If you are reading this on Glassdoor, you are not part of the inner circle, the boys club, the ones who stand to make a profit from an IPO. You should continue looking elsewhere.
You will be treated as a disposable employee with very little say in your work or your career.
In addition, some managers are rude, degrading, and offensive. Those managers are allowed to float across positions because they are part of the inner circle.
If you are part of the inner circle, enjoy the ride!
