Searching for career opportunities has landed him in a rut & we need advice on finding a new job out of school

My boyfriend lives in Orlando Florida & is currently studying to get a masters in industrial engineering. He currently has a bachelor’s in interdisciplinary studies in computer science & physical science. He has experience in computer science roles but is preferring to step into the world of industrial engineering. He’s been applying like crazy but hasn’t has any luck. Although he lives in Florida, he is really looking for opportunities in Austin Texas, but is applying everywhere. Any advice on how to boost his chances of getting of getting an interview? Anything helps, resume feedback, platforms to apply on, etc

btw I am an EE so I have no personal experience in the industrial engineering world
