Vantaggi
It's an OK place to be if you're a new graduate and this is your first work experience. Although not always true, you will likely stay far enough away from the toxicity. if you're lucky you may learn something useful for the first few years. Also, if you're desperate for a paycheck they do pay salaries, and sometimes they even pay the bonus that you're promised.
Svantaggi
If you're a seasoned professional, prepare to be told: 1) everything you've learned throughout your career is useless, 2) you have no idea how to do your job, and 3) you should be replaced by a 22 year old new graduate that just does what they're told. Then you'll be given explicit instructions to do things that you know will not work and expected to execute them immediately. Of course you will also be held accountable when they inevitably fail.
