Dell EMC Drive Interview Experience
The drive was conducted on their Dell EMC Office Bangalore. Around 50-60 people participated in this drive.
Round 1: Written Test
- Predict the output.
class A
{
public: A() { std::cout << “Constructor A\n”; }
~A() { std::cout << “Destructor A\n”; }
};
class B: public class A
{
public: B() { std::cout << “Constructor B\n”; }
~B() { std::cout << “Destructor B\n”;}
}
int main()
{
A *a = new A();
B *b = new B();
A *a = new B();
return 0;
} - Implement counting sort (array elements ranges from 0-99)
- Print numbers from 1 to 100, odd numbers with one thread and even numbers with another thread.
- int arr[] = {1, 4, 6, 7}
int n = 4
Allocate 2d memory with rows as n and each row has column equal to the elements present in array.
Like 1st row has 1 column
2nd row has 4 column - Can we play a game that require 4GB of RAM on a 1GB RAM. If so, how ?
