Loose management; the company's overall direction changes constantly, so you are often suddenly told to stop halfway through a task. Over time, you come to realize that you don't need to do anything—whatever you do might just be canceled tomorrow anyway. Perfect for people who like slacking off; you'll have a great time, like a fish in water.
Anything not mentioned under the advantages is a disadvantage. Simply put, after joining this company, your life from then on will truly be a mixture of joy and worry.
