I am looking to possibly take on a new job in another building. My only experience with controls/building automation has been with siemens. I have gone to several customer classes for siemens and have been pretty involved with the programming here on site. the place i am considering is all johnson controls. talking to the HR rep for johnsons, they have hired people before with siemens only background and they have done well in the company. have any of you made a switch of this type and how was it? thanks. looking forward to reading the comments.
