If one hates their job, it probably means that it isn't the right job for them. You just haven't found your niche yet. Some people like Cisco's slovenly culture of not really giving a damn - because it gives them the lee-way to not put in much effort themselves. Some like the lots of vacation and good benefits. Many are just still working on their preferred way out.
But it sounds like you'd like to build something, be something, make something fun with people who care. If that is the case - I highly recommend the startup culture. If you want Beer drinking on Fridays, Nerf wars after the big product release, Friends building something cool - you probably want a job with about 5 - 150 employees.
Corporate is for people who want to come in, do a job, and leave and not think about it or care about it. For people who have outside concerns they care about more and just want a paycheck.
And as far as your watercooler chats - it's not you. It's just that most folks at Cisco want as few meetings as possible to get the job done. The business sells buggy w4ips (basically, we sell horse-drawn carriage speed-up devices).
We are a hardware routing and switching company in the age of wifi routing and switching. We missed the boat on most of the big tech movements, and many folks around think we are in managed decline. We've had layoffs every year for about a decade. The people left at Cisco are riding the down-ward wave and relaxing until the company either croaks or finds a new direction to take.
It isn't normal to hate your job. This culture is especially toxic. The ELT are completely out of touch and haven't talked to the "pleebs" in years. The ESG garbage is absolutely ridiculous and counterproductive (we are already diverse and caring, having 5 meetings on it a week is just a waste of time). The tools and software we use are outdated and dysfunctional and make our work more difficult, rather than streamline it. Our data is mostly made-up garbage. And it just isn't a fun place to work.
If you want fun, productive, or carefree - Cisco just isn't the place.
You've gotten some experience under your belt - go use it to go somewhere fun, everyone deserves to enjoy what they do :-)
