I appreciate your feedback. I don't think I'm non-committal, more like afraid of being boxed into a too-small domain.

The last sentence is factually incorrect. During my time at FB I contributed code to the container solution, the Jenkins-equivalent, the network routing layer, the bare-metal-provisioner, the monitoring solution and even wrote a feature for the website. I identified a problem, parlayed with the owning team, and shipped that feature. This was the best part IMO about working at FB.
