I’ve found that people who work for large companies are often not a fit for smaller companies. They may be good developers, but most of the time they come in with prebuilt infrastructure, processes, separate departments to handle the infrastructure parts etc.

Most small companies I’ve worked for, I’ve had to go back and forth between every layer of the stack - currently including the infrastructure set up. You just don’t get your hands dirty with multiple parts of the stack at a large company.
