The interview process is great if you know what you are doing. After five interviews, I received a letter stating that Google had suspended all new employments.

About three months later, I contacted them again because they had opened the position for hire, and I was told to apply again.

I am happy that I met very nice people and skilled engineers, but it is a waste of time when it comes to the hiring process.
