It was my first ever interview, and it turned out to be with a guy from their core search engine team. I blew it big time. I had no idea what kind of questions would be asked. I wasn't even informed of the position I was interviewing for.

I had applied for software dev/machine learning. It turned out to be machine learning, which I wasn't prepared for at all.

Plus, I was very nervous and scared. The interviewer was not at all warm and supportive; he laughed at my silly mistakes and was quite blunt at times. He did try to help me out in several places where I blanked out, though.

It was a rough first-time experience!

About how random number generators and pseudo-random number generators work.

The last one was finding K-largest numbers in an unsorted collection.
