This was the stupidest interview I have ever attended.

I was told to code two questions before a phone screen and passed that. I then proceeded to the phone screen where a person called me and asked a very simple tree traversal question.

I solved it using recursion first. He then asked me to solve it in a different way, which I did, and I provided him with three other solutions. All this took less than 20 minutes. I had written working code that you could compile and run.

And then I received a rejection the next morning.

I am relieved that I got a reject because God knows how people work at this company.

I would never recommend anyone to interview with them. There are much better places to work in Seattle, so please don't even consider this to be an option.

For those who are still going to take a shot, I think they filter out code sample answers by looking at the timestamp of your files. So make sure that the date/time of creation and date/time of last modification are not more than one hour apart. A simple solution would be to solve the questions, create a new file, paste the solved questions, wait for about an hour, modify the file, and then send it.
