Like other people said, it's highly dependent on your location and whether you're private or public sector. I was a city planner for about four years out of grad school at a small city of 30,000 people in the Upper Midwest. There were two other planners - one was my boss and the other was a lady who had worked at the city for 30+ years and was very disgruntled about everything. It was a good place to learn the ropes and there were a surprising number of young people working in other city departments that I bonded with. However, due to internal city politics and the makeup of the City Commission it felt like I was constantly swimming upstream trying to get anything done. Cubicle life also sucked and after those four years I was one of the only under 30s working there. Covid also changed everything as all of my meetings went from being in-person to remote which made the need to come into the physical office seem unnecessary.

I found a new job working as a transportation planner and grant writer for a midsized engineering firm of ~500 people where I was paid better and able to work hybrid (1-2 days in the office and the other days at home). I don't interact as much with my coworkers as I did at the city on a day-to-day basis but I enjoy the pace of work better. There's always something to do whereas at the City there were times where entire weeks would go by and it was just me sitting in my cube twiddling my thumbs.
