One YouTube employee said during the shooting people were trying to get out of the building "as fast as they could."
"We were all suddenly aware of a lot of noises, of sounds, people running outside of the room where she was. And people screaming," said the employee, who was in a building down the street.
Another YouTube employee says the fire alarm went off at the company's headquarters and workers didn't realize it was an active shooting.
