI is Serial Peripheral Interface, Autosar is an automotive software architecture.
ISR is a function that handles interrupts from hardware devices
Watchdog timer resets the system if it hangs or stops responding
Lambda function is an anonymous function that can be p...read more
Q2. What is Constructor, is virtual constructor possible in C++, Virtual destructor with implementation.
Constructor is a special member function used for initializing objects. Virtual constructor is not possible in C++. Virtual destructor can be implemented.
Constructor is a special member function with the same name as the class, used for initializing objects.
Virtual constructor is not possible in C++ as constructors cannot be virtual.
Virtual destructor is possible in C++ and is used to ensure proper cleanup of resources when an object is destroyed.
Example: virtual ~ClassName()...read more
Q3. What is Friend function, Getter setter, Static variable and static function with implementation
Friend function is a function that is not a member of a class but has access to its private and protected members. Getter setter are methods used to access and modify private variables. Static variables are shared among all instances of a class. Static functions are functions that can be called without an instance of the class.
Friend function allows external functions to access private and protected members of a class.
Getter setter methods are used to get and set the values o...read more
Q4. Getter setter implementation, implementation of virtual function, difference between encapsulation and abstraction, focus on OOP
Understanding getter setter, virtual function, encapsulation, abstraction in OOP
Getter and setter methods are used to access and modify private class members respectively
Virtual functions in C++ allow dynamic binding and are overridden in derived classes
Encapsulation is bundling data and methods that operate on the data together
Abstraction is hiding the complex implementation details and showing only necessary features
OOP focuses on creating objects that interact with each ot...read more
Q5. Diamond problem program with approach
Diamond problem occurs in multiple inheritance when a class inherits from two classes that have a common base class.
Diamond problem can be resolved using virtual inheritance in C++.
Virtual inheritance ensures that only one instance of the common base class is inherited.
Example: class A is inherited by classes B and C, then class D inherits from both B and C. Using virtual inheritance for B and C in D resolves the diamond problem.
Q6. Have you designed gate driver circuits?
Yes, I have designed gate driver circuits for various applications.
Designed gate driver circuits for power electronics applications
Utilized MOSFETs and IGBTs in gate driver circuits
Implemented protection features such as overcurrent and overvoltage protection
Optimized gate driver circuits for high efficiency and reliability

Q7. Network setup at branch location and data center
The network setup at branch location and data center is crucial for efficient communication and data transfer.
The network setup should be designed to meet the specific needs of the organization
The network should be secure and reliable
The data center should have redundant systems to ensure high availability
The branch location should have appropriate hardware and software to connect to the data center
The network should be monitored and maintained regularly to ensure optimal per...read more
