Embedded systems are specialized computing systems designed to perform specific tasks within a larger system.
Embedded systems are typically found in everyday devices such as smartphones, cars, and household appliances.
They are designed to be efficient, reliable, and often operate in real-time.
Embedded systems often have limited resources such as memory and processing power.
Examples of embedded systems include microcont...
Deadlocks are situations in which two or more processes are unable to proceed because each is waiting for the other to release a resource.
Deadlocks occur in multitasking environments where processes compete for limited resources.
Four conditions must hold for a deadlock to occur: mutual exclusion, hold and wait, no preemption, and circular wait.
Example: Process A holds Resource 1 and waits for Resource 2, while Process ...

I applied via Recruitment Consulltant and was interviewed before Sep 2023. There were 2 interview rounds.
Basic aptitude testing same like Greeks for greek
Structure is a user-defined data type that groups related variables under one name, while union allows multiple variables to be stored in the same memory location.
Structure allocates memory for all its members separately, while union shares the same memory location for all its members.
Structures are used when all members need to be accessed independently, while unions are used when only one member needs to be accessed ...
I was interviewed before Oct 2023.
Yes, I would sell the product to generate revenue and reach a wider audience.
Selling the product can help generate revenue for further development and growth.
Selling the product can help reach a wider audience and increase market presence.
Examples: Microsoft selling Windows operating system, Adobe selling Photoshop software.
Debouncing is a technique used in software development to prevent multiple rapid triggers of an event.
Debouncing helps in filtering out unnecessary or duplicate events that occur in quick succession.
It is commonly used in user interface interactions like button clicks to ensure a single action is triggered.
Debouncing involves setting a time threshold during which any subsequent triggers are ignored.
Example: Preventing ...

Smart pointers are objects that store a pointer to dynamically allocated memory and provide automatic memory management.
Smart pointers help prevent memory leaks by automatically releasing memory when the pointer is no longer needed.
Examples include unique_ptr, shared_ptr, and weak_ptr in C++.
unique_ptr is used for exclusive ownership, shared_ptr for shared ownership, and weak_ptr to break circular references.
A lambda function is a small anonymous function defined in a single line of code without a name.
Lambda functions are often used in programming languages that support functional programming.
They are commonly used for short, simple operations that do not require a named function.
Lambda functions can take any number of arguments but can only have one expression.
Example: lambda x: x*2 defines a lambda function that doubles
Threading is a way for a program to split itself into multiple simultaneous tasks.
Threading allows for parallel execution of tasks within a program.
Each thread has its own stack and runs independently of other threads.
Threads can communicate with each other and share resources.
Example: A web server handling multiple client requests concurrently using threads.
Lambda function is an anonymous function in programming that can have multiple parameters and can be used as an argument to other functions.
Lambda functions are also known as anonymous functions because they do not have a name.
They are often used for short, one-time tasks that do not require a separate function definition.
Lambda functions can take multiple parameters and return a single value.
Example: lambda x, y: x + ...
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 Recruitment Consulltant and was interviewed before Apr 2023. There were 3 interview rounds.
A Watchdog timer is a hardware or software mechanism that automatically resets or restarts a device if it stops responding or functioning properly.
Watchdog timer is used to prevent system crashes or freezes by monitoring the system and resetting it if necessary.
It is commonly used in embedded systems, where reliability is crucial.
The timer needs to be periodically reset by the software to prevent the system from resett...
A compiler is a software program that translates code written in a high-level programming language into machine code.
Converts high-level code to machine code
Checks for syntax errors
Optimizes code for better performance
Examples: GCC, Clang, Visual C++
Volatile memory is temporary memory that loses its data when power is turned off.
Volatile memory requires constant power to retain data
Examples include RAM (Random Access Memory) and cache memory
Data stored in volatile memory is lost when the device is turned off
