The interviewer over the phone asked me to describe an algorithm to find intersection of two arrays of integers. Also asked me to write pseudo code in a shared google docs session. I got the algorithm right the first time, may be not the most efficient right away. But with more prompts from the interviewer I nailed all his questions and gave improved algorithm. I was then asked couple things about what are the hardest things to test. And some other OOP questions. Thats it. He said 'thats good' couple of times. And at the end I felt I would at least get called for on site. But was told within 2 days that they did have anything that fit my profile currently. Not sure what ticks Google !
