Nvidia Interview Questions, Process, and Tips

The solution to determine whether a number is even or odd is to use the modulus operator with 2.

• Use the modulus operator (%) to find the remainder when the number is divided by 2.

• If the remainder is 0, the number is even. Otherwise, it is odd.

• Example: 7 % 2 = 1, so 7 is an odd number.

• Example: 10 % 2 = 0, so 10 is an even number.

Sockets, pipes, and inter-process communication are mechanisms used for communication between processes.

• Sockets are endpoints for sending and receiving data across a network. They enable communication between processes running on different machines.

• Pipes are a form of inter-process communication that allows communication between processes running on the same machine. They provide a unidirectional flow of data.

• Inter-pro...read more

Little endian and big endian are two ways of storing multi-byte data types in computer memory.

• Little endian: least significant byte is stored first

• Big endian: most significant byte is stored first

• Example: In little endian, the number 0x1234 is stored as 0x34 0x12

• Example: In big endian, the number 0x1234 is stored as 0x12 0x34

Function pointers are used to pass functions as arguments to other functions, allowing for dynamic behavior and flexibility in programming.

• Function pointers can be used for callback functions in event handling systems.

• They can be used to implement polymorphism in object-oriented programming.

• Function pointers are commonly used in sorting algorithms to specify custom comparison functions.

Polymorphism is the ability of a function to behave differently based on the object it is called with. Virtual functions allow dynamic binding.

• Polymorphism allows objects of different classes to be treated as objects of a common superclass.

• Virtual functions are functions in a base class that are overridden in derived classes.

• To implement a compiler, you would need to handle polymorphism and virtual functions for proper

A function template is a generic function that can work with any data type. When a template is executed, the compiler generates a specific function for each data type used.

• Function template allows writing a single function that can work with different data types.

• When a template is executed, the compiler generates a specific function for each data type used.

• Templates are a powerful feature in C++ that enable generic pro...read more

The maximum stack memory available cannot be determined using the given data structure.

• The maximum stack memory available depends on the hardware and operating system.

• It is not possible to determine the maximum stack memory based on the given data structure alone.

• To determine the maximum stack memory, one would need to consider the hardware limitations and the operating system's stack size limit.

• The data structure prov...read more

Process scheduling manages execution of processes, while thread scheduling manages execution of threads within a process.

• Process scheduling involves allocating CPU time to different processes, while thread scheduling involves allocating CPU time to different threads within a process.

• Process scheduling is typically handled by the operating system, while thread scheduling can be managed by the application itself.

• Examples...read more

Memory allocation in struct is not continuous because of alignment requirements and padding for efficient memory access.

• Struct variables may contain different data types with different memory alignment requirements

• Padding is added to ensure each variable is aligned properly for efficient memory access

• Example: struct with int, char, and double variables may have padding between them for alignment

Implement a custom malloc function to allocate memory of 16 bytes with starting address divisible by 16.

• Allocate memory using malloc function

• Adjust the starting address to be divisible by 16

• Return the adjusted memory address

The apti, coding test, and entire selection procedure were challenging but well-structured.

• The aptitude test covered a wide range of topics and required logical thinking.

• The coding test involved solving complex problems using programming languages.

• The selection procedure included multiple rounds of interviews and assessments.

• The overall process was rigorous but fair, allowing candidates to showcase their skills and abi
