It was very technical interview, interviewers asked to share the screen and notepad. I was supposed to tell the answer after analysing those. All questions were in C++, not only basic C++, but also from C++11 & C++ 14. They will ask with few basic questions then move to taugh questions, and at the end they will ask you to write the programs. Interview took more than 80 minutes.

Here is a list of Interview Questions asked by Vizio -

Question 1:

#include<iostream>
    
int main()
{
int x = 0;
if(x++)
    std::cout<< "Hello" << x;
else
    std::cout<<" Hello " << x;
    
return 0;
}

Question 2:

#include <iostream>
#include <memory>

using namespace std;

class MyObject1 
{
private:
    int data;
    
public:
    MyObject1(int aNumber) {data = aNumber;}
    int getData() {return data;}
};

class MyObject2
{
public:
    void doSomething(unique_ptr<MyObject1> ptr)
    {
        cout << "data = " << ptr->getData();
    }
};

//Will the code below compile? 
//If so, what will be the run result? 
//If not, how would you suggest to fix it?

int main()
{
    auto upObj1 = make_unique<MyObject1>(5);
    auto upObj2 = make_unique<MyObject2>();
    
    upObj2->doSomething(upObj1);
    return 0;
}
