If "top-tier tech companies" are so much better than everything else, why do many employees leave them and never look back?
That's simply because they're not so much better than everything else. I used to work at Google. Google offers stable employment, competitive salary + benefits (not the best, but highly competitive), good work life balance, etc. The work I did was actually interesting too. It wasn't maintaining legacy code or working on stuff with no business logic. However, the thing is many other companies have the same features. It's pretty much only here and in competitive universities that you see people not "respect" companies that aren't thought of as top tier. I worked at multiple startups/small companies before Google as well and they were all great workplaces and had their own unique challenges. Working at companies like Google allow you to say you work at Google as well as work with many really smart people, but that's pretty much all that I can think of. I guess at Google you can also test upcoming products which was pretty cool, but pretty much everything else is standard. There's a lot of reasons why people would leave these companies and work at other ones: Working with friends/past coworkers Less stress/competitive environment if team was competitive (at big companies this is always team dependent) Better pay (yes, small companies may actually pay more) Higher position, more responsibilities or the opposite Working on preferred tech More on reddit.com
