Hi kimbob ,
I’ve gone through the process with Northern this year and been successful , just awaiting a training course , all I can advise is try to structure your answers using the STAR method
Situation
Task
Actions
Result
Give as much information as you can , don’t rush , and don’t be afraid to go back to a question , the scenarios are your time to shine , and also don’t forget to research what’s going on in the company , who’s who , etc ,
Get through this part then just the psychometrics to start on ,
I to am a conductor
