Electronic Engineering Graduate applying for Automation Engineer Graduate Program

I’ve applied for an Automation Engineer Graduate Program as its an area that has interested me (as im not the biggest fan of electronics) without getting the chance to experience many modules in the area. My degree has occupied most/all of my time over the past 2/3 years but now that I’m finished up I would like to exercise some self learning in areas that would be of benefit to me for an automation engineering role

Could anyone give guide me a heads up on what the areas to start to cover? And is there any online resources you would recommend?

Try ISA training. They are the leaders
