If there's anything we learned from our old pal Jack Dawson - there's just not enough room on that float for everyone. It's easy to be charmed by the illusion of a good brand, decent pay, and a handful of (fast diminishing) genuinely kind folks. However, once you settle in and remove your "Rose"-colored glasses (ok, last Titanic reference, but I hope you catch the drift this organization is quickly sinking) you'll discover this isn't a place you want to be. In fact, just peek under the surface and you'll realize it's extremely toxic and literally EVERYONE else wants to be as far away as possible.
As referenced in the "pro" above, while the leaders are arguing over the decisions they already made, you'll have plenty of time to exhaustively search for valid ways to make an impact. Once you realize that's a futile plan as no one really cares about employees' ideas and opinions, your extra time will be consumed meeting with other miserable colleagues who are also planning an escape and navigating the best way to handle the constant backstabbing and negativity.
So unless you're looking for a soul-sucking career guaranteed to make you become as incompetent as the management team, runnnnnn (or in this case swim - as fast as you possibly can)!!!
