You know Google is different from the moment you apply for a job.
There is no one person making the decision, it is a group of people who decide whether you get hired or not.
The managers do not have the power to hire or fire you because this is all done with packets.
Packets are reports by different people and they are more or less votes on making decisions.
No one person can make a decision. It is all done based on the idea that multiple people should choose you.
