Nokia Networks Interview Questions, Process, and Tips

Global variables can be accessed from any part of the program while static variables are limited to the scope they are declared in.

• Global variables are declared outside of any function while static variables are declared inside a function with the static keyword.

• Global variables can be modified by any part of the program while static variables retain their value even after the function they are declared in has finished...read more

An optimised prime number program is required for Senior Software Engineer position.

• Use Sieve of Eratosthenes algorithm for better performance.

• Start with 2 as the first prime number and eliminate all its multiples.

• Continue eliminating multiples of primes until the desired range is reached.

• Use bitwise operations for faster calculations.

• Consider using multi-threading for larger ranges.

Program to implement a linked list with Add, delete, count and modify API features.

• Create a Node class with data and next pointer

• Create a LinkedList class with methods to add, delete, count and modify nodes

• Use a head pointer to keep track of the first node

• For add and modify, traverse the list to find the node to add/modify

• For delete, traverse the list to find the node to delete and update the next pointers

• For count, tr

Program for binary search algorithm

• Sort the array in ascending order

• Set the lower and upper bounds of the search range

• Calculate the middle index of the search range

• Compare the middle element with the target value

• If the middle element is equal to the target value, return its index

• If the middle element is greater than the target value, search the left half of the range

• If the middle element is less than the target value, ...read more

A function pointer is a variable that stores the memory address of a function.

• Function pointers can be used to pass functions as arguments to other functions.

• Syntax: return_type (*pointer_name)(parameter_list);

• Example: int (*func_ptr)(int, int) = &add;

• Example: int result = (*func_ptr)(2, 3);
