Yes. It happens all the time and has certainly happened to me. I don’t have a simple answer. It isn’t just small to big companies. I also had an problem moving from enterprise to a smaller web related company. In that case, I went back to college part-time and retrained. Hard work but it turned out ok. I also did a series of government projects, which I really enjoyed, without thinking too much about it and then had a hard time moving away from that. The truth is that whatever you do, someone is going to pigeonhole you. It is just human nature. I try hard to build skills in what I want to do next and then try to work on projects that use those skills. One other thing I did was to present papers at user group conferences – often about what I wanted to do in my next project!
