My views are in line with those already expressed. Whatever has been your experience in non-IT, you would have definitely learned something during this period. This can be technical, commercial, behavioral, or related to your job. Carefully make a note of these to answer a most likely question in any interview. You should state the fact that instead of idling, you have gained some experience and also acquired some learning. This will be appreciated. It depends on your presentation skills during the interview.
