When I graduated from industrial engineering, one of the most common questions I got was - “Where are the IE jobs?”
Yes, it is difficult to get a job or an interview or anything for that matter. However, I internally developed something what I call “EIE Technique” which is Everything is Industrial Engineering. To explain it more visually, I wrote something here -

Basically, at the end, I got a sense that no matter what, the demand for industrial engineers will always be present !
Hope that helps and motivates all you IE professionals:)
