In a big company the same building is full of people I do not know 👥

In a big company, even when we are in the same building, it is full of people I do not know.

It is a company with several thousand people or more, so I am constantly meeting people for the first time.

There are often times when I cannot tell at a glance whether that person is from the same company or from another company.

This was one of the things that surprised me about working in a big company.
