Question 1
Optimize this code (like what compiler would reconstruct an equivalent source code as):

int sum = 0;
for(int i=4*a;i>0;i--)
{
sum+=b*i*i;
}
return sum;
}

I applied through university. The process took 1 day. I interviewed at IBM (Waterloo, ON) in Sep 2014
Interview
There was a general meeting with everyone prior to the individual interview.
One on one, lasted for 45 minutes.
Asked generally about my resume, projects I've worked on, what I wanted to get from all this, general interview questions. Then this is followed by some technical questions.
At the end was told about what IBM does and given chance to ask questions.
Very casual overall.
